just jetted bs32 cv carbs with a stage 3 dynajet kit and replaced all the o-rings. interestingly all of the float heights were about 2mm low so I brought all them back up to 22.4mm. started right up no problem but immediately went to about 5000 rpms. the idle screw is backed all the way off and the throttle cable isn't adjusted to keep open. what's happening?

Did you bench sync carbs- all throttle plates will appear evenly just about closed?
If not on idle stop screw, what's holding it?1981 gs650L

I re-bench synced the carbs and now it's better and idles normal when cold. the idle goes up to about 3000 when warmed up. Maybe running a little lean? the idle thumb screw is set as low as possibleComment

recheck your float heights are at the correct setting. 2mm is a lot to adjust them, are you sure you have the right measurements for your carbs?
if you have increased the height of the float, when measuring it, you are effectively lowering it in the bowl when the carbs are fitted. too low will cause a lean situation1978 GS1085.

When warm, can you adjust the idle back down using the idle adjustment screw?

Darn, with so many daily riders it's hard to decide which one to jump on next.
