leave cams stock unless u port and polish the head.

stock based mods

FCI intake UNI foam filter
Cam mod
thorttle spring mod.
ziptie mod (aka accel pump mod)
big core exhaust (sparks,Dasa,Nmotion) etc.
change gearing
kick start and remove all e start components (less rotational mass)
HC piston kit wiseco/JE/sparks/CP great pistons

ive tryed hmf slipon and hmf full there wasnt any difference between the 2 IMO not worth 250 for a hmf header. i went to a reg core sparks and WOW it will haul some A** now. if you want REAL power send your head to sparks or DASA get it ported then your talking about true HP #'s

Only thing i would sell a sparks for is a HMF Comp series full system..... i had to change my fuel map between a sport series and a Comp series..... much better exhaust.... and has the caps you can make it quiet if you want.
