Thanks, Kev. But, way ahead of you, as it was included in the original post:
It made a night and day difference on the TT-R as I couldn't get it to do anything more than just idle. Even new, the TT-R wouldn't run right. Cleaned carbeurator, installed a 115 main and the blue needle at the same height as the stock, and it's a night and day difference. When I did the JD kit, I also did the air box mod.
I have kits for the 250F and the 450F (see pic below). I haven't had a chance to put them in yet due to lack of time. I'm also holding out as I want to do more maintenance to both bikes at the same time.
List of other items to put on the 450:
Moose Skid plate
Works Connection Rear caliper guard
Pro-Moto Billet End cap
Bleeder valves for forks
Cycra triple tree and side mount hand guards
Moose Radiator guards
Over flow bottle
I have an overflow bottle and Pro-Moto end cap for the 250F as well to install. I bought them so we could ride trails legally because you can install a spark arrestor in them.
I won't be riding much, if any this winter, as I don't have a way to keep my bike enclosed during transport to keep the road salt off of it. I'll hit up the new indoor MX track once or twice before the snow flies, then that's about it.
No ice racing for me, I don't do cold anymore.
