420cc on a mini bike problem.

[Dmbjr02]

Hello everyone, I put a 420 predetor on a older mini bike frame and the problem is the clutch does not line up with the rear sprocket at all, it's like 8" off, the part the clutch goes on sticks out to far, what could I do do make them line up, would all torque converter or a jack shaft fix it? I am trying to do this for as cheap as possible, any help would be greatly appreciated.

Jackshaft and two pillow block bearings, you can change the gear ratio by changing jackshaft sprocket sizes or keep them the same.

Also, if you are wanting to do this cheap, just get a predator 212cc and it will fit?

Move the motor far right till it lines up and add a training wheel ?

Put a jackshaft between the engine and the wheel. It will allow you to adjust sprocket ratios and move the sprockets side to side for alignment.

You can use pillow bearings or use a clutch jackshaft assembly that has a plate with two bearings already mounted on it.

Update

I have resorted to just making a new mounting plate so that I can Mont the engine over to the right alot to match up, it looks kinda funky and might throw my ballance off a bit but I don't want to order a jack shaft and have to wait for it lol. I appreciate all the replys very much so thank you everyone.

No... You'll need to build a jackshaft, they don't make a js setup for bike like this... Most people just keep stock style engine....
Since this is an eccentric build...everything isn't going to be the typical.

Off balance 420 on a minibike... Sounds like a party. Make sure someone's videoing that first ride.

Should've done the jackshaft... it's only like $50. Have fun with a hospital bill

Still hoping for that video once he gets out of the hospital...

Some people just don't listen to good advice and it is a waste of time to even give them any advice! Use a jackshaft just like was suggested by the guys that know what they are talking about.
