I am new to Bultaco's and the forum, I have had lots of late 60's and early 70's Japanese bikes in the past and I acquired a #49 Sherpa T 250 that someone had previously taken the motor apart and loosely assembled again. It was missing the primary chain tensioner, the clutch springs, pins, etc, and a few other nuts. I am reassembling it now and am running in to issue of the counter weight not going down far enough and how to put the clutch pins in on the springs on the clutch basket. Everything else seemed to go together good. We put a new rod and bearing on the crank, new crank bearings and seals, and a transmission bearing. How does the tensioner mount? I can't seem to find any documentation on the internet for this model.
Thanks in advance.....Devin
