- I learned how to make a really powerful motorized bike engine a while ago and liked it so much I decided to make some more, be safe. Get a good frame, good brakes, and wear a helmet gosh darnit!

This is cool I have always wanted one of these types of motors since I started in this hobby a year n a half ago. Can’t wait to get one myself.
email me we can make it happen, would love to work with you.
Where can I get mine balanced
Nice line up bro
I love the saws, I have a 58x39.5 set up. Husky 395xp big bore by Ken hinson
Been rebuilding one of these. Going to post up few videos in few days I guess. Going for the whole Stihl saw theme/paint on the build just for fun. I actually found that the Stihl Saw Cat box exhaust works really damn well on these builds. Surprised more people have not tried it yet! I just use the MS380 10 to 12mm crank bearing pins works great motorized bicycle builds. ua-cam.com/video/xPKRLpkpM_g/v-deo.html
i already have the Mz65 expansion chamber all i would have to do is change the flange right ?
Too small. 125cc expansion chamber
Nice job. Good details. Not sure what shaving the crank does to a 56mm piston. Lightening the crank doesn’t balance it and a heavier piston would need more counter weight in mathematics.... definitely post the link to hear them running.
Lightening the crank does balance it as I take material off of the side attached to the conrod, it is not a conventional method so I understand your confusion but it works great with these motorized bike cranks. Balance factor is hung weight/ reciprocating weight. Shaving off the metal near the conrod effectively increases hung weight and balance factor as a whole.
@@getitrunningdunning5588 a heavier piston such as 52-56mm is already in harmony to a degree. Pinching the low end and removing a few hundredths of play in your crank with a press makes more sense to me. You also are reversing crank case compression by adding volume, if anything it might keep the piston from cracking or longer life of your build but I don’t know how a light crank is set to a heavier piston and balanced.just my humble opinion sir.. again good job.
@@rogerstafford-wakeinc.2088 I understand how it can be confusing and appreciate your kind words, here is a video that might be able to help.
ua-cam.com/video/0hoE_MuFpPI/v-deo.html
I may do a video later on it, I think my best way of explaining it is that balance factor isn't based on total crank weight it's based on how much on the reciprocating weight the weight of the crank accounts for. Motorized bike cranks are not bell shaped like some, they are basically discs. Taking off weight around the side where the conrod attaches is essentially the same as adding weight to the bottom because both increase hung weight. I hope I'm explaining this well enough, I think I'll do a video soon where I can actually give a visual example. it'd be a lot easier to demonstrate than to explain.
Are they sold yet?
What expansion? For it
For the ms660
I'm going to use a BT80 to do a Minarelli build, I would use one of these cylinders instead of a Minarelli, but the quality of the Stihl cylinder's just don't seem to be any better than the factory Chinese cylinders, I'm sure the Stihl cylinders run much better, but I'm shooting for longevity, not speed, great video, thanks for sharing.
I like the Stihl cylinders because they have port durations made for higher rpm power, wider port widths for better flow, better transfer angles that promote scavenging, and of course the displacement. For those reasons I see them as superior to stock cylinders but I have no doubt a Minarelli is a good choice as well.
Bt80 does not have a compatible crank in it!
@@BuildBreakFix this is true how ya keep the clutch cable from coming out it has slot were the cable goes what's that all about
@@BuildBreakFix I think you're right - they use a short rod and a low hole piston. Since they have a unique crank design due to the centrifugal clutch and the stator rotor, you can't swap a regular log rod CG crank. Might be able to split the crank and swap the rod for a long rod, but it would be a pain to do.
@@dmoore0079 I have built a ms660 and ms460 lol in how to videos step by step how i build it videos lol plus i have whole balance crank video shows every type of rod used in these builds😋👍 but bt100 wrong length rod in it! 38mm crank perfect ms380 & ms460 not so much ms660.
How do you relocate the cilinder studs ?
I think some people just open the stud holes in the cylinder and then use helicolis in the bottom end instead of filling the holes and retaping them. Idk I still haven't built one yet myself but have seen lots of different ways people are doing it. mostly mess with puch mopeds but I'm definitely going to build one of these
I ride my 66cc legally in IL to work all the time, the outer dimensions are the same basically so police are good with it as long as you keep it under 20, I'm thinking your gorgeous little 100 would be to big for the roads :(
I've got a question for you the bottom half of the engine is that literally a standard motorized bicycle engine kit and the cylinder and head is what you're replacing with the chainsaw parts or is the whole motor itself from the chainsaw
Bro..if you would look up at a 460 saw motor vs a 460 mini Frank you would tell the difference in half a second maybe less
How big this power engine?
