Jetting!

[onefastbanshee]

I am a little about sea level and I also have temps ranging from 70-90. I just need to try some new ones and see what works or me. What pipes were you using?

What needles are in the carbs?

That is kind of wierd. Most people that run Keihin carbs both the pj34mm and the 35mm PWk's use a needle with the E in the middle. I am running keihin pjs with mods in my sig. I use the CEK.

I am pretty sure that your main is to big. I am in the process of jetting mine for the POD K&N's instead of the K&N proflow with no air box lid. I am at 160 with the CEK needle in the center clip position. I will probably even step down to a 158. Right now my pilot is a 62. It is way rich but for now i am working on the mains.

 

Try doing a plug chop to see what you get. Post the pics on here. Here is mine with the setup in my signature.

 

Just warm it up on the old plugs. Put new ones in and then do blast down a back road at wot for a min or so. Kill the engine and pull the clutch in so you dont mess up the readings. Cut the threads off. You will now be able to see how your engine was running at WOT.

thanks alot for your helpful insight. I will most likely tackle the jetting this weekend. I will definetly do a plug chop to get more of an exact answer. I am gonna start with 160 mains and a 55 pilot and see what results I get out of that. I am pretty close but I think I am running on the rich side.
