Yz295 Kit, The YZ295 needs a specially machined cylinder head. Installation was easy and performance is outstanding. I bought an 03'YZ295 with an Eric Gore 295 top end awhile back. Pro Circuit still has the jigs for virtually everything ever sold, but doesn’t always have inventory. Lots I wonder if these kits would benefit from a smaller carb for some more velocity. Any help would be greatly appreciated. Im curious as to what others have theirs jetted at. This will be a father / daughter project so alittle info 2006 Yamaha Motor YZ250 M-Spec engine rebuild utilizing an M-Spec YZ295 kit. I believe people were saying it was a little cheaper and even better? Anyone know what I'm M-Spec YZ295 Big Bore Kits in Stock!
