gatoman28 Posted January 27, 2006 Report Posted January 27, 2006 Hello everybody: I ride in Glamis, CA - 75 during the day and 45 at night. It's about sea level, alittle below and alittle above in some areas. I have been told by one person to use 330 main jets with stock pilot jet. Then someone else told me to use 320 main jets with 27.5 pilot jet. Both said to put the needle in the 4th clip. Please help me: stock motor-no mods stock carbs-Mikuni 280 main jets right now stock pilot jet 25# 4th clip on the needle- the one that came with pipe kit Toomey T6 pipe kit K&N filters clamped one on each carb (2 ea - RU-0210) Any help would be great.

I have read the stock needles are better than the toomeys, but don't know that as fact. Quote

The thing to understand about jetting is that there is NO textbook answer. My bike may like a set of 330's riding right next to you at Glamis with a 27.5 pilot, while your's may only take the 320's and the stock pilot. Maybe the cases on my bike are better matched coming from the factory, maybe your intakes have a casting flaw in the runner, maybe, maybe, maybe... If you're looking to buy one set of jets and be done, you're going to be disappointed. I have every size between 270 and 340. The short, frank answer is to buy both, and try each to see which it likes better. I know I've said it before in a previous post, you should be pretty lean at 280's, probably a touch lean still at 320's and right in the ballpark at 330 or 340's. Just try one and adjust it if it needs more tweaking. Truly you should be rejetting for a temperature swing of 30 degrees, but you could go middle of the road, a bit fat at 75, and a bit lean at 45, but neither would be an extreme. Quote
BigRed350x Posted January 27, 2006 Report Posted January 27, 2006 LOL, um what jets should I run? I go from 80 Quote
