So the 52mm is a true 88cc kit? 51mm=85cc kit? 50mm=82mm?

I currently have a 52mm piston, stock 90 head, and stock crank. If i bought the 54 mm stroker crank that would give me a 115cc motor. What else would i have to buy other than the crank? will it bolt right in?

Hey Z,

I'm not sure about the 54mm crank..? but yes the 50mm should bolt right in. there are other things you have to be carefull of:



1). the skirt on the piston, the extra rod length may make the piston's skirt hit the crank when the piston is at bottom of the stroke..!



2). some stroke kits require that the cases are PRE BORED for clearences.





Thanks.......OLDSCHOOL
