Singh Grooves
« on: November 19, 2016, 03:11:12 PM »
Don, a few years back (+/- 6 years) you did some machine work on the cylinders and head work on my 2005 FLHRCI taking it to 95". The outcome was amazing...nearly 100/100 on pump gas at 10.5:1 with HQ-34 cams.

The big thing you did was Singh grooves in the heads to avoid pre-detonation. I may be heading down that path soon with my 2014 FLHTK and wonder..."Are you still doing Singh Grooves??"

What is the hot setup, in your opinion on these heavy FL bikes for reliability, no knock at the highest CCP, cam recommendation for 20% two up 80% one up to get in the neighborhood of 100/120 tq??

THANKS! Paul
