Haven't been on this forum in a few years. I'm sure this question has been discussed here many times. My bike has been sitting 3 years or so and has the Takegawa 124 +r engine. Had this engine size because of class restrictions and it ran very well. I'm ready to upgrade to a larger cylinder and TB stroker crank. What cylinder/piston will work with my +r head? I don't want to mess with the Take 178 s-cut (don't like the short skirt) and I plan on boring the cases for a larger cylinder. Any suggestions would be appreciated.
