BANSHEE throttle problems?

[thrill-billy85]

okay....

i went riding the other day and it felt like my throttle got stuck once, but the thumb throttle wasnt the part sticking. didnt think anything of it, went to the car wash after and the thing wouldnt start after i washed it. in my multiple failed attempts to start it, i flooded the shit out of it. took the pipes of and drained them and got it to start (with the help of starting fluid... bad i know, but i was desperate)

 

this thing has the throttle position sensor eliminator caps on the carbs. the switch on the thumb throttle is dis-connected.(if i re-connect it i have to give it enough throttle to de-compress the switch for it to start and idle) i put a new clutch lever assy. and just took the parking brake rev limiter switch off. after getting the thing to start it wouldnt rev. it would idle fine. so i pushed on the parking brake switch and the effin thing revs out with no throttle. the kill switch wont even kill it when this is happening. what will kill it while its revving out is when i open the throttle (i guess it floods it or leans it out too much?). after starting it a few more times this quits happening until IIII hit the throttle a little bit...... then itll keep revving up and ill have to hit the throttle again and itll kill it. after dickin with it more(starting it, trying to rev it, messing with the fuel/air screws, idle, etc) itll start (once again, with i tiny bit of ether) and idle fine (maybe a little high) and rev okay, and come back down, but it takes a while longer than it should...... any ideas?????

Pull your slides out and check them. Every time I ride through water or wash mine the throttle will hang. I was able to pull the filter and see which one was sticking. I was also able to see beads of water on the slide. I put new caps on my carbs but I haven't rode it yet to see if that fixed my problem. I also took emery cloth to it too to make sure there wasn't any blurs on it.

 

Clean your carbs.

ok, so youre thinking its a carb problem, not an electrical problem? that makes sense and definately hope youre right. it just seems strange, cause it progressively getting better, which would steer us away from elec. and towards a burred up needle from careless handling. this would also attest to it being hard as hell to start, especially when there are only 10hrs on the "alledged" rebuild. the guy i bought it from (may have been 20 years old) had also been the guy tuning the carbs, and replacing jets etc. he said he has a #270 main jet in it...... seems kinda big right??? its only bored .020 over... if its bored out at all... i think the kid thought.... "bigger jets, more power". hopefully one day he'll learn about proper air/fuel ratios

BTW what mods do you have? If it's piped 270 may be a little small depending on mods, temp, and elevation. Check the pilots too and see what size they are. I'd say the problem is in your carbs. If I read your comment correctly you must have just bought this bike.
