fat_tony Posted November 9, 2012 Report Share Posted November 9, 2012 im starting this one because i started the other one in the wrong spot and dont know how to fix it ........ok so i got my banshee and it was stock . i have put boysen reeds in it uni foam filter with holes in lid fmf gold pipes pc2 silencers and hogged out the reed cages and ive got 165 compression in both cylinders 19cc domes in chariot head now heres the question ? ive got stock jetting and i have noticed gains with each mod and never had any bogging or overheating and 4 plug chops all looked good. i have bought jets in 290 300 and 320 but have no idea if i should go up to one of them or not ...and please be easy on me as i have searched and read a crapload about jetting its just that the quad seems to run great how it is ................also im at 1400 ft i weigh 330 and ride mostly woods and occasionally drag race my buddies also i mix 40 to 1 with caster 927 or whatever its called and pump gas Quote Link to comment Share on other sites More sharing options...
maskmanLS6 Posted November 9, 2012 Report Share Posted November 9, 2012 First off, your compression is a little high for pump gas. What size jets are in your carbs now? And are you at stock timing, all this comes into play with pump gas. You should be running at least a 280 main i would think, and maybe 27.5 pilots.

fat_tony Posted November 9, 2012 Author Report Share Posted November 9, 2012 (edited) right now its got 300 with stock timing but i have not ridden it yet ...last time i rode it it still had the stock 200 mains in it lol....thats y im so worried everything i read and have been told say it should be at lease 280 and some have said even higher so im scared to ride it till i get some opinions fro some of the more experienced banshee owners and tuners ....i really dont want to blow it up for sure Edited November 9, 2012 by fat_tony Quote Link to comment Share on other sites More sharing options...
maskmanLS6 Posted November 9, 2012 Report Share Posted November 9, 2012 (edited) Stock 200 is too lean for your mods, your probably a touch rich with 300 but thats ok. Ide start at 300 and jet down if needed. Edited November 9, 2012 by maskmanLS6 Quote Link to comment Share on other sites More sharing options...
ntilehman Posted December 30, 2012 Report Share Posted December 30, 2012 Hey man, I got a buddy that has a mild ported stock cylinder bike. He doesn't run aftermarket reeds. His compression is right there with yours. I think it's about 160. He has a +4 timing on pump gas. We ride anywhere from 2600-3200ft. He runs a 320 main and that thing gasses it hard. milk chocolate plugs. I think you are at a good starting point with a 300. Quote Link to comment Share on other sites More sharing options...
