chimpy Posted September 24, 2008 Share Posted September 24, 2008 Hello people, i plan to re- jet my 2003 xt600e to suite a non-standard exhaust however im a bit confused with the twin carb set up. I have found a diagram of the carbs and have read from the exhaust manufacturers website that +10 points on the main jet would be a good starting point. Does this mean on the main jet on each of the two carbs? Sorry i've never done this before. Ps its a crd exhaust Thanks Link to comment Share on other sites More sharing options...
Moderator YamaHead Posted September 24, 2008 Moderator Share Posted September 24, 2008 If your XT is anything like mine.....it's actually a 2-stage carb (works like a 2-barrel on a car)....thus, the secondary barrel only opens after 1/2 to 3/4 throttle. So, there still is only 1 main jet in the primary side (where the fuel bowl is located). HTH @ least a little. Link to comment Share on other sites More sharing options...
chimpy Posted September 25, 2008 Author Share Posted September 25, 2008 Thanks for the reply. so i guess i only need get the one +10 jet for the primary side and lift the needle one notch higher. Cheers Link to comment Share on other sites More sharing options...
