i would think ya should be around a 280 or 290 with pc's and uni clamp ons .... depending on ur elevation. im at 800ft elv. and i run 280's @ 75deg. with fatty's, k&n, no lid (wife's banshee)
if ya really want some awesome bottom end dynpport 2n1 , trinity 35mm cv 2n1 , a good woods/mx port , Noss or Prodesign head 18cc domes , proflow w/K&N , and ditch the airbox lid and snorkel !! !
im thinkin bout goin with a 35mm trinity 2in1 cv set up we run oval and flat dirt gp course type riding. no tight trails just fast open trails and will it work with cpi's on the oval??
lol i have a friend i ride with that runs bills pipes and my wife runs fatty's on her stocl shee and well she can rip on him everywhere in the powerband ... but then i believe the fatty is the best all around pipe out there .... theyre just build like sh*t as far as quality goes
ive been runnin vf2's for a couple seasons now and the only mishap theyve had was i had to replace the petals on one cage .. lol so i did em both instead of just replacing the petals on one cage
my 03 seems to have a point that it cackels "sputters" where its coming into the pipes. plugs are burning fine so i assumme its allgood, O and it runs like a striped azzed ape with his balls on fire LOL
hours are irrelevant to a point, keep track of your motor by doing scheduled compression and leakdown testing. that will keep you ontop of your motor condition
will prolly get some bashing here but OWELL i had some pro x in my 98 but as some said theyre crapola ... i gots wiescos in it now "good pistons" ... im runnin the vito's forged pistons in my 03 it gets totally abused on the oval i got major hours on it and theyre still in great shape .. just something else for ya to look into i guess .. any feedback on the vito's stuff would be appreciated cause im always lookin for somemore HP LOL let the vito's bashin begin
