banshee Running On one side

[Kx_rider]

My buddy just got a banshee and it ran fine for a few days now its only running on the left side. the right side seems to only cut in when the choke is pull full or half out. i know because there is no smoke coming from the left pipe Unless the choke is on. And when the Choke OFF it bogs until u get like 3000+ rpm and then not really any smoke comes from the right pipe. and it back fires after going for a quick ride. We cleaned the carbs already. what should we check for? ( its got the TORS still and a recent top end rebuild only 2 tanks ran through it. )

You have a fuel or spark issue in one cyl. Clean again and verify fuel and spark in BOTH cyls. Then rejet BOTH

Clogged pilot jet in the right side carb.

Ok i swaped coils and It didnt follow the coil. i cleaned the carbs again really good. there was some gunk in the pilot but its super clean now. And it Still Runs the Same.

if you still have the std carbs, they have a tube between both carbs for the choke ( straight rubber hose) if it is not connected weird stuff like this happens. I think the normal choke is on the left and the crossover tube goes to the right so any problem would show on the right side

 

[Kx_rider]

Yes the tube is connected

When you cleaned the pilot jet did you blow air through the orfice? If the pilot jet was clogged, there is a good chance the orfice is also clogged. Remove the pilot jet and the air/fuel screw. Blow compressed air into the pilot jet hole and air should come out of the air/fuel screw hole and the little hole in the carb bore just behind the slide. If air doesn't come out of all of those orfices, you still have a blockage.

yes i sprayed it out with compressed air, every lil part of it, The carbs are flawless clean, factory clean! The jets are 260 mains and 25 pilots and the air screw is 2 turns out. ill get a video of it running with pics of the plugs, soon.

I would recommend running a compression test.

[dirt bike dave]

I agree with the compression test.

Oh, and please verify that you have tried a new spark plug.

it was bad needle n seats

we ended up taking It to a dealer who rebuilt both the carbs internals and over rided the Tors. Cost $500 for dealer fix
