now that i have replaced the stock exhaust on my tw200 with a DG slip on,its very obvious that i need to do some carb rejetting. ive found several websites which have info and most of them have different info. a website called jetsrus.com has the main jet listed as a #126. and the slow/pilot jet is listed as a #31. is that correct? do the numbers tell you how big the hole is? if my tw200 is running lean with stock jets than what size jets should i get? what about the needle, does that need to be changed or adjusted in anyway? any help would be greatly appreciated!
