2001 GS500 problems after valve adjustment

[jdmskier]

I just ran it with the filter off. It has the same problem 

[ryott52]

Well if it was running well without the airbox on it would seem that that's your issue. Any chance there's something that got blown free of the filter and is now blocking airflow?

[jdmskier]

I really doubt it, but i will go look

[ryott52]

Maybe the bike's running really rich then, and when you take the filter off it lets enough air in to get a better mixture?

[jdmskier]

One thing that I just noticed. When the bike hasn't been started for a little bit (15 min) It will start right up without giving it throttle. Once I give it throttle, the revs drop slightly and if i let go, the engine dies. From there on, I must hold the throttle to start it again.

[jdmskier]

If I have the petcock on PRIME, should the a lot of gas be coming out of the carb if I give it full throttle?

[jdmskier]

Another thing I just noticed.

I had the choke on for a long time. When I take the choke off, it starts right away and revs (slowly) to about 3000rpm if I give it gas, but it won't go above that.

I just checked the timing chain. According to the manual, it is off by 3 sprockets...that is probably my problem. I am going to fix it this weekend.

doh!!!  Don't beat yourself up over it.  My first bike, Honda Sabre 700, I did the same thing.  At the time, didn't know what I did wrong and sold it cheap.  Wish I would've had a great community like gstwins then!

If you have gas coming from the carbs then you either have a sticking float needle or the float level is way to high.

Damn. Like ryott52 my guess would've been a messed up mixture screw =)

jdm, do you recall way back in the beginning of this thread when I wrote;

"Did you actually change a shim or did you just check the clearances? Unless you left something out or did something pretty drastic ( pulled the cam shaft and jumped the sprocket ) it shouldn't be the valves".

sounds like it could be from reinstalling the cam shaft caps, the notches on the ends of the cam shafts should point directly at each other or away from each other.  I usually only loosen the bolts to be able to like the cam shaft a little bit.  You will still probably have to readjust the white plastic knob to get it just right after your done. good luck
