my bike runs fine when i ride alone, and it also runs fine most of the time when i ride with a passenger
however when i have to stop in a uphill street with a passenger, put in the first gear and go the bike will loose all its power and not respond at all even if i throttle all the way, after a few seconds it will either die or go back to work normal again, the only way to go uphill is to raise the RPM high and slowly release the clutch
my carbs got cleaned and re-synced very recently, spark plugs also cleaned
could it be that the carbs are set for lean and need a more richer mixture?
If everything is working fine, my guess is you need to slip the clutch a bit more as you mentioned, it sounds like you might be pulling the engine down too low for the load :dunno_black:
NOTE: All carburated bikes sold in the USA for street use (DOT) have been lean since the 70's :whisper:

the thing is, this is a normal uphill street, im not trying to climb a mountain or something, i also own a 250cc single cylinder bike (efi) and i can go up in the same street just fine with a passenger, but my gs500 acts terrible in the same street like if im trying to go up using the third gear or something when im using the first gear
Sounds like the angle of the bike is a contributing factor; when riding with a pillion the back end sits even lower.
I'd venture that either you have some water/gunk in the bottom of the float bowls and/or the float level is set too low.
Sounds like a GS500 to me. When I got my 97 GS 14 years ago I was really surprised at how much I had to rev it up and slip the clutch to take off quickly and smoothly, took about 4k rpm and you don't let it bog down you hold the revs and slip the clutch until the bike catches up to the engine. Was even worse on steep up hills taking more revs and more slip to avoid clutch chatter. After my first trip to the mountains I put a 15T front sprocket on to up the revs a bit. Don't know how much you and your passenger weigh but I weighed about 240# then. Your F model is probably more like my current 02 with the newer carbs, takes a little less revs and slipping but the technique is still the same. Work on the clutch slipping while holding the revs and see if it isn't better.
