i am currently running dual 34 keihin carbs. it idles but bogs real bad in the mid power range. it has a 392 athena big bore, cool heads, 22cc domes, vforce 4 reeds, billet intake, fmf pipes and silencers, oversized radiators. it is about 25-40 Fahrenheit and about 600-700 feet above sea level. any recommendations on carb setting would be greatly appreciated. thanks for looking
I'm a noob to the world of banshees. I raced super cross as a kid though. (2stroke ofcourse, until everybody started breaking bones) So when my old man said he wanted to start riding as a family again since the grand kids are getting bigger, I figured I'd break down and get a legit quad. (Unlike all the beaters we got sitting around the yard) Anyhow, 2stroke is in my blood. It was quadzilla or a Shee. Easy choice for me. I bought one off Craigslist with rebuilt carbs. Shame on me. Ran great the first two short outings, but then started to bog about mid throttle. Stock everything on bike accept for k&n pods, and f&M pipes, and for some reason the timings advanced. Otherwise pretty stock bike. A 2005. I went to av gas. 100ll. Left it same as previous owner....32:1. Definitely better response with av gas. Same bog mid throttle though. I did some reading on yalls forum and moved the clip on the needle up one. Big difference, but still a tad of a bog at mid throttle till the power band kicks in. Then she flies. Good response on first quarter throttle, and nice idle. ( I like a higher idle) My questions are....its a stock carb, so will I damage the engine if I take the clip to the top? She feels nearly perfect except for that damn little bog period, so would small tuning pilot or idle screw maybe help seeing I moved the clip up one from center already? WOT is smokin fast so main jet is good right? Could there be an air leak or gasket issue going on? There was a reason he rebuilt the carbs... slides look a little worn too. Should I just buy new carbs and be done with it? I want the motor to be on point! I am particular about my equipment and stuff like that. I enjoy the reward after the process of fixing the problem too, but I do need some direction and help though. I know Jack crap about banshees and 2stroke carbs besides what ive learned the last few days reading yalls forum. Any advice woild be greatly appreciated. My old man said get a 4stroke. Hell with that.
550 ft elevation , fmf fatty, boyesen dual stage reeds, maxima 927 40:1 mix, k&n pods. 260 main/30 pilot. jus removed my tors, did the eliminator kit, and installed new dual stage reeds. ordered a 290 main since the reeds richen the main jet but the reeds lean the pilot so it kinda like bogs/farts when i give it gas starting from idle, my air screw are about 1.5 turns out and new idle screws are all the way in far as can go. im thinking its doing this from not enough gas but when i turn the screws in more the idle doesnt sound as nice and tuned as it should, and with my idle screws pulled out any it wont idle by itself without me giving it throttle.. should i go up a size in the pilot jet? P.S.also i got my throttle close to being snappy as possible if i have it with too much play the bike will just start right up bog real quick and die out, my guess is from not enough gas b/c when i rev it high it sounds good braaap but when i low rev it slightly buurps any support is appreciated, Thanks
