cheeta Posted December 4, 2008 Report Share Posted December 4, 2008 (edited) im kinda new to banshee's and this kinda got me stumped. my bike started out with a single carb, unknown pipes, k&n filter with holes cut in the lid, and stock reeds. I bought my buddies fmf gnarly pipes and powercore 2 silencers, boyeson reeds and stock carbs that where jetted for his bike with the pipes and reeds i bought from him. neither one of our bikes are bored or ported but he had one of those adjustable stator plates(setting unknown) i also dont know what kind of filter he was running. i assumed i could just bolt it up and go but now my bike isn't running right. it takes like 100 kicks to get started and once it's started i have to feather the gas to get it to rev, if i just give it a shot of gas from idleing it just dies out and sucks super hard through the airfilter(sounds like a honda civic with a crazy intake)i even tried taking the filter off but it still does it. we are at sea level. i dont even know where to start like do i need a smaller jet? does anyone know what size jet i should be running? i am gonna chech tommorow and see what size is in it and see where the needle clip is at(any suggestions?) the snow is about to fly and i wanna be ready oh yeah other than from an idle it works exelent Edited December 4, 2008 by cheeta Quote Link to comment Share on other sites More sharing options...
LS1Inferno Posted December 4, 2008 Report Share Posted December 4, 2008 well what kind of filter is it? and do you still have tors. it sounds like the jetting is WAYYYY off or there is an electical issue. take the bottom of the carbs off and let us know what jetting you have it should be around a 320 main at sea level i belive Quote Link to comment Share on other sites More sharing options...

Check and see if you got the slides put back in the correct side. I have seen a few people take off the carbs and when they put them back on the switched the slides and that will make them hard to start and they run like crap on the bottom. With FMF pipes and a in box k&n you should be running around a 290 to 300 main jet. Quote Link to comment Share on other sites More sharing options...
cheeta Posted December 5, 2008 Author Report Share Posted December 5, 2008 yeah i looked today and it has 260's in it for mains and i could not see the pilot jet. i adjusted the air screws to 1 1/2 and it seemed to help a bit but its still not workin the best Quote Link to comment Share on other sites More sharing options...

Make sure they are in the carbs so when you look at them from the back of the carbs that the rounded part of the slide is facing towards the back. One other question i was reading through your posting and to make sure are you saying it runs good once you get it reved up? Quote Link to comment Share on other sites More sharing options...

One other question i was reading through your posting and to make sure are you saying it runs good once you get it reved up? i double checked the slides and they are fine and yeah once i get it up past idle it works fine but if i try to give it a shot of gas from an idle it just bogs out Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted December 5, 2008 Report Share Posted December 5, 2008 Choke balance tube on? Slides backwards? Quote Link to comment Share on other sites More sharing options...
cheeta Posted December 5, 2008 Author Report Share Posted December 5, 2008 Choke balance tube on? Slides backwards? slides are in right(they have been tripple checked) and the choke hose is on Quote Link to comment Share on other sites More sharing options...
BUILDER Posted December 5, 2008 Report Share Posted December 5, 2008 slides are in right(they have been tripple checked) and the choke hose is on Just checking have you unplugged the throttle override box on the frame? I know you said the wires were cut to the TORS but if you have not unplugged the box also some times that will do wiered things. I would also wonder if some one has put smaller pilot jets in those carb. Does it start easier once you have got it started and warmed up?

Does it start easier once you have got it started and warmed up? yeah once its warmed up it starts easier. and i never looked at the box because my bike ran fine with the one carb so i didn't look to see if the box is still plugged in or not but i am gonna check right now Quote Link to comment Share on other sites More sharing options...
AKheathen Posted December 5, 2008 Report Share Posted December 5, 2008 (edited) ok, sounds lean 0ff-idle. set your airscrews where it idles the highest, sync your carbs, and try moovin your needles 1 knotch away from the blunt end. when the pilot circut is right, it will want to idle with the airscrews between 1 and 2 turns out. that sucking air sound is the lean hesitation, and lean will make it near impossible to start as well. probably a good idea to give them a good cleaning too. and there doesn't sound like any problem with throttle overrun circut. it would either not idle, or only idle.

If it starts easier when it is warm you have a lean condition for sure. Not to disagree with the guy before me but i have seen some really odd problem with the uverride box on these things. If it is still plugged in i would unplug it just because you dont want it in the system. In the procces of taking the carbs from your buddies bike to yours you may have got some crap in the pilot jets and you may need to clean you carbs out good. If the pilot jets are plugged they will not start well at all. Quote Link to comment Share on other sites More sharing options...
cheeta Posted December 6, 2008 Author Report Share Posted December 6, 2008 (edited) i am gonna take my carbs off and clean them. does any one wanna give me a quick rundown how to sync my carbs with the tors still on and without the tool? it would be appreiciated. i watched the video of how to do it with the tool and the tors off but couldn't find anything on the oldschool way and with the tors on Edited December 6, 2008 by cheeta Quote Link to comment Share on other sites More sharing options...
cheeta Posted December 8, 2008 Author Report Share Posted December 8, 2008 alright i just stripped my carbs right down and cleaned them and sync'd them when i put them back together. i looked at the pilot jets and it had 2.8 written on it. is that a good size? it is still bogging out from an idle and will not start when it is cold and runs fine when its warm(except from an idle. i need to know what size pilot jet to run and should i try a set of 280 jets?
