ASRBanshee Posted July 17, 2008 Report Posted July 17, 2008 Both of those screws are the airscrews. But if the bike is running lean those screws really wont do shit to help it. What are all the mods done to the bike? Then you need to figure out what jets are in the carbeurator. Also how does the bike run. Quote

Also how does the bike run. i have fmf fattys with power core silencers, cool head with 18cc domes wiseco m series racing pistons boost bottle, the carbs are stock. it ran fine before i put the new pistons in not sure what size the jets are, or even how to tell i ahve 2 sets one for winter and one for summer do you think i need to go bigger with the jets or what as for running when i start it it idles really really high sounds like its going to explode then it backfires and shoots flames.

2/2 many banshees Posted July 17, 2008 Report Posted July 17, 2008 did you put the carb. slides back in the way they came out Quote
Snopczynski Posted July 17, 2008 Report Posted July 17, 2008 did you put the carb. slides back in the way they came out Also what about the choke crossover tube? Quote
█╚98banshee╚█ Posted July 17, 2008 Author Report Posted July 17, 2008 (edited) Also what about the choke crossover tube? i had the carbs off but not apart im pretty sure there on right for flames to be coming out of the exhaust doesnt that have to be a timing issue or am i wrong. i have the black fuel line where it comes to a T all hooked up right and the clear orange tubes are just over flow and breathers right. thats all of the tubes right? i need how to adjust timing. is the stator magnet thing where the timing is. i dont get. i had it running perfect before the pistons but i pulled the stator off to clean it up. these are my two questions is the stator(magnet spinning thing) affecting the timing? do i need to rejet just because i put in new pisstons?

█╚98banshee╚█ Posted July 17, 2008 Author Report Posted July 17, 2008 (edited) alright you got me snopczynski what the hell does the choke crossover tube look like is it blacki can see where it goes fixed the problem with the back firing but it still bogs down when i go full throttle. i give it gas and the left silencer blows a lot of white smoke and the right one blows no smoke and it bogs. what might the problem be? i have both sets of the air screws set the same could it just be a bad plug or what?

05Special Posted July 18, 2008 Report Posted July 18, 2008 you said your running 18cc domes... You may want to check your compression..You may need better octane fuel and have a detonation issue. 18cc domes on pump gas can get ugly Quote
