Good info. Very concise and easy to understand. I bought a new engine and when I went through it the clutch actuating pin is not centered in the shaft and the clutch plate is uneven. At least I know what’s going on in there. Thank you well done
Well done mister, Thank you for explaining everything clearly, Much easier than I first thought, I have a heavy duty spring that I got from a buddy and I ordered a Racing Super Clutch SAF clutch from Darcy Hemeon at DLH. You've helped tremendously with something I was hung up on. Thank You! 🏁👍✌
I like that you have a clean working station and that you take notes to help you remember what's up with specific parts & engine pieces. Very well explained and helpful for those who may need help. 👋🏁👍😎🙏✌️
My first motorized bike, engine from BikeBerry. Lots of issues wrong. The clutch was cracked. Replaced it. Now I find the clutch shaft is bent, causing the clutch to wobble on the shaft. Have a new shaft and bearings on order. Golly gee can't wait to see what happens next!
You can either one by all new gears or buy a whole new lower housing by the way I'm sorry for the loss of the clutch that sucks I have a motor showing up 2 stroke for my motorized felt liner Cruiser
I'm very interested in seeing your video about clutch bearing replacement. Heard a few conflicting answers as to the size of the upgraded roller balls to lessen bevel gear "slop" and rattling noise. Curious as to what Your opinion is.
My problem is I just got my new shark pro kit and I decided to use a drill cause I couldn’t start it at first from just riding it cause the wheel would just wouldn’t go so the screw just twist do I need a new bottom end it starts but my clutch arm go all the way back and wheel keep spinning
How do I get that little gear loose? It just all turns through to magneto case. My little gear is wobbling like crazy. how do I make it stop its disengaging and wont drive
You started strong. The video was perfect up until the point where you got lazy and didn't install the bearings, and that whole thing where you leave out how to install the sprocket and you just placed the cover with the arm bar up with your hand and told us that it should work fine, instead of just really doing it and then demonstrating it working for us to see. You should fix that because people need videos like this one. I still gave it a thumbs up.
I appreciate the feedback man. Maybe I’ll take the time to re do it and see if I can fit in more details and such. I admit it was one of my first videos, bit of a novice at video making at the time.
hey. oh you know, just living life lol. i have so many different things i do that motorized bikes has just been pushed off to the side for a while. i didnt go to the socal race a week ago, between work and not having enough money to drive down it just didnt work out. ill try to get a video out sometime soon, just been so busy with everything else. thanks for checking in man, i appreciate it.
Do you have to split the case to pull that hole shaft assembly apart ? I removed the clutch plate and with no pressure on 5he clutch I can only turn my back wheel a half of turn then it seems like it's locked up it's a brand new Zelda 80 engine it's probably got 1 mile on it . I noticed once I got everything together when I would pull the clutch handle in and walk the bike it seemed like it had a tight spot in it when I would roll the bike . If you could give me any ideas it would be greatly appreciated .
Awesome information. The piston side of the engine is fairly easy. The clutch side seems to give the most problems and requires more maintenance. It has more moving parts and adjustments. Thank you very much for this help.
Hey do have ant ideas on why my engine is putting when it first stsrt to go.i cut the muffler ran a straight pipe and 5ook air filter off .I adjusted the carb to no avail when it's at idle I turn it back up so it dnt shut down on me when I pull clutch in but at idle its high I dnt like hearing it like that but if its cuz I lost compression for piston and I need to keep it high fuck it its good
Whats going on out there in motorbike world.... 1st love the video... just seeing it...very informative.. but i have to ask did Any of you get the answer to why Motorbike wont crank & clutch wont disengage? Im having exact same problem with my bike. Thx for any help.
Ok i don’t know if this is related but my bicycle chain got out and stuck on the rim and the tensioner got it turned the tensioner bracket and now the rear wheel isn’t spinning its stuck anyone knows what could it be?
SO I JUST ASSEMBLED MY 2ND BIKE 100 CC INSTEAD OF 50 BECAUSER I BLEW THE FIRST MOTOR UP BUT THIS CLUTXH IS STUCK INGADGED HOW DO I FIX THAT I CAN PEDAL MY BIKE RIGHT NOW WITHOUT THE MOTOR TURNING
That ball bearing goes inside that little shaft then that shaft pin which is that metal bar slide behind it and that's how everything engages I hope I explained it
Hey there just what I needed help!!, I recently got my first 80cc was running great for about 2 weeks then started making-clinkin =clankin noises took off the clutch cover and saw that those 3 studs were grinding there way through the clutch cover from the inside out??... what do you think the problem could be?...
Sounds like those studs might be backing out some. You can tap them back Into place with a hammer. They pretty much just act as a small wedge. Give them a smack to put them back in place. Shouldn’t hurt anything by hitting them a bit. Just not to hard.
