Idle problems after rejet
Posted December 20, 2008 - 04:53 PM
We put in the red needle with clip in the 4th position, 170 jet, AP mod.
Also removed the AIS, new K&N air filter and adjustable fuel screw (2 turns out). The exhaust is already uncorked, the grey wire is cut, the throttle stop shortened.
Once we got it started back up, it sounded a little rough but ran good while you stayed on the gas. Whenever you let off the gas, it dies out. Then it is difficult to get back started. We can't seem to figure out why it is not idling at all. Any ideas?

When we were installing a JD jet kit and was taking the top of the carb off, one of the plastic wheels fell off of the slide down in the carb and we had to take the slide out.
We also were doing the AP mod and somehow the spring lever by the throttle shaft got stuck back behind the wheel that holds the throttle cables.
We finally got the lever back into place and the throttle moves perfectly. The slide is also back in place.
The new needle and main jet are installed, but now the bike will not idle. When it hits it will run, but pull the clutch in and it dies.
What is the problem if the slide comes out?

secondly with more air going into the system via K&N you have to give it more fuel, which is the reason for poor idling. the pilot circuit is your idle circuit...bump up the pilot jet to a 48.
thirdly what is your altitude and temperature? i see your exhaust is uncorked but i think a 170 might be too much....if it was a slipon i might suggest a 168. try either a 165 or 168.

The altitude here is 6-700 MSL.
