Hey guys, I have a questions which I have researched, but I'm not sure if they apply to my problem:
I've had this weird stalling issue that I've tried to address in the forums before, by changing the battery, air filter, spark plugs, and oil and oil filter; basic stuff like that. I'm due for more maintenance so I thought I would try and resolve it.
Basically only after warming up the bike, it stalls when coming up to an intersection. No sputtering, weird jerks, or anything out of the ordinary; just a smooth stall as I pull in the clutch, brake, and throttle off. You can see it reach the idle and then just die (as if it's not getting gas or air; I'm not sure, just speculation).
This only happens once, maybe twice after "warming up the bike". Once it's warmed up or I've been riding more than 5-7 minutes the bike has never stalled for me (or at least I don't think it has). BUT, one thing I did notice is that when I do come to a stop after it's completely warmed up; when I pull in the clutch the rpms drop below the idle mark but doesn't stall?? I don't know if that means anything :dunno_white:
Since I am doing maintenance (oil, oil filter, checking air filter, bleading brakes, maybe changing brake pads, adjusting choke and throttle,) what else should I check? When do I know to check the valve clearences aside from reaching the 4000 mile mark?
I have a K6 GS500f with 11800 miles. Bought used with 2500 miles.
Thanks Everyone :thumb:
whats your idle set at after the bike is warmed up?
Its set at around 1300-1400 rpms when it's completely warmed up. At first I thought I wasn't warming the bike up long enough but I think it just takes longer because the choke isn't that smooth, which I will address in my maintenance.
Should I just check my valve clearances and clean my carbs and see what happens afterwards?? :dunno_white:
Is cleaning the carbs the same as rebuilding the carbs? Will I have take them apart and rebuild them to clean them anyways?
While I'm at it should I just rejet and put in a drop in K&N?
Any help is usefull!

This can happen if it does not get air as the vacuum drops with rpm. However vacuum is highest ~4-5K, past which it drops too, so you may also be experiencing that with increasing rpm, but not as severely. That should be remedied by checking for a bad/clogged air filter or a bac crank case vent. Too of the valve cover has a hose, and where it bolts to in the valve cover there is a bunch of steel wool. Make sure those are both clean and not clogged. But - read on.
The other situation this can happen in is when you're overfilling your float so much, it is sloshing over into the chamber and drowning the spark. So set the floats back - on 04+ bikes the float tang is super super hard and usually will not bend on its own - unlike 89-00. So it was screwed up by someone more than likely.

Muhahahaha - dropping to below the set idle, then crawling back to idle when you blip the throttle = dead give away sign - you know what - I am gonna check if someone else knows the answer. I'll PM you.
Cool.
Buddha.