Where can I buy new clutch pads? Good ones. Not the ones from China. I just bought a new motor and only rode the bike twice and the pads already need replacing. Also, my bike is a daily user and I need to get more power to the road. Which wheel sprocket do you recommend for that?
Good video, very informative. Do these parts come from the factory already lubed? "Cause it sounds to me like the first thing a purchaser should do is disassemble this and lube it before installing the motor in the bike...
Thanks for the video but i have a question, the little push pin and the bearing wont fit back into my motor where they are supposed to be, its like it got longer or something, has this ever happened to you or do u know how i can fix it?
I followed ur instructions but when I was putting things back on, I put my bearings in and then tried putting my spring assembly back in. Realized I was screwed and had to take bearings back out on one side.
Where can I buy a very good pull starter for my bike? I bought one of the Chinese ones and it kept breaking the cord and finally just busted within a week. So I got my money back. I want an American one if it's available.
You can leave the engine completely together and remove the clutch shaft from the engine. It will come out, you just need to pull the clutch basket off and use a mallet to push it out.
Dear Sir-Do you recommend applying a small amount of grease to the crank drive gear and the clutch gear?Been doing this on my 49cc Grubbee GT-2B Skyhawk for about 11 years. I also put a small amount of grease on the bucking bar and ball. The clutch grips well but is a little sticky upon initial use. Was going to install the high temp orange clutch pads and hopefully reuse everything else, just removing the star retaining nut and outside plate/spring prior to replacing the pads. Appreciate any feedback-John in Texas
yeah you can use some grease on those gears, just not to much. i usually roll the gears through and make sure its only a light coating. to much it will sling around the inside of that cover.
HI! Great video! I just wanted to ask can I use any grease on this assembly? I have some bicycle lithium grease. Does it have to be temperature resistant for this application?
My new wildcat pk80 when it got shipped had many clutch problems, the actuator was stuck almost half way in. I took the flower nut all the way off and it went back to normal however as the flower nut would tighten so would the bar leaving me with very little adjustment when pulling in the clutch cable. it was ok for about an hour of riding before it started to slip really bad. I then yesterday tried to tighten the clutch spring which didn't do much to fix it, if anything I overtightened it to the point where I could barely even pull the lever in, the actuator bar was still most of the way in and the clutch was slipping not as much. any suggestions?
Did you buy the engine new and does it seem like the bucking bar could be shorter than normal/his and maybe the maker said fuck it just add bearings instead of changing the factory to make their bucking bars longer ? hahaha
I couldn't figure out why the rear wheel/chain was not releasing with the clutch pulled? Come to find out there was no metal ball/bearing in it. There was a tube spring in it so the bucking bar didn't function at all. Your video was the ONLY one that showed all the correct parts. Without it.... I couldn't fix it. Thank you!
The ball baring fell out when I was putting the chain on I put the bearing back in and the bucking bar sticks out too far and I can’t get the cover back on how do I fix this?
Tighten up your flower nut on the back side as tight as you can get it. Then with some longer bolts try to put the cover on and reach the case with the bolts. Tighten till you get the clutch lever to be able to press on the bucking bar. Then press the clutch lever arm and then tighten the flower not again. You should be able to put the cover on now or are close. Repeat till the cover seats against the case.
ok i got my moter and i am have big problams win i pull move the clutch bar nothing happins so hard stiff and i was told wing nut on clutch need be losses in lmk what ur think so win i move the big geer it all spins i can move the clutch at alll it so stiff i wood not be abull to sit still on my bike at any stop sorry for any miss-spelling add bad but hope u can understand it new moter any one seee tis has video help them with this problem pleezz sand to me
Bro y u stop making vids keep making em like this i learned a lot from this vid. I wanna know how the piston works etc and connect to the other parts of bike. Pls bro make some. I dont get the other channels.
@@wtmotobikes8838 ya bro pls make some more, i bought a bike like this from someone for a cheap price and rn it needs fixes. When i hold the clutch the back wheel turn smoothly then suddenly very hard then smooth again then very hard and it repeats this, i unlocked my sprocket cover and checked that the chains are ok and on point on the teeth so idk whats wrong, also the only difference i made when i dissasembled was i tried too hard to screw back the screw holding the sprocket to the assembly shaft or whatever is it called. Only vids like urs can help me so i hope ul make a vid that can fix my problem. Ty bro keep making vids like this ill give u the views even if i gotta do it alone it really helps me learn how this engine kit works and thats all i want so i wont be afraid to fix or fear problems and just enjoy my bike.
