Hmmmm good to know. The mount for the engine is extended three inches back, so the tank and petcock on mine should not interfere any. I also have the head stud mod, but with threaded rod so there shouldn't be any issue with threads ending.
Thank you for the input. I think I may see what I can do with that one, and I may put much Puch one for sale. Its the "super street" which is more overkill than I wanted. If you or know of anyone that may want it, I will remove it and clean it up/inspect it.
