Mopar_440 Posted May 15, 2006 Report Posted May 15, 2006 I was wondering if anyone could help me figure what MM my carburetor is, I know there stock, and its a 89 banshee. Thanks. Quote
platinumjason Posted May 15, 2006 Report Posted May 15, 2006 If they are stock banshee carbs, should be 26mm. Quote
trex banshee Posted May 15, 2006 Report Posted May 15, 2006 Your right on the money there platinum. Quote
Rustbag Posted May 22, 2006 Report Posted May 22, 2006 Yamaha's website says 26mm so thats what I would say. But when I actually measure my stock carbs they are 28mm on the inner diameter. Anybody know why this is?? 1 Quote
racer Posted May 22, 2006 Report Posted May 22, 2006 they were probably mearsuring from a different spot on the carb. that or your stockers have been bored to 28mm. Quote

Did you check the inner or outter diameter? I dont know how Yamaha does the measuring, Id guess inner diameter. But if its not uncommon for people to bore out Banshee carbs. Quote
Rustbag Posted May 22, 2006 Report Posted May 22, 2006 It is possible mine are bored since the guy a bought my shee from raced it. The first time I rebuilt the topend I couldn't believe how much it was ported. Make since he might have done the carbs too. Quote
Animalman294 Posted May 23, 2006 Report Posted May 23, 2006 The measurement should be with calipers, and it will be the narrowest part of the carb that the air has to pass through. Stock is 26 mm, but if it is 28 you may want to go talk to the guy you bought the bike from........... Quote
