thunder alley

6 posts in this topic

I just put on on my 02 WR426F and love it. Easy install and good performance. I also got the SA and had to add a handball size piece of stainles steel wool in front of the diffusser to quiet it a bit. I am very pleased and dont see why the pipe for the 450 would not be the same.

Good Luck :)

I have the TA on my 450, and it runs and sounds bitchen!I am running 155MJ,48 Pilot,clip moved down one position,and the fuel screw about 1 3/4 out. Did nothing with the starter jet(choke jet).It seems to be starting fine right now. I ride anywhere from sea level to 4500 feet.Really haven't had alot of 4500' yet being its winter right now.But I will this spring and summer.Hope this helps!

I will be installing my Thunder Alley tonight and riding the weekened with it.

I will start with MJ 165 and Pilot 48 and work from there, but I think it will be spot on for Sea Level

My bike is Euro spec and comes stock with 160MJ and 48 Pilot

Will report to you guys next week
