98_banshee_newbie Posted September 4, 2008 Report Posted September 4, 2008 Hey I just bought a used carb how do i know what size it is? It is a keihin pwk Quote
OKCterror Posted September 4, 2008 Report Posted September 4, 2008 not sure, but measure the side that goes in the intake and convert it to mm. just a guest Quote
jar banshee 01 Posted September 4, 2008 Report 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
98_banshee_newbie Posted September 4, 2008 Author Report Posted September 4, 2008 that sounds logical enough Quote
OKCterror Posted September 4, 2008 Report Posted September 4, 2008 i was so right, thats how you do it Quote
98_banshee_newbie Posted September 4, 2008 Author Report 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
OKCterror Posted September 4, 2008 Report Posted September 4, 2008 are you measuring the inside diameter??? Quote
jbooker82 Posted September 4, 2008 Report Posted September 4, 2008 Got any numbers on the carb? josh Quote
differentstrokes Posted September 4, 2008 Report 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
98_banshee_newbie Posted September 5, 2008 Author Report 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
locogato11283 Posted September 5, 2008 Report 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.. Quote
fastrthnu Posted September 5, 2008 Report 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.

locogato11283 Posted September 5, 2008 Report Posted September 5, 2008 after double checking yamahas website.. i guess i am wrong.. its ok. everyone makes mistakes.. cept me. :biggrin: Quote
98_banshee_newbie Posted September 5, 2008 Author Report 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
locogato11283 Posted September 5, 2008 Report 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
