Just in case yall think otherwise... all of the clips are with the cylinder unported. None of them ported. Porting it just didn't succeed.
So you didn’t port the cylinder at all it’s stock or no
Undosputed heavyweight of the hobbby here
Late night rides gotta be the best
Only. With a freely good headlight
Hay Trent! It was so awesome seeing this video Pop Up! Your Bike is Screaming! And sounds Super nice! I really enjoyed seeing You make each pass. Each one sister and faster. Keep up the awesome work my friend and when I make a purchase from SP I will use Your link. I cant wait to see what You will build next. Your content it super Kool! Congrats on 2.72 K Subs! Stay safe out there.👍
Thank you man. Appreciate it
The algorithm served me this and I’m thankful for a new channel to subscribe to. Keep on going, this is really something!!!
And while I’m at it; Stay safe and use proper equipment, dress for the slide and not the ride❤️
Ty
Very, very well done, brother, man!! What a ripper you have hahaha great stuff, keep up the work! The bike looks dam good 👍 👌. Can't wait to see what you come up with next.
Seee im definitely building one for the summer to get back and forth to work
I would get pulled over so fast trying those high speed runs in my area!
@@jeffcard3623 haha
PS. Your Bike is the only Music Needed!!!💯👍
Curious on the distance you can travel on a tank riding like that hahahaha. Passing in the bike lane 😂 Love it!
probably 50mpg just full throttle if I were to guess
be safe ma bro those some scary speeds
Love the vids keep posting
That's a Very fast bike you done a great job building it and a great video 👍💯
thanks man
nice i like the handlebars
Damn a 36 tooth and 100km crazy I only got 57km max and I have the same size sprocket 😮
Hi, so you're the best gas bike mechanic I know. So I had a question for you about my gas bike. I had let my friend borrow my bike and he ran out of fuel, in a pinch he poured straight gas into the tank and put in a random bit large amount of oil. Now my bike won't run but it'll start up a little. Do you know how I can fix it so it'll run? I've changed the spark plug, took off and cleaned cylinder, and it just still won't run. What do I do?
I’m convinced ur going 70 ish bang on I use the same app getting 37 flashing on 43-45mph calibrated 40 sighns
@@2strokezoomies nah its 60mph+ in this video
Great content brother!
@@Farquad4532 thanks
Awesome. Video Trent, what app are you using on your phone for the speedometer?
GPS Speedometer + Odometer
@@trentbikes awesome thanks buddy Happy riding
ever tried using jackshaft kits?
no
Then on the same site theirs a yd100 with a oko carb and mz 65 clone pipe for 220 what do you think is better? Will weight matter im on the big side 240
Trent, show a video on your porting job...
@@Spooky-z8r no, it's useless. Cylinder is messed up anyway or something.
Hello trent!I have a 80cc china doll engine i got on ebay and have it running and it goes about 35mph top speed,what upgrades should i do?Was gonna upgrade it and ride it until it blows up and get a minerelli head and piston like you have
Check out my upgrades and mods video
13k rpm is impressive. Did you upgrade the 4 engine bearings?
Sorry me again i had another question go max industries has a pk80 kit with a cnc head and mz65 clone pipe what do you think? For 200 bucks as a starter kit for now?
Sure, doesn't seem like a bad deal.
Why not put a chainsaw carb (tillotson ) on it with the mxs jug
@@damnthiccassboye7138 because I haven't built it yet.
Thinking of getting the Menace 85 soon. Your thoughts on it? Will definitely be using your code
@@777goncharovv I think they're good, better than p85 and a85
Can you put small cvt gearbox on it?
Would have to do enough modifications and mounting to do that. You would have to swap the bevel gears to sprockets and a chain, and also the sprocket being much smaller for the clutch shaft, for it to work. Because otherwise the clutch shaft spins at very low rpm so it wouldn't work.
@@trentbikes make sense
@@shamgarcia2000 RDM does have the chain drive kit.
last time was messing with stock avenger85 and its new dellorto 21mm carb and achieved 38mph on flat i think its possible to upgrade the carb more but idk maybe u can say what else i could do more for top speed and perfomance boost?
Gotta try a different sprocket and maybe a pipe. I ran an avenger with smolik head,mz65,32t sprocket and a bofeng I bored the roof out of and did 50mph+ constantly l.
