OKCterror Posted September 4, 2008 Report Share Posted September 4, 2008 not sure, but measure the side that goes in the intake and convert it to mm. just a guest Quote Link to comment Share on other sites More sharing options...
jar banshee 01 Posted September 4, 2008 Report Share Posted September 4, 2008 get a ruler or something that measures mm and i think you measure across the small opening that gos to the cylinder Quote Link to comment Share on other sites More sharing options...

98_banshee_newbie Posted September 4, 2008 Author Report Share Posted September 4, 2008 I tried doing that but first I measured my stockers and they are coming out at 28mm not 26 so I do not know? Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted September 4, 2008 Report Share Posted September 4, 2008 Got any numbers on the carb? josh Quote Link to comment Share on other sites More sharing options...
differentstrokes Posted September 4, 2008 Report Share Posted September 4, 2008 You can compare the pictures in the carb diagram section to your carb or if it has them, match up the numbers on the side right above the float bowl... http://sudco.com/ Quote Link to comment Share on other sites More sharing options...
98_banshee_newbie Posted September 5, 2008 Author Report Share Posted September 5, 2008 this makes sense now I wonder why I thought that stock was 26mm for. One of those days I quess. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted September 5, 2008 Report Share Posted September 5, 2008 measure the ID with a mic, ruler or calipers on the engine side of the carb... stock carbs are 28 not 26 youre wrong homie. stock banshee carbs are NOT 28mm. they are 26mm..

fastrthnu Posted September 5, 2008 Report Share Posted September 5, 2008 after double checking yamahas website.. i guess i am wrong.. yea measure the small end that faces the cylinders from the inside with calipers or a small bore guage, then do an inch to mm conversion if needed. a stock banshee mikuni carb is 26mm.

98_banshee_newbie Posted September 5, 2008 Author Report Share Posted September 5, 2008 never the less the keihin sight has 4 different ways to measure your carb to distinguish the size it is. And they actually go by measuring the OD and matching that up with there chart. the only catch is the only real difference according to there chart is a couple mm of difference in the whole height of the carb. Which I have found really hard to do with a metric tape measure(accurately). I called the guy at sudco and he told me to measure the ID of the hole and I measured 34mm not 33 and not 35. Fuck the metric shit to much room for error. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted September 5, 2008 Report Share Posted September 5, 2008 you need calipers to accurately measure that shit.. these are keihin carbs right? there should be a number stamped on the side.. Quote Link to comment Share on other sites More sharing options...
