Decided to try the famous Keihin Air Striker on the CR250. Got one at a decent price from a 2002 KTM 250. I had planned to rebuild it with a kit for a 2000 CR250 – since that is supposed to be about the best starting point with this swap. I’ve somehow managed to never have to mess with carburetors very much in spite of having had many bikes over many years – I guess stock jetting usually works. Anyway, that’s my excuse for not knowing much about slides. So will the # 6.5 slide that came with the KTM carb work fine, OK, or not at all? Or can I compensate somewhere else in the carb? I don’t see a #7 slide out there for much less than $70 – which of course is why I’m asking. Advice on the rebuild kit plan & slide selection would be appreciated.
