chunky77 Posted January 5, 2009 Report Posted January 5, 2009 (edited) hoping to get help with something. this is my first banshee so im fairly new to two strokes. my shee is a 99 stock motor with stock carbs no tors. my jetting is 300 mains, with 27.5 pilot , air screw out 2 1/2 turns. im running fmf fattys with powercore silencers k n pods. the problem im having is raw fuel coming out the left side. also left side smokes more than the right. i sync the carbs the best i could using the windows on carbs. any help would be appreciated. this is an excellent site Edited January 5, 2009 by chunky77 Quote
vulvafan537240 Posted January 5, 2009 Report Posted January 5, 2009 what does the left plug look like? replace both plugs. also switch plug wires and see if the problem moves to the right cyl to rule out a spark problem. Quote

firebanshee Posted January 6, 2009 Report Posted January 6, 2009 You could do a compression test just to see if there is an issue there. Quote
someone82 Posted January 6, 2009 Report Posted January 6, 2009 Sounds like that cylinder is running rich. Have you pulled the carbs apart? Cleaned them of any built up gunk. Check your float levels, make sure your needle is strait (bent needles cause excess fuel to flow) and the tip of it isn't damaged, and lastly your air screw is out quite a bit for your jetting. I safe spot is 1.5 turns out, anything over two usually suggests that you need a richer pilot jet, but from what i see you plenty jetting for what your running. Last are your air filters nice and clean? Quote

Is a rebuild needed or can I get a few more rides out of it? Quote

Huey73 Posted January 9, 2009 Report Posted January 9, 2009 I would save myself some money by rebuilding now. Things can only get worse if you keep riding. Quote