I have a new motor and the clutch takes more force to disengage than I'm used to. I'm building this for a female so I'd like it to be easier for her to pull the clutch lever. Is there a way to learn the force needed to pull in the clutch? Would loosening or tightening the shaft spring help? It's not my cable, I've already checked that
How long is the clutch arm? How long is the clutch handle? The amount of leverage on each is the factor that matters the most for the actuation of the clutch. If you have a short handle and a short lever, it would be quite difficult to pull the clutch.
@@wtmotobikes8838 they're both stock sizes. I was considering drilling another hole through the end of the clutch arm for the cable. There's room to make another one a couple of millimeters further out. Do you think that will make a difference?
Tightening the spring will make it easier, but then you will probably need to readjust the clutch-arm so your neutral button on the hand-lever will work again, good-luck.
GREAT INFO. I just installed a pk80 by runwell purchased from BMW. I started it and went to the end of the block and back, let it idle (had to turn the idle screw in all the way) I shut it of and 5 min. later I went to go to the store popped the clutch to start it and it slipped so bad it would not turn the engine over to start up. I TRIED to adjust the clutch with no luck. I found that the clutch pads were so tight in their holes in the cage that I believe that the only contact with the pads was the pressure plate. Wondering your thoughts on this. I don't know if you have encountered one of these (so called PK80 engines, NO rod markings) I have many questions about these engines, they are very different in design than my GT5 Pro Racing that I'm going to rebuild with I hope to be better quality components. THANKS AGAIN FOR THE INFORMATIVE VIDEO.
Did you ever figure this out?? I have a lower end kit more or less a hybrid China doll kit from BBR. When i 1st built it ran it around the block cool needed tuning than did 2 more shakedown rides than drove it to work a 3 mile trip i took it easy on the motor. Than on the way home i could not get it to start i had to peddle 90% of the way home i kept tring to start it with every hill after about 2 1/2miles of peddling it started made it home shut it off than started it again to see if it would it did but now again nothing wont start. Fule air spark are good.. im now thinking its the clutch going to check flower nut
@@trevorwotring3945 yes. It was a combo of things "i think" or i should say i fixed a combo of things and its now running well was running the motor is now being swapped onto a different bike lol but i had a very high oil to fuel mix and needed to rejet stock was to low so i was fouling the plug a little and i did need to adjust flower nut it wasn't tight enough. So i swapped out carbs for another stock nt carburetor but it was upjetted. I flushed gas putting in a new mix of 89 and 40:1 oil ratio. And i tuned clutch better. After that it ran fine! Could have been anyone of the issues above or the combo. I do know the motor dont like good gas it wants cheap gas lol really runs way smoother with 87/86
O and i did upgrade sparkplug to a ngk plug and i killed the kill switch! Just unplug the red wire and tape it down. Screw that thing the stock kill switch is trash even if you cut wires which is better for a stronger more stable connection they still go bad fast and will keep you from starting.. so i just keep my idle set low that way i can it turns itself off almost let it die down than hit choke its off
will u sell my used head affter markit my mom just passed a way i am not doing good can u sell me a used head affter markit for a cheep deal any deal lmk
I BIN TRYING TO BUY ONE FOR 2WEEKS BUT IF I CAN SPEEK TO SELLER HOW IF I EVER NEED HELP AM I TO GET A HOLD OF THAM U NO SO I HAVE NOT BUY ONE CUZ NO SELLER WILL EM,AIL BACK OR CALL OR FBOOK I EMAIL THAM THER STILL NOT EMAIL BACK
I can see that English isn't your first language, kind of difficult to follow your comment. You can email BikeBerry, call then or even chat online. They'll be glad to sell you an engine. Lots of 66cc engines out tjere with lots of companies selling them. Good luck JonnyC!
Rodney Brown thats tough man. It could tons of stuff. Is it completely stock? Stock port timing is horrible in these do that could be it. Stock jetting in the NT carbs is way rich, so that could also be it. Stock exhaust is like almost no flow, so that as well could be an issue.
just watching this video made me hit the like n Sub ya , to say my thanks want to see if your grease can match mine ? look up Pathfinder grease , keep-on keepin-on 808 gone
The bucking bar which pushes into a ball bearing is too far inset on mine. Have not disassembled yet. I suspect clutch shaft assembly trouble of some sort. If so, where can I order clutch shaft assembly parts from. I do have engine serial number.
I changed my bucking bar and the steering wheel, but the clutch still don’t get pressure, I think the bucking bar needs to be bigger, or I need to press something to get the space inside smaller idk what to do
You ever make a UA-cam video? It’s called being nervous lol. I’m not good at recording myself and keeping my composure. But thanks man. Appreciate the Criticism. At least I got the answer half right.
This video was very helpful. Simple.....straight to the point, and no endless babbling about stuff I don’t care to hear.... thanks!

