[QUOTE="bclapham, post: 708607, member: 25565"] angus, calm down!!!:) dont worry about the HP numbers, even the stroked 125-167s have trouble getting past 38HP- they have a load more HP before the peak though- when PC claim their built motors make 40HP i have to wonder how hard they must be to ride (if they even make that power). Elf, are you sure about that needle??? i thought the newer KTMs run the multi taper NOZI type needles-they are richer (steeper) at wide open and you run a two sizes smaller main- i wonder if Erics Specs are for that Needle? i am running a 38mm PWK keihin airstriker on my RM144- i run a 50/50 racegas mix (C12) and my current specs are 58P, #4 slide, DGK (1469) in middle and a 168 main- its finally running nice, albeit a little rich on the lower settings after months of having that rich slide on back order and trying to jet around that. the bike would just bog with any leaner slide! i would seriously consider the stock reeds again- the V-force seem to be reknowned for jetting issues, and i would also check that needle spec.
