Re: Jetting with HMF exhaust?

Anyone know the correct jet sizes for the HMF exhaust on the 250EX? I am keeping the airbox lid on if this matters. I am also running a Big Gun rev box.
I had this exhaust installed at Motion Enterprises in South Jersey and I must say these people are complete **** tards. Not only did they get high temp silicon all over the head of my engine, they broke the clamp and just put a hose clamp on and took months to get the replacement. They said they jetted it and stopped the backfiring it was doing since I bought it from them but it still does it out in the heat and I just swear they never touched the jetting, but I can't confirm because I am unable to tear it all apart myself at this time (no tools) and don't know the original size to begin with.
I've been fighting with them for months to fix it and they refuse (and I spent over $10,000 there on this quad) and they still haven't done a thing. Now I have to suck it up and get it done myself.. I just don't know what I should use.
10,000!!!!!!!
first, Did you even look in the 250ex Performance FAQ?? it's right there in front of you and even breaks it down for you with jetting recommendations!
I'm not trying to be mean, but please, before you make a thread at least take a few seconds to look.