Do you have a 32t sprocket on your avenger?
yes
Great video, so how much would that exact motor cost me
$900-1000 including genuine carb and rmh pipe

Cool! Nice to see you build another engine. Athena sport is 12hp right? There is a new design with 19hp but it costs 3 times more. Im gonna get that one after i finish my first build with the stock cylinder. Do you use the stock needle bearing for the piston or you change it? I cant find any other with the same dimension. PS Maby your reeds are worn out/bent?
Nah I said in the video the reeds isn't the problem. I checked and tried everything. I forgot to mention this in the video but the cylinder is scored from the dji action camera test video. I cleaned it up and the piston and reused it, ran fine in the bike build video, then all of a sudden it doesn't want to go past 40mph anymore. I swapped ignition system and carb, fixed case issues (stripped stud threads) and what not until it finally ran right, then same issue, put on a new piston kit, ran fine again, saved it for porting, same issue comes back and no luck. I'm willing to believe the cylinder is too worn now.
Anyway idk about 12hp, thats a possibility yeah. I'd say around 10hp more or less. The mxs is a Zuma racing vertical 19hp jug, but in the real world on bicycle engines, probably 15hp+ depending on setup
@@trentbikes Oh yeah you did mention reeds. Well my guess on what you said is that it gets overheated but doesnt seize. That probably makes the piston ring/rings worn out of tolerance. Have you tried the trick where you drill small holes down to the piston ring from the top of the piston? Maby try new rings with a higher gas/oil mix?
@meskalin64 I did put on a new piston kit (47.6 airsal piston, flat dome, but same size, new ring too) and it did seem to help. Got up to 58mph smoothly. Then saved it for porting and it doesn't want to run right anymore. Probably my porting anyway. Eventually I noticed compression was low, yes I tried mix ratio, and while I was editing the video, i realized I forgot the squish gap after replacing the case (different height). It was 1.3mm. Set it to 0.7 and compression was higher again. It still didn't help tho. So yeah idk. It's strange because it was running fine like how it was (scored plating and blown piston but cleaned up) for miles, now it does this. And I honestly doubt it's my porting. Besides mxs, I need to get a new cylinder kit, like a cheap iron minarelli and try again (had issues with my old iron one) or athena hyper
@@trentbikes Ok good luck. Im sick atm (flu) so i havent started with my build yet. Im mostly looking at videos about it and ordering parts. Got my exhaust with silencer today. Found a cheap one 100$ made for minarelli. Then the plan is to make my own one for the other cylinder.
Gonna go for low end power on the stock cylinder and speed with the other.
U need a tail light bro
Nahh
I don't even go this fast in the car
@@mrbing70 you don't drive on the 70mph highways?
And I got a bt 100 and I got to go 108 kph
No you did not.
Do you have a speach impediment? Not making fun, just interested. Different is good anyway
I'm deaf, but also yes I think
60mph is insane! Nice! But going those speeds you should wear actual gear bro, falling off at 20mph is enough to hurt you bad. 60mph wearing a t shirt, you’re going to turn into Swiss cheese. Change that habit now before you learn it the hard way. Seriously! We care for you!
@@sasquatch_886 and with that mxs jug, I might be able to hit 90.
If someone invented a small, reliable, bolt 🔩 on 2 or 3 speed gearbox for these 2 strokes. They could make a lot of money. It'd help with climbing hills, top speeds & make engine last longer running at lower rpms....I seen a bolt on gearbox for motor scooters 🛴 but it looks too bulky for these 2 strokes.
I think a good solution would be a 2 gear box composed of 2 small bevel gears of different sizes and two clutches of different sizes as well. The high gear one could be activated by centrifugal force coming from the wheel so it would engage only in high speeds
@@GuilhermeTrojan I was just looking at some old 1960s Mineralli 2 stroke moped engines that were 2 & 3 speed....With cable shift & twist grip shift, the engine & gearbox combined look about the same size & design as a cheap china kit....All someone needs to do is clone it's bottom end and give similar bike frame mounting brackets. Or clone the Simson moped engines.
reliability is of more value than speed
speed turns this bike into a suicide machine
it's OK for dirt bike racing on an actual track
not so with competition on the road dominated by two ton tanks and such
that's a death machine
@@dependswhoyouask you don't know any of the bicycle parts I used.
