POORBOY350 Posted July 27, 2009 Report Share Posted July 27, 2009 im wantin to get all the power i can sqeeze outta my 4mil cub. its a beast now but i've never had it tuned or anything. it has 35mm pwk's, vforce 3's, 68mm bore 4mil 421 cub, 20cc domes, cool head, cpi inframes, +4 timing, straight cut gears, oversize radiator, lockup clutch, basically i mean theres much more. but im just wondering what i can tweak on a lil bit to get some more hp out of it. usually run 100-111 octane gas. i know i need a longer swingarm that will be the next thing soon! but ill figure out how to keep it on the ground i just wanna know some things i could do to get more HP outta my motor. thanks...

bbcmudtruck Posted July 27, 2009 Report Share Posted July 27, 2009 Have you tried playing with the gearing? I just bumped up a tooth on the front and its night and day different. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted July 27, 2009 Report Share Posted July 27, 2009 Ditch the race gas. Go to methanol and jack your compression and timing up and it will blow your mind the difference between race gas and meth. If your crank is good and solid, put some 18's in the head and go to like 7-9degrees of timing and get your carbs converted for meth.

POORBOY350 Posted July 27, 2009 Author Report Share Posted July 27, 2009 My main problem is its topping out too fast. i've tried a 17tooth front sprocket im runnin 15/40 now. i need it a lil higher and i think that would help alot. but i also want to get more power on the top end to. like if addin more timing or maybe just getting it tuned right would help idk this is only my second banshee. its definately toppin out too fast need more top end. 17 tooth was too big. what can i do? it just doesnt run like a cub should!!! i need some help! should i go up a tooth on front or 3 on back or what yal think???

TurboBanshee420 Posted July 27, 2009 Report Share Posted July 27, 2009 have it set-up for meth, and run 15% nitromethane, retard the timing to stock, and keep the big domes on and hang on!...lol Quote Link to comment Share on other sites More sharing options...
okbeast Posted July 27, 2009 Report Share Posted July 27, 2009 It probably needs to be tuned. With what you have, and that gearing it should pull very hard. Quote Link to comment Share on other sites More sharing options...
