i've had the bike about a year or so. Has always been reliable and the throttle has never stuck like it is now.
i put on an old fiberglass tank about 2 months ago.
Today was really nice, so i got the bike out and was warming it up. i gave it a little gas, and the throttle didn't return. i had to pull it back (the push / pull cables are a blessing if an when your throttle sticks.)
removed tank, look at cables. they look fine. remove carbs and the still stick without the cables attached. so its for sure not the cables.
i have a suspicion that some contaminate might have went thru the tank and into the carbs, but not sure at all.
i take apart the carbs and clean them. i cleaned the main jet and the needle and the cyl that the slides go up and down in. i get the carbs to where they don't stickf anymore.
Reinstall on the bike, and feels fine. start it up and try to go warm it up again. after it starts to get a little heat, they start to stick again! arghh~!!!
I then decided to call it quits and stop working on it. and now i am here typing. is it common for these cb750 carbs to stick from anything in particular? What are some items i can check? i'm going to remove the tank and carbs again tomorrow and dismantle them one more time. so any advise, or if you have seen this before, what caused/fixed it.
i ended up riding my 1974 cb750 instead today, and that bike decided to start running on 3 cyl after 30 minutes. fucking bikes man. love hate relationship sometimes. i think the 74 is just plugs or something simple.
