99 Banshee idling but doesnt rev up

[janlamarche]

I have a 1999 Banshee 350, and I just pulled everything apart to check the jugs etc. All i did was change a little part that broke inside the shifting mechanism but it wouldnt start after we put it all back together. Finally got it started by jump starting it but it just idles and refuses to rev up at all.

 

The only difference in the gas/air/ignition combo is the packing on the pipes that i changed, but i thought that wouldnt make much of a difference.

 

Is it possible that we changed something in the jetting by just moving those carbs around? or is it a totally different problem.

 

thanks for your imput

Is there a chance you've got a fuel line clogged? Maybe you had some crap in the tank and when you were moving stuff around a little chunky got lodged in a fuel line? I'd pull both fuel lines off the carbs, turn the gas on, and see that it flows freely.

Are the Tors still on? Did you replace the black tube across the carbs? Did you put the slides back in the proper Carb?

[janlamarche]

i'm not sure what the tors are, but i did replace the black tube (which i didn't in the 1st place) but it didn't do anything more with it on, i'll check the fuel line though. and we never touched the slides when we pulled it apart

 

edit: I checked the fuel lines are fine

tors is the throtle override system....usually if a bike will idle but not rev it is parking break or tors related...i have played this game myself and removed tors..

Tors are on the tops of unmodified carbs. Unplug them and remove the plug from the box under the gas tank on the left side.

well I thought it could be the parking brake because one of the wires on the left handle was all screwed up, so i bypassed it completely. So my guess is it isn't the parking brake. The tors would make a lot of sense though. so they're just rev limiters? why are they suddenly acting up?

 

and just to make sure i did the right thing with the parking brake: its part 31 in the the handle switch and lever section of the parts catalogue and its just called "switch". Since it was falling appart i cut the wires short and connected them together, does that make sense?

[janlamarche]

ok well there was a little black box under the gas tank on the left side with wiring which i disconnected, i also disconnected the wires connected to the top of each carburator and there is absolutely no difference. It starts fine and idles fine but when you hit the trottle it just slightly change sounds but doesnt rev up

so,did you cut the wires and wired them together,as in connecting the wires to each other?

yep

[Nutwood 472]

yep

 

 

that might be the problem,if the wires are makeing connection to each other,would'nt that activate the parking brake and not let it rev?

pull ur carbs out and clean em.. have u tried that? when was the last time u checked ur plugs?.i can bet u put the tube in between the carbs but not on the right openings. thats a choke tube./ without it forgot about easy starts and any reving.. start witjh the easy////.... check ur spark plug caps if there still on the plugs or on the boot i had a problem with those a couple times.....

[tom582]

i agree with bebeteck start simple first..if you had to tow it to start it then something could be out carb or fuel i would think.. if you dont find anything fuel or carb related there are diagrams you can find them in fourms on here how to remove tors ...

This is the problem!When you set the parking brake, the switch is closed and the 2 wires are connected activating the park brake rev limiter. Cut the wires apart and it should work. I would recomend removing the green and yellow wire from the bike wire harness completely, it will prevent problems like this from happening in the future.

x2. if you connected them together and it made absolutely no difference, then they were already shorting together in the first place. go to the back of the bike, and snip the green/yellow wire. it should start frvving pretty normal. however, i suggest pulling the carbs and cleaning/rejetting them. make sure the float bowl with the little brass bead on the outside goes bacl on the left (choke) carb, and the little hose goes back on. putting aftermarket pipes on without jetting will melt your motor down.
