DannysZ28 Posted March 23, 2009 Report Share Posted March 23, 2009 I just bought an 02 Banshee and it has a few mods and i was wondering what else would help my set up the most. It has a 4 mil crank, port and polished, fmf pipes, k@n filters, jetted and has stock head and carbs with about 140lbs of compression. I am running 17-41 gearing. I have run a 700 raptor that had a pipe and power commander. He jumps me out the hole about 3 lengths and by the time i hit third i am coming back around him and can toy with him on top end. Just thought i would give you guys some idea of how it runs. Im not sure if thats really good or not but it sure feels like its hauling ass. I had a modded banshee back in the mid 90s but there were not near as many 4 strokes with any power to run against back then. Quote Link to comment Share on other sites More sharing options...

3 stroke Posted March 23, 2009 Report Share Posted March 23, 2009 most stroked shees are running a 14 41 to 43 gearing. 17 seems a bit high for a banshee that has 6 gears :biggrin: Quote Link to comment Share on other sites More sharing options...
DannysZ28 Posted March 23, 2009 Author Report Share Posted March 23, 2009 I thought the same thing. I bought it with these gears on it. Even with it geared that high, it still has no problem pulling the wheels off the ground in 4th. Quote Link to comment Share on other sites More sharing options...
tony cub Posted March 23, 2009 Report Share Posted March 23, 2009 (edited) most stroked shees are running a 14 41 to 43 gearing. 17 seems a bit high for a banshee that has 6 gears :biggrin: i run a 17 on my trail bike w/about the same mods..

I had a modded banshee back in the mid 90s but there were not near as many 4 strokes with any power to run against back then. I would def get a timing advance plate, set it at +4........get u a coolhead and up the compression, i cant reccomend a dome size as im not sure of ur elevation but ur head could be shaved with 140lbs of compression, but u can go to near 160lbs with the need for race fuel.... with 17 41 gearing u should be able to toy with him on top end hahah i would drop down to stock 14 if it were me to give u a little more ass out the hole.... but depending on ur riding environment if u have the room to run a 17 stick with it..... ditch the fmfs for some cpi inframes or toomey T5s....im sure many of the more experienced gurus here will chime in! welcome to the forums Quote Link to comment Share on other sites More sharing options...
AKheathen Posted March 23, 2009 Report Share Posted March 23, 2009 first things first, what kind of ridding do you do, and what kind of porting do you have? Quote Link to comment Share on other sites More sharing options...
DannysZ28 Posted March 23, 2009 Author Report Share Posted March 23, 2009 I think it more of a home ported (not professionally done). I do mostly trail with alot of 1/8 mile drags in fields and i live along the coast of NC as for the elevation. Quote Link to comment Share on other sites More sharing options...

DannysZ28 Posted March 24, 2009 Author Report Share Posted March 24, 2009 I am running the fatty pipes. I think i will go with the 15 up front. I talked to the guy that ported them and he said the jugs were opened up a good bit. I think i am just going to run it ported like this for now until its time to freshen up the top end.

jbooker82 Posted March 24, 2009 Report Share Posted March 24, 2009 Home ported 4 mill jugs? I would be looking for another pair of jugs and get them ported with the style of port job that matchs how you ride. Then you can just swap the top end with no down time waiting for your only pair of jugs to return from the builder. There is a lot of power to be found by a good port job. There is a lot of power to be lost too by some one that doenst know what they are doing. Is there a spacer plate between the cylinders and top case or a thick 2mm head gasket? Or are you running a cool head with cut stroker domes? josh Quote Link to comment Share on other sites More sharing options...
DannysZ28 Posted March 24, 2009 Author Report Share Posted March 24, 2009 thats a good idea about the cylinders. It looks to be a thich head gasket. On a 4 mil crank, the piston only comes 2mm out of the top of the jug right? Quote Link to comment Share on other sites More sharing options...
