Re: X2 cvt rear shaft spline stripped
Might try eBay, X2 pocket bike CVT transmission. There was a seller there that had CVTs but the ad says $1099.00, which I believe is a miss print, think they want $99. If you find them, contact the seller and ask them.
There are sprockets 11 to 17 teeth in #25 and T8F 8mm chain. You need to figure your final drive ratio, to know how many teeth to get. The closer the numbers of teeth offset the more top speed, the farther apart more low end, its up to you. Think you have T8F 8mm chain. Divide the front gear teeth into the rear number of teeth. A 11/33 tooth would be 3 to 1 plus the 5 to 1 of the CVT trans, gives you 8 to 1 final, that would be a high speed ratio. Also remember your engine turns backwards as mounted and the CVT reverses direction so your rear wheel turns forward. Also some early bikes had #410 chain.
I found CVTs on eBay, same sellers I talked about, $1,099.99 free shipping. I sent them an e-mail and offered them $99.99 for one, and told them no ones going to pay that much for an $80 transmission, so we will wait and see what they say.
