It's been nearly 2 years and 15K miles since we built and tuned this one, KR brought it in for some off season routine maintenance and I couldn't resist a recheck/tune on the drum and it is still right where it was when it left here in January of 2016..

Always, a pleasure to read these kinds of posts, sort of like a follow up on how a dedicated a shop is in customer service.  Keep up the good work Darren !!  I hope I can ride down someday to visit you and possible have you work some magic on my bike.  Happy Holidays..

Bike seems nice to ride, great build and tune !

The graph seems pretty close to the CR570-2, but with higher numbers. Is this due to the ported heads, comp difference or just the cam itself ?

The heads are what add the extra power. The 575's are more suited for a build like this than the 570's which work great with stock heads and compression.

I've looked at this build enough times wondering, "what if" :nix:... and then I say to myself "why" :slap:, when it already is the build that I had in mind. I figured if I had a build at 105hp-115tq, crossing 100tq at 2250 and holding it out to 5250...this covers it well! Its been mentioned as a "mouse cam"...but a mouse cam that roared! Definitely a tune I'd be proud of if I was its author...!

Nice build & tune,
value build been mentioned here, would it not have been value to go 96" to 107" with those heads, & still work under the threshold of TB/inj ?
