locogato11283 Posted December 29, 2008 Report Share Posted December 29, 2008 need advise for built stock 2008 banshee engine I need top speed and high end and wheelie maker too... I need the top for 91 octane fuel exhaust: reed valve: cylinder/dome: carb/jetting: fire timinig: rear/front sprocket: any suggestion and opinion is welcome i would suggest some dune/woods porting. itll give you a good bottom end, but youll also be able to pull taller gearing if you want. pipes: toomey t5 reeds: v force head: NOSS head, but stock will also work carbs: stock will be fine timing: gonna have to stay stock unless you wanna run higher octane fuel sprockets: depends on terrain, rider weight, mods, tires... builder: FAST!!!

jbooker82 Posted December 29, 2008 Report Share Posted December 29, 2008 If you want to hand it to them then go this route. 4mill Stroker Crank Dune Port CPI Small Bore Pipes PWK 33's with a Boss Intake V Force 3's with Cascades Stuffers Custome Noss Machine Domes for Pump Fuel and the 4 mill stroker crank +4 Timing Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted December 29, 2008 Report Share Posted December 29, 2008 You can get away with @ +4 on the timing and around 150psi of static compression on 91 octane. I would need to know your elevation to make a recommendation on the dome size to get you there. As far as your pipes ect, what type of riding do you use it for? ie: fast trails, technical trails, dunes, open fields ect. FMF fatties are a decent midrange pipe, the gnarly's are a good low end pipe. If you're wanting more power in the top end you could consider some t-5's or cpi's. Your portwork is all going to depend on the pipe and type of riding. Quote Link to comment Share on other sites More sharing options...
3SGTE Posted December 29, 2008 Author Report Share Posted December 29, 2008 my elavation is between 150ft and 1200ft ... I ride in fast wood trail Quote Link to comment Share on other sites More sharing options...
Wildcardracing Posted December 29, 2008 Report Share Posted December 29, 2008 21cc domes should do nicely. I would probably recommend and aggressive trail type port matched to some Pro-Circuits or FMF Fatties. +4 timing and ported stock reed cages with boyesen dual stage reeds. A pro flo filter setup with a k&n if it gets wet where you ride or dual pods if it's dry. If you want even more power then you could step up to a 4mm stroker and some 22cc stroker domes with all the same mods mentioned earlier. A couple of good insurance type mods would be a billet water pump impellor and a pancake bearing clutch adjuster. And if you're not opposed to splitting the cases I would highly recommend having your crankshaft trued and welded. Quote Link to comment Share on other sites More sharing options...
