I have had my banshee for three years now and have not done a top end on it. Since I have a fat tax refund coming I want to throw in about $1,500 into the motor. I do 80% sand riding with occasional line ups (at glamis, pismo and hopefully oregon this year) and 20 % tight trails and dirt hill climbs around local parks. I've talked to Kevin at HJR about a 4 mil but he recommends a mx port with the build...? I would like other people's opinions.
Would a dune port not be manageable in trail riding? Also, how much will a mx port hold me back on an occasional drag race going up Oldsmobile Hill in Glamis?
Does anyone have dyno charts that they can send me to compare power curves and max power ratings for these set ups.
I have the following upgrades:
single K&N filter going to two stock carbs no airbox
toomey manifold
boost bottle
v force reeds
cool head
full toomey t-5 exhaust
barnett clutch with HD springs (ouch)
pancake bearing
and painted the original front bumper matte black for an additional 15 hp (j/k)
i dont think previous owner did anything to the cylinders (like porting)
Next weeks shopping list
-adjustable timing plate
-Hinson Billet basket with cut gears
-and new LED light set up
