Thanks for your help, two more questions:
1. I’m not sure if I should buy a tlr 200 engine, or build a Tl150?
2. Is the tlr 250 engine completely different in size to a tlr 200?
Thanks
So I’ve seen that there had been a special hi-boy 305, with a big bore tl250 engine, I cant find much information on the conversion etc so wanted to know if there was anyone with any knowledge around the complexities?
