71 Bultaco Frame / Yamaha Motor

Featured Replies

What do you think of this? Came upon a 1971 Sherpa T basket case. Motor is shot (chunk out of case, wont turn over, etc) but the frame& wheels are good. I have several 74 TY 250 motors and was wondering if it would be worth the effort to put a yamaha motor into that chassis (providing that it even fits) ? Or try to make a Magesty copy? Any thought or suggestions?

Cheers. Mike

If it was me, not worth the effort, I'd find another Sherpa motor - much better performance than the TY which is also a bigger and heavier lump.

The TY exhaust port is central and will exit straight into the Sherpa down tube, so you also have to find a way of routing the exhaust around that.

Mike, If you fix the Bultaco you will have a piece of trials history. If you put the Yamaha motor in it you will own a ******* that nobody wants. Can you post photos of the Bultaco?

Mike - sound words of advice from Woody & The Observer - Don't do it!

Haven't taken any pics yet. (If I can remeber I'll try) but it is in rough shape. I only paid $100 us for it, for the price it was in great condition! (if I don't use it I will take it up to Mid Ohio in July to try to sell it)
