    I recently read here about putting the later 125 shift drum detent in the early 125.I've looked and searched but can't find the thread again.There was something about removing something in the cases for it to work. appreciate any help finding that info

    If a six speed is replacing a five speed then there are two places that need to be trimmed but since you're only switching out the shift detent on an existing six speed then I would say no modifications are required.

    Looking forward to the pics. Will you be riding or showing your bike. The only event I'm familiar with at Unadilla is Pro Motocross on TV.

    The weather was not good for that Saturday so I passed. Too much effort to go slop through the mud. As for the bike,I feel it has great power. Running a 32mm carb right now,like to try a 34. Shifting is perfect with the later setup. Would really like to swap back and forth with an elsinore. I feel it's that fast. There was a lot of development put into this motor.

    The cylinder is a non-reed 74,the head's advantage is cooling. I have a 74 head if needed.
