Suzuki 2 Strokes

Just resurrecting this thread as I wondered if anyone ever fitted one of these with any success?

Thought I'd bump this for interest. We never stop learning, do we?

Not a power band issue but mate worked in a small dealer in 70,s fella came in & bought CB200 new .following week and every week it came back as he said it wasnt running right.road tested but all ok.eventually they fitted a pair of coloured cable straps around the carbs and told fella they had found the problem.pointed to the carbs and said the 'foofoo valves ' hadnt been fitted at pdi,he never came back.any problem we have is always the foofoo valves