There’s actually a pretty long list of things people should do to their engine before installing it in the bike, lubrication being one of them.

Yes, They do come "lubed" from the factory. Always good to check everything, like dude says.
Thanks for the video but i have a question, the little push pin and the bearing wont fit back into my motor where they are supposed to be, its like it got longer or something, has this ever happened to you or do u know how i can fix it?
Your going to have to loosen the flower nut on the other side to be able to get your clutch cover back on. Then you’ll have to re tighten it back up.

I started it and went to the end of the block and back, let it idle (had to turn the idle screw in all the way) I shut it of and 5 min. later I went to go to the store popped the clutch to start it and it slipped so bad it would not turn the engine over to start up. I TRIED to adjust the clutch with no luck. I found that the clutch pads were so tight in their holes in the cage that I believe that the only contact with the pads was the pressure plate. Wondering your thoughts on this. I don't know if you have encountered one of these (so called PK80 engines, NO rod markings) I have many questions about these engines, they are very different in design than my GT5 Pro Racing that I'm going to rebuild with I hope to be better quality components. THANKS AGAIN FOR THE INFORMATIVE VIDEO.
Did you ever figure this out?? I have a lower end kit more or less a hybrid China doll kit from BBR. When i 1st built it ran it around the block cool needed tuning than did 2 more shakedown rides than drove it to work a 3 mile trip i took it easy on the motor. Than on the way home i could not get it to start i had to peddle 90% of the way home i kept tring to start it with every hill after about 2 1/2miles of peddling it started made it home shut it off than started it again to see if it would it did but now again nothing wont start. Fule air spark are good.. im now thinking its the clutch going to check flower nut
miguel Rosario have you got it figured out?
@@trevorwotring3945 yes. It was a combo of things "i think" or i should say i fixed a combo of things and its now running well was running the motor is now being swapped onto a different bike lol but i had a very high oil to fuel mix and needed to rejet stock was to low so i was fouling the plug a little and i did need to adjust flower nut it wasn't tight enough. So i swapped out carbs for another stock nt carburetor but it was upjetted. I flushed gas putting in a new mix of 89 and 40:1 oil ratio. And i tuned clutch better. After that it ran fine! Could have been anyone of the issues above or the combo. I do know the motor dont like good gas it wants cheap gas lol really runs way smoother with 87/86
O and i did upgrade sparkplug to a ngk plug and i killed the kill switch! Just unplug the red wire and tape it down. Screw that thing the stock kill switch is trash even if you cut wires which is better for a stronger more stable connection they still go bad fast and will keep you from starting.. so i just keep my idle set low that way i can it turns itself off almost let it die down than hit choke its off

I can see that English isn't your first language, kind of difficult to follow your comment. You can email BikeBerry, call then or even chat online. They'll be glad to sell you an engine. Lots of 66cc engines out tjere with lots of companies selling them. Good luck JonnyC!
The buck bar isn't carbide it's probably 4140 HT.

Where can I get parts for my 80cc engine?
Donald Bowler idk all the places you can get parts but one place I know is bikeberry.com
eBay maybe?, lol
I got 2 motor and clutch assembly for parts the big heads not the 49
My motor is runnig slow what can it be
Rodney Brown thats tough man. It could tons of stuff. Is it completely stock? Stock port timing is horrible in these do that could be it. Stock jetting in the NT carbs is way rich, so that could also be it. Stock exhaust is like almost no flow, so that as well could be an issue.
just watching this video made me hit the like n Sub ya , to say my thanks want to see if your grease can match mine ? look up Pathfinder grease , keep-on keepin-on 808 gone
Nobody shows how to remove the clutch system.
The bucking bar which pushes into a ball bearing is too far inset on mine. Have not disassembled yet. I suspect clutch shaft assembly trouble of some sort. If so, where can I order clutch shaft assembly parts from. I do have engine serial number.
I've been getting all of my parts off of Amazon.
You nee d the ball bearing to go in before the bar
i take the metal bit off to feed the chain, when i put the metal piece back on its wobbly and loose
I changed my bucking bar and the steering wheel, but the clutch still don’t get pressure, I think the bucking bar needs to be bigger, or I need to press something to get the space inside smaller idk what to do
Dude you forgot to put the bearings
Iv considered making a newer video. I was pretty novice at making videos when I made this one lol
Volume
CAN U EMAIL ME BACK SO I CAN BUY ONE RIGHT NOW FROM U SIR
these engines were first made in russia
"A bearing or a marble", :-O
You ever make a UA-cam video? It’s called being nervous lol. I’m not good at recording myself and keeping my composure. But thanks man. Appreciate the Criticism. At least I got the answer half right.
