jack-shaft 80cc kit 8 speed bike

[@deborahchesser7375]

I always wondered why a standard gear system couldn’t be used with a motor, I guess it can. Awesome

[@0-MACMAC-0]

shift a millisecond too fast and you'll find out why people dont use them alot

[@deborahchesser7375]

@@0-MACMAC-0 probably wind the chain up in a ball or break the hub itself. You’d definitely have to be gentle with it.

[@danieljonhson6367]

I always have to ask why people don't do it that way more it works a lot better if you can use the gears.

[@JamesPiccone]

It actually doesn't, they suck ballz. Not enough torque to efficiently use gears and you still have all that driving through a bicycle chain.

[@audieallen9734]

because it's a really difficult build, with a lot of things not quite fitting properly and guess work, trial and error. more things to go wrong...

[@deborahchesser7375]

@@audieallen9734 I always wondered the same thing, why couldn’t a standard gear change system work with a motor. I guess it can if you take it easy shifting like backing off the throttling during gear changes. Your right though, lots of test fitting and modifications but once I get a welder I’m going to start messing around with building some stuff. Like putting a 670 Vtwin industrial motor in a YZ,KX,CR,RM 250 chassis. Or a trail buggy, again with gears. ✌️🇺🇸

[@theLyzhendricks]

​@deborahchesser7375 this whole bike was built with kits a motorized bicycle kit and a shift kit/jackshaft kit

[@johnsheetz6639]

I bought one off marketplace that has that kit. I have seen some people that pulled it off but most people are against it because of the thin chain and the derailleur being weak.

[@vicentemacedo4896]

Good night. It would be great if we had these two engine mounts that hold the shaft that transfers the force to the other side. Like, they contoured on some A4 sheets, each support on a sheet, for pdf so we can make our own supports. Think about the partner idea. It would help us a lot in the shaft adaptation process. Thanks for the attention.

I know I'm 3 years late to this party but that thicker chain looks like it needed a tensioner. I'm making something similar to this setup but using an electric hub motor. Flopping chains are inviting disaster.

[@31ijah.V]

You gotta change out that stock exhaust for a better system like a chamber and muffler set to increase power! You already got the cnc high compression head so that is by far way better than a stock

How bad does the derailleur bottom out when starting?

[@Gamer-xk5rs]

Was the point of this is to get the most speed, if so cant you just use a smaller sprocket instead of the one it comes with that goes on the other side and wouldn't have to add extra weight? Or does it make a difference with both gear shifts that I don't know about.

[@dekoldrick]

Something like this would optimize engine's torque range for each gear so you can control if you want more power for acceleration and going up hills easier or more power for more top speed on flat ground. With only one gear, you'll have to settle for in between which won't be the best at both.
