90 GL1500 Carb. Jetting Question

My 1090 GL1500 got to the point I was afraid to drive it,
It would not idle (could not turn idle adjuster, it was seized) on take offs I had to raise the rpm's real high and almost red line the thing to get it to take off from a stop, when I was slowing down and down shifting the engine would dye out.

I took the carbs off and found the accelerator pump was not working and when i got into the float bowls the idle jets were almost plugged up!

I un-seized the Idle adjuster, I got the accelerator pump working, but when I pulled the jets out I busted one, so I ordered a rebuild kit off e-bay.

Jets in side my carbs. are 158 mains and 60 idle the kit I bought has 155 and 158 mains along with 50 and 60 idle jets, I live in Chicago area and 99% of my ridding is at this altitude.

Why do they sell the 155 and 50's in same kit and (should I?) or (I should!) just put the 158 and 60's back into the carbs right??


Thanks for your help.

You should gauge those jets to see if they are really the size they are supposed to be.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

The 155 main and 50 idle jet were for the 88-89 carbs. The recall changed the idle jet to 55 to get rid if the stumble at takeoff. You want the 158 and 60 in your carb for the 1990.

Also make sure the carbs are balanced. This makes a big difference on how the bike will run also.

put the rich ones in, both idle and main. with the crap we get for gas with the 10% ethanol, you are already 5% lean.