I need one of these motors now
How much and where can I get one
What's your website ? IM INTERESTED
I'm curious to know if you think a Husquvarna 3120XP top end is a good candidate for a frankenstein engine? That's what I want to do. Your thoughts?
I'm not too familiar with that type of top end so I looked it up, from what I see it has a 42 mm stroke. Just make sure your crank and cylinder are for the same stroke. Motorized bikes typically have a 40 mm stroke but I've seen 38, and I think I've seen some people put larger cranks in them but I'm not sure. The port durations aren't going to be the same from factory because of the smaller stroke (if you put this cylinder on stock motorized bike crank). I think it would be able to run but probably not as well as you would like, I picked the stihl ms660 cylinder because it was the largest bore I could find with a 40mm stroke. I'm really not sure how well that husky one would work, but I'd definitely be interested to find out : )
@@getitrunningdunning5588 Thanks! Yeah your comment really underscores I'm a rank amatuer when it comes to these bikes. I thought I could just bolt it on and call it good.
@@mattparker9726 Yep, there's a bit of machining that usually needs to be done, it was definitely a learning experience first time I made one :). I recommend checking out gangster builder on youtube (he documented a ms660 build), it's a little cryptic but that along with various forums helped me figure it out.
How much is one of your engines with carb? Also have u ever used huskyvarna cylinders? A 394xp husky would be a beast that should be 94 cc
I have looked at some husky cylinders but they need to have a 40 mm stroke to work with this crank, I'm not sure if they make one like that. The one with carb is 415 but it's off the website for now because I have to weld the case in an area in order to reinforce it.
I'm pretty sure the 2100 cylinder is 40mm stroke I think you can buy aftermarket cylinders for them
I need that combination! Please🙏
When you have more??
Can I buy one
Yeah you'll be hearing from me soon
Keep it up
Are these for sale 🤔
Nice job. If I may ask what is the squish on these engines? I'm thinking about buying one or maybe two. Btw I bought one from another builder and it runs but the compression seems to be one weak side that's why I ask about yours. Thanks.
I line up the piston at bdc to the bottom of the exhaust port. I'd suggest to check that on the other engine you have. I had to take material off both the case and cylinder to get the correct squish, If you sand/file/grind down the bottom of the cylinder until the top of the piston is flush with the bottom of the exhaust port at bdc compression should be good (unless there is something else messing with it). I'd say try that and get back to me if it works, make sure not to take off too much to prevent piston slap. make sure it's flat too. You can do it with a file it just takes a long time. I don't measure squish, I just use the piston to exhaust at bdc method which works well. I see other people who make these make that exact mistake, where they don't take off enough material and have very little compression, I'm surprised some of them even work. Good luck, I hope you can get yours working.
@@getitrunningdunning5588 Thank you I will do that I did it an older 66cc because the two piece head/cylinder were leaking oil in between so I filed the mating surface and it worked out.
@@KenC56mm Stock cases are always a little misaligned, good on you for fixing that, always peeves me.
Nice, well let's see them perform. Talks cheap.....show me homie😎
Спасибо
Would you be able to ship to Europe?
I can if you cover shipping costs, it would be a bit more. Feel free to email me at getitrunninggdunning@gmail.com
and we can work something out. (yes two gs in running)
theres no way stock clutch is gonna handle that.. but great work!
On mine I have a stock clutch and it works alright, I did tighten the spring and scuff up the plate to help though.
How much
Subbed. Good stuff. Ill be experimenting with the ms660 to put on a yd100/phantom 85 v3 bottom end. I'm wondering how the jug mounting holes match up to the bottom end. No one out the shows measurements, but I guess I'll find out soon enough.
I haven't used those cases but am guessing they're similar to the ones I did use which were 66cc ones. The stud mounting holes are further apart for the ms660, so you'll need to fill, drill, tap. I got dangerously close to the edge so for my next engine I'll be trying to add some material with aluminum welding to have more space for the studs. I think the phantom 85 bottm end might actually have a wrist pin bearing that's the right size for this so it's a great choice but don't quote me on that, I'm not sure.
I was going to buy one of these Stihl engines but they're just not performing as well as the Vertical Hybrid Minarellis at 70cc.
