sl0wp0ke Posted March 30, 2013 Report Share Posted March 30, 2013 I have a 98 banshee that is new to me. I am running a stock air box, with k&N filter and holes cut in the lid. It has fmf exhaust, vforce 3 valves, and is supose to be bored out to a 392. It has 30mm ysn carbs on it. When I drive the bike out of the power band it seems to be very boggy(makes little power). Once I get back into the power band and give it a few extra shots of gas it seems to come out of it and work fine. I do not have a lot of experience reading plugs but they seem to be wet . Do you think the bike could be jetted to rich? We pulled the jets out of the carbs but they sizes on them are worn off. What size jets should I buy to get started, and fine tune from there? Does anyone else think the problem could be something else? Quote Link to comment Share on other sites More sharing options...
sl0wp0ke Posted March 30, 2013 Author Report Share Posted March 30, 2013 I guess I should add that I live very close to sea level. Quote Link to comment Share on other sites More sharing options...
RadarRacing Posted March 30, 2013 Report Share Posted March 30, 2013 Honestly ditch those ysn carbs asap and put stockers or something else on it. YSN carbs are a very poor chinese knockoff of pwks. I am not bashing them cuz they are chinese and not knocking you or your bike at all. Just trying to help you. Those were carbs used on some stock 90cc quads and we never had anything but leaks or problems with them. Quote Link to comment Share on other sites More sharing options...

sl0wp0ke Posted April 1, 2013 Author Report Share Posted April 1, 2013 What size jets should I use in the carbs? I want a good starting point. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted April 9, 2013 Report Share Posted April 9, 2013 What size jets should I use in the carbs? I want a good starting point. So which carbs you going to use? Quote Link to comment Share on other sites More sharing options...
Launchpad Posted April 11, 2013 Report Share Posted April 11, 2013 A good starting point is to get some new carbs before those things cause you to mess something up Quote Link to comment Share on other sites More sharing options...
J-Madd Posted April 12, 2013 Report Share Posted April 12, 2013 Regardless of brand of carbs, 30 mm is too big. Too little velocity. I used to run OKO 30 mm on a stocker and had similar issues. Quote Link to comment Share on other sites More sharing options...
