get an m8 with full slp exhaust, the m1000 is not worth having without mods(fuel box) in my opinion, but unmatched in performance with mods.
Powerclaw is the best mod
HEHE, yeah, my sled won't even get out of it's own way...
Neither did the 08 M1000 we just sold...
Both were/ are turnkey sleds with minimum 20hp over stock with NO BOX. I will never put a bd box on an M1000 again.
You just need to do the RIGHT mods & be careful as you go to run an M1000 without a box.
Crossfire, what altitude are you at?
What you can do to an M1000 depends on two things IMO, altitude & fuel rail PSI, some come a little low, some come a little high. If yours is on the mid to high side you can do a decent amount without a box. If it's not, then you need a fuel reg.
When I was picking up the sled I got from Zollingers in UT last spring, they had a M1000 with a full SW setup with no fuel box, just using a fuel reg. I know they weren't just riding that thing at 11k+, their local spot is as low as 7k if I recall.
My 1000 runs perfect down to 9kish, then it needs some race gas to go below 8500 or so to avoid egts above 1280.
It's all in how you do it.
