IDLE

[mpi]

I have a similar problem with my bike except it is in reverse.  The bike starts fine and will idle smoothly at 1k-1500 for the first little bit while I let it warm up (~5 minutes).  After about 10 minutes of riding, however, when I come to a stop the idle slowly decreases until starts to cough and I have to stay on the throttle to keep it from dying.  I don't notice any problems while I'm riding like loss of power or hiccups or anything, it is just at stops.  This problem also gets worse the onger I ride.

Could it be that my idle is just too low or is there perhaps a larger problem?  I tried to increse it last time I rode, but it didn't help, however I messed with it before I took off and not when it was acting up.  Should I expect the idle to decrease as the bike warms all the way up so that a reasonable idle when I first start the bike and come off the choke should be marginally higher than 1500?  I am going to try your easy clean method for the carbs and see if that helps me any.

Okay, bare with me on the description.

but i got it running nice.

I know that the carb cleaner has done wonders and it's getting better.  I am now going to drop the float bowls and spray some cleaner in the jets( my neighbor told me that i definitly have a jet issue.

I found something interesting.  As you take off the gas tank there are two black caps.  Under those are the spring valves.  one of the shafts was majorly bent.  I straightened it out and wow.   100% different.  runs so much better, but  you can still tell that a jet is clogged.

Batteries.  best batt for best price. place? cost? name?

Don't know if anyone knows about this one.

So it was running great this weekend.  Today I took it out for a ride and it wasn't running great couldn't get  it over 2000 rpms.  but i noticed when i applied the brake it ran better.  I noticed when i put on the brake the lights went on stronger too along with the dash lights.  I ended up driving with the hibeams on to get it to run well.

Thanks,

Check the ground and auxilary ground (hooked up to the negative terminal of the battery).  Somehow it was using the lights as a path to ground - if it is not the grounds, start checking each and every connection in the ignition system - make sure they are clean & properly connected.  If that does not solve it start looking at all the connectors inside the headlight.

SO glad I found this thread. First post, just got a mint 92 that prev. owner let sit for a long time, so it surges like a freakin bronco. Mostly in 1 and 2, on busy streets, with lots of pointing and laughing, I'm treated to an extremely embarrasing session of chug chug chug SURGE!  Can't wait to get home tonight to tame the beast. Local dealer wants nearly $250 for a tune up, so hope this works...

I would suspect your valve clearances are too tight and you're loosing compression when they warm up. The warmer they get, the worse it gets.

So how would I fix that problem?  Is it hard to adjust the valves?[/quote]
