Just for referance yesterday I took my well built 02 CR250 husky out for a rip. Has a Lectron on it of course. I just installed a C2 brand pipe on it. Under load it had a bit of a ping it never had. Some of this might have been from weak fuel due to sitting a few months. But I was able to dial the PJ richer and eliminate the ping in about 10 seconds. Brilliant. I did also end up going 1/4th turn richer on the rod which restored some of the bottom end I lost pitting that pipe on. Now the bike runs harder than ever and has a powerband to die for. Such a wonderful squirt of liquid power. Yep, love my Lectron.
