got my hmf exhaust

[rap169]

well i got my hmf in black today. Its a omplete system. I pulled the air box lid and put in a 180. ITs pretty good, but when my sparks filer comes in, would i have to go bigger? Will the sparks flow that much more air than the stock filter? Any suggestions on size?
Oh ya, this exhaust is great and the power is right there. Highly reccomended.

im not exactly sure, but i doubt just a filter is going to flow enuff air to require you to go up a jet.

I'm running HMF with K&N, no lid and the 180 main is the only jetting I've done. No problems.

anybody run the hrc needle? Does it help any?

I have heard that the hrc needle helps, not really sure I have the hrc kit installed and it runs fine.

i have the hrc kit in my bike with the k&n filter. i am running the 185 main jet that came with the hrc kit. i turned my fuel/air screw out three and quarter of a turn out. it seems to run fine. i was thinking about trying a 190 main jet in there to see if it helps any. if anyone has tried this stuff lep me know if i am going the right direction going bigger in jet size.
