xr200 and Big Gun Jetting question

Hi, does anybody have any jetting experience with a late model xr200 and the Big Gun pipe (header and can). They suggest a 115mj and 40 pilot with stock position on the needle. I'm going to use the vortex quiet tip though. Any real world experience before I launch into it would be helpful. Thanks! Bill

what altitude?......i got the fmf and just moved to sea level, so post what you find out :)
