So I'm in MY shop...phone rings..I answer (I'm good at that customer service stuff...)...and Joe Q skidoo is on the phone, he tells me "his sled ran better with the stock head VS RKT's"... I'm kinda floored at this (I've been selling them since 2001 for a reason) and ask him what sled?... "its an XP" he says...hmmm I think, what jetting are you at??..."I jetted UP 1 size"...OOOPS...I recomended he REJET to 450's and retest...he said " NO WAY, I'll burn down"...I said "If it burns down with 450's I'll buy ya a piston"...
3 days later...phone rings (I answer it AGAIN...)..same dude, different problem...TOO much rpm from the HP he found from the GREAT RKT head thats on his sled...
moral of the story...if OT works on it...it wont work...LOL-BJ
BTW- cutting a 800HO summit head is foolish (its already at .035-.040" and 13.5-1 compression STOCK)..NOW a std 800 or 800HO from a MXZ I cut them all the time as an option...and ramps are adjustable..theres even a MOVIE showing this in another thread somewere...
It's only foolish if your trying to sell a $300. head to someone BabbleJohn...Fact still remains that for $100.00 shaving the head still works and works just fine. LOL
OT
BabbleJohn is tr
