Hey guys I was wanting everyone with a Big gun to post wht they think and a few other points.

1) Carb Jets
2) What air box mods
3) Noticable difference
4) easily damaged in high air rough landings or
rear collisions.

thanks Guys

 

Bought the complete unit. Seems to have made a difference in the available torque and HP in the low to mid-range. Nothing fantastic, but very noticable. I can't really tell a difference on the high RPM end. I'm running a K&N air filter, with Outerwear cover, no airbox lid, #42 pilot, and a #165 main, airscrew 3 turns out. Seems to be jetted about right for 1-2K altitude desert riding.

 

I bought the whole system. Nice fit and finish. The jet kit and air box made more difference than the pipe. I am running the 155 main and 42 pilot according to Big Gun's specs. Much louder than stock. Those I talked to said the FMF core 4 sq. was nearly as loud as the old core 4...
