OK, I got my new woods pipe installed today. It went on easy. Seems to be built well. Fit up well enough. Sounds good. Only slightly louder, but much crisper sounding.
It has a much improved mid, with no loss on top. I auctually seems to come on a few hundred RPM later of the bottom though. No doubt due to my lack of jetting greatness.
Question time.
(*Disclaimer* I have no good area for a plug chop, and test by feel. I am good mechanically, but fairly new to dirt bike carbs. I have a long history of modding PWC) It has 45, 155, 3rd clip in it now. Airbox mod, pipe, silencer only.
At walking speed, in second, if I gap it, it is soft just for a second. (again, it feels like the band starts a bit higher that the stocker). Half throttle and below is quick and clean.
Now, looking over the options, FMF's site says to use the jetting I am now, but to use a R1173K needle in place of my stock R1174K. I'm not sure what this will effect????
My gut says to try one size lower main, (as the site references a 155 or a 152 for my application), but in my ignorance, it seems to me, that a aftermarket pipe would flow better, processing more fuel on the main, not less.......
I only think of the main because, if I'm going slow in second, and want to lift the front quickly of a log or rut, if I gas it too around 1/2 throttle, it seems to pop cleaner and quicker than if I gap it full.
Anyway........ should I try a smaller main first, move the clip position first, or try the new needle first. Thanks for your help. I tried to gather all the info I could before I wrote all the blabber.
