Do you have to re-harden them after you cut the keeper slots?Scott
The custom valves.They will be cut for length, and the keeper grooves cut for proper installed spring height...........
I'm out.I believe that'll be great for a track bike, but, not for my daily rider.Fin.
What kind of lift are you running with those valves, 2.5"?
I take it you are grinding your very own cams for this project? If so, what was the biggest variation as far as the lift/duration between the original cams and new cams? Have you tried any variations to perform better at higher RPMs or are you just focused on making the most out of low end and mid range RPMs?Scottie
