Another geezer here who enjoys messing with bikes that were new when I was young! I am new not only to Bridgestones, but to 2-strokes completely, being an old Triumph guy currently engaged mostly with small Honda 4Ts. I do not own a complete Bridgestone motorcycle, nor am I likely to: my focus is road racing, and although I admit that I have stripped at least one very nice, complete Honda CB160 to "racerize" it, I do feel that's a shame. I am currently gathering parts to build a BS50 Sport racer, with so far a 60 Surfrider frame and a couple of mostly-complete

60 engines (one from a Chibi). Besides tuning advice, my questions are likely to center on parts compatibility (like putting a BS50 transmission into the Chibi engine). But there are no doubt many members of this forum who know much better than I do what I
should be asking! cheers, Jack
