zookrick Posted October 11, 2015 Posted October 11, 2015 What manifolds do I need to put 36mm carbs on a '90 gsxr 750 that has the big 38mm boots?Can I just use different clamps and tighten them real good? 750 teapot manifolds? or some other ones? Quote
Captain Chaos Posted October 12, 2015 Posted October 12, 2015 (edited) Depends on air filter configuration, fuel tap placement, etc.If it's a stock 750 engine in a 750 frame I would think '88-'89 GSX-R750 rubbers would be fine.

Rene EFE Posted October 12, 2015 Posted October 12, 2015 You need the ones that (originally) came with the carbs. You could try with the current 38- rubbers, but in my experience, you'll make your life infinitely harder doing it this way. Quote
Captain Chaos Posted October 12, 2015 Posted October 12, 2015 all rubbers from 36-carbed bikes would fit, GSX-R750 J/K, 1100 K/L, B12 Mk1, and probably a few others.But the 750 J/K rubbers will get the carbs positioned at the right angle/height, B12 ones won't, about 1100 ones I'm not sure. 1 Quote
zookrick Posted October 12, 2015 Author Posted October 12, 2015 Does the '90 750 head have raised intakes like the short stroke heads? Quote
Captain Chaos Posted October 13, 2015 Posted October 13, 2015 Does the '90 750 head have raised intakes like the short stroke heads?compared to my B12 engine, the 750L's intake ports are around 10-15mm higher. Quote
