@Calum when I had a DTR years ago with pinned ypvs it had a higher top speed when I lowered the gearing as the motor was actually able to pull better via a ratio that in theory would have given a lower maximum
@Sven-Hackbarth there was already a thread on this it’s a good looking bike and more parts is never a bad thing in my experience AliExpress is pretty good quality I like the carbs especially
