ok thanx guys , how much is a 400cc kit ? lol

 

if u get the 400cc kit u should deff get a full exhaust system not just a slip-on

 

The Alba 400 cc kit costs $1300.00 and the cases need to be split for the stroker crank to go in. If the bike has no major motor work, I think a 14 tooth sprocket would not be needed, even with 20s on the rear. I put the 14 on because after doing the motor the bike was a wheelie monster. The 14 calmed that a bit.

 

Also check out the FST 446cc kit it sells for only $700. Thats my next project.

 

Anyone know the four stroke tech website?

 

I don't think the web site is working anymore.
