Look at my jetting please-Popping on decel and on gear change
Posted June 10, 2010 - 03:57 PM
Fuel Screw-2 full Turns
Needle 4th from top JD Red
RD Float bowl with acc pump cover and adj Pilot Screw
Header-Stock (but will be putting on power bomb later tonight which will lean it out a bit right?)
Airbox-Snorkel removed, high flow filter
Ride-I took it up and down the street. I could only go about half throttle because of the area. The bike is insanely fast even at half throttle. The bike was revving smooth and not hiccuping as I increased throttle, but every time I shift gears it would crack and pop, and when I RELEASED the throttle it would crack and pop. So this is where I am at currently. 170 may seem large but its working 10x better than the 165 did. Now how do I fine tune to get this popping and cracking to go away. Oh, TPS disconnected too. So what do I need to do for this decel and gear shift popping/cracking?
One more thing...I have a YZ cam to install but I dont know if that will totally jack up my current jetting or not. It will not be installed for a few weeks though so that I can get used to the power the bike currently offers.

Yep, go up on the pilot to 48. To get the right pilot jet and fuel screw setting, warm your bike up first. Then raise the idle a bit. You just want a high idle. Adjust the fuel screw all the way in, then move it out till you find the max rpm point. Youll know when you find it.
Anyone have advice? Do I need to up the pilot jet to 48 since im at 2 1/2 turns on the fuel screw and still have this popping? Or does the main need to go up further than 170?
Needle position looks alright, if it pulled alright at 1/2 throttle, leave it where it is.
With your main jet, you have to test it at WOT. If it bogs, it is lean. If it studders, it is rich.

Anyway, I put on the powerbomb header tonight and will do some airbox mods...so I might end up having to go up on the main. We shall see. OH and one more thing...After im done setting the fuel screw do i lower the idle back down?
