Sounds like a good build bronson. I personally would also bore the carb and try to bump compression up another point or so though...
i will have sredrum bore the carb to 41.5mm. i have thought about bumping the compression to 12:1, it will all come down to what piston comes with the ktm kit. all i know is that i am done buying race gas, so anything over 12.5:1 has a tendancy to detonate during the hot texas summer heat.

Doesn't the 540 add 11.5:1 piston or it's 11:1?
who knows, i think you may be right. i am just going to use the piston that the kit comes with...

thanks to both of you for your feedback!
