But I won't. What I will do is thank you for your excellent jetting advice. I changed out all the jets on my WR450 for ones ending in 8. Today I discovered I have a completely new bike. No bog , no hesitation, no popping on decel, and the ability to loft the front wheel with little thought or effort. All this with the GYT-R insert. I'm afraid to think how it would run with a good pipe nor do I think I want to know. I had the 70 mile ride of my life today grinning like a baboon the whole time. Oh, and thinking of you. Good job, man.