I'm not sure if you're going off my ride video or not but I would like to say for the record I was running it way too rich, I leaned it out and it runs much better (actually revving up) I'll be uploading a new video soon so stay tuned.
You probably just don’t know how to make real power
@@justanothermotorizedbikech5138 ms460 big bore 54mm can be more powerful and don't let me get started with big bore 56mm ms660
@@Roberto_4273 dude go re read what I said.
@@justanothermotorizedbikech5138 i now. Am supporting you :v ms are better than minerelli
How much for one of these engines?
check out the website runningdunning.com
just added some new options :)
What kind of bearings?
stock
@@getitrunningdunning5588 oh
Ya know pgn has a good price on theirs and they way better than stock hell timken and skf have decent prices they are 6202-2rs and 6302-2rs-c3 c3is ceramic bearings low friction adds rpm but pgn are really good and cheap I haven’t built a mitor yet still learning it all ive did some mods tho lots of mods set squish skirting etc
@@motorizedbicyclenation53cu90 I've never had a problem with the stock steel bearings, but I appreciate the comment if anyone wants to upgrade. Yeah, that's how I started too just porting and messing around with different factors, It's fun stuff. If you ever feel the need to build a Frankenstein engine it's a fun project too.
Vai ficar um pouco mais forte
Will you ever restock??
Just updated the website, I'm doing individual orders now. www.runningdunning.com/s/shop
Are you seriously selling any of these
I need one
email me getitrunninggdunning@gmail.com
Man I want one. Are you going to be restocking these with carburetors? I dont get paid til around the 10th otherwise I'd prolly pull the trigger right meow lol
I still have the one with the carburetor, there was one guy who said he would buy it but hasn't yet, not sure if it'll still be here on the tenth but the website will let you know. So far only sold one, but once I've sold them all I'm thinking either doing another batch (bigger batch this time) or try something new like this setup but with a case reed and a custom exhaust flange. May end up doing some combination of those two things, also working on some other projects at the moment though. The one with the carburetor has a 21 mm carb, so basically it will have great throttle response but you might want a bigger carb if you're going for peak power, something like a 24 or 26mm. I did tune it for this engine and it'll will work well (had to lean it out from stock because of how much suction this thing creates). Everything's a tradeoff, anyway thanks for your interest and yes I will be restocking but need to do these things in batches to be time effective.
Lmao if only I had my income tax I would jump on it and throw it right on my already custom beach cruiser
@@deathx605 lol ty, you should make a video of that bike and put it on youtube :), it sounds interesting
I like
Do you still have motors for sale
I hate it when they don't respond, like why advertise it smh
@@danajett just buy from ken henson…. Everyone else is full of 💩
Can u! Ship that to sout tacoma washington....how much?
I think it's about 15 bucks for shipping throughout the US, If you go through my website it should tell you, link in description.
Can u! Sent your website i like to purchase tnk-u! Soo much!
@@garyfernandez8184 www.runningdunning.com/s/shop
only have one left now :)
Are you sure you did a good job on the build?Im trying to figure out if I want this motor or the minerali,they are both the same price,please email me because I don’t know.
The same price?? A minarelli build is $600-$700. I built a whole saw bicycle for $450.
@@justanothermotorizedbikech5138 But is it reliable as a minerli?
@@davidglobak What’s so reliable about a motor seizing from a single pull!?!?!?!?🤣🤣 My saw is untuned and will still pull without a single seize so🤷🏽♂️. With a saw you don’t even have to warm up the motor if you don’t want to. With the minarelli you must or you will seize
What's the Price's?
The one with the carburetor (tuned) is 415, one without the carburetor is 370.
I picked up the phantom it's a lot better then the rest on market but price range I would have except more. I'm gna order the ms60 jug set up .now with the piston set up on the crank they line up good ?
@@getitrunningdunning5588 what's ur thought of the jb weld heating up and mixing with the gas mix? If u did seal the sides up

If it is making 7 horse power wouldn't be legal in any state.
Who cares??!?! Police have enough to keep them busy. Don't run your bike on a highway and don't open it up with a ton of traffic around.
Stock 66 cc motors aren't legal in most,, 49cc is legal
@@artofdisguy3401 THERE all legal as long as you have a motorcycle license and have it registered as a motorcycle
junk saw motors lol
Let me know if you have more engines!! I’m interested
The engines are all spoken for at the moment, but I am interested in doing another batch, maybe with some new parts this time.
Style carburetor 😂😂😂
guess your little business selling these 660s didnt work out huh🤣
Why you have beef
How much
