I did the bmp velocity can, not obnoxiously loud but a real nice note when you grab a handful. I listened to the powderlite on youtube and it seemed way to loud.
I was told this as well, doesn't de tune but cleans it up. Unfortunately I will never be able to tell the difference, mine was flashed before I've rode it
Just picked mine up today and was told you will a spacer plate, washers or o rings to to tighten the nut enough to secure it, but it's supposed to be super easy
Check your powervalve cables make sure they are set right and move freely. Boondocker box is way better for tuning, leave it lean in that RPM range they are rich from stock there. Get yourself an air fuel gauge if you don't have already. I had this problem when mine was stock and worked it out...
Touch of heat, black thumb nail and working in back and forth it can off. Cleaned the shaft a new clutch in the stage two kit with a helping of copper coat all good
Rode the last 2 days in Revy and areas, so glad I put my tunnel dump can on absolutely no powder bog !!! Good thing for bombs, brothers and buddies................
