I've been running the Moto-Speed w/moto fuel settings set for the shorter airhorn on mine and it's done great. I plan on having it dyno'd w/the Timbo 450 crank this summer since I got a friend who works at a dealership that just bought one. If anyone lives around Evansville, IN and wants in and to help pay maybe we can meet up and test quads out. Planning on sometime probably in June/July.

Hybrid Dyno chart stockcrank,450piston
I dynoed the hybrid motospeed last year and found a flat spot right around 4000 rpm lean condition but well within safe limits.But yes ALL maps are run at own risk Derno.Got any better ones to offer?I will hit the dyno next week to give stroker and porting a test.Stay tuned.
Only one I can guarantee myself is the blazespeed set-up we used at the 6hr in GA. I took it to the dyno and got as good as a flat line as you could get.
One thing I want to note. I know you know this C27, but your AFR is on the lean side on that last map. The Cannodnales were designed with an optimum afr of 12.5, but I have found that 13 is still safe and operable. Anything above that even though it is good for all other machines I wouldn't guarantee with the dale. Only reason I say that is due to the way these things run hot. Heavier on the fuel will help.
I definitely think we have some good stuff out there for these machines. I just want everyone to be aware of some potential mapping issues as I only have done 2 maps that I would consider safe and just want to make sure we don't add another variable to our equation.

Derno I used the blue combo since it produced more power all last year.Never had a overheating problem.But yes I agree our quads like to run rich.Iceracer has a dyno chart from same dyno.His beat me by 1hp and had a perfectly flat AFR right at 12.5-1 but he also had the MC500.I didnt make any mapping changes which are needed to get a flat AFR.Just flow and offset.This time will be different since I can make mapping changes at the dyno.Still would be nice to have a rider trim setup.
