the standard bore size is cheap as shit ( assume you have a steel sleeve in there.) can do wisco and yamaha, must have forgotten you :O) sorry i get easily distracted. the CD rings for the Wisco are universal to them so you they are thye same for the suzi kits etc, you just look up and buy the ring if its not in the kit liek a CD 2275 etc the rings are like $10 on ebay, like DOC and Leith said nothing wrong with wiseco, depends on the user and who does the clearances.
I have Rt1 standard bores unles you absolutely must have a yz curve. Ic an sell you a window or posibly a Piston port in 96/98 and you can scupt your own intake curve.
Depends how anal you are i guess.....................
