Hi I was wondering if someone can help me pls. I have a 09 Banshee, its done 20 hours, I put a K&N air filter on it Vforce reeds Fattys pipes and a jet kit to match pipes. it was running real good after mods. Then i removed the torrs drilled carby for idle screws did all that was said , read on here use a broom handle ect, did a real good job. took her out and had what seemed a cylinder lazy at high rpm cant get her into 6th gear, just bogs down, backfires on one cylinder between change's brakes down up high rpm. pulled the carbys off cleaned them checked jets blew them out with compressed air reassembled left air cleaner off and got backfires on both cylinders wouldn't idle bogged down trying to rev it. put air cleaner back on and its just one cylinder again up high?? could i have changed the slides mistakenly and would that cause this perhaps? the weird thing is it was fine b4 the torrs removal so its somthing iv done . took off the electrical clip that joins the handbrake just in front of the petrol tank. im a bit lost can anyone think of what this may be. any help will be appreciated
