Burgman 650: Yoshimura and Stock Exhaust System Sounds

[Lps2005]

DID YOU HAVE TO rejet anything while installing this exhaust ???

I didn't make any change to the Burgman 650, which is fuel-injected. You hear the backfires more than before on deceleration, but I think that's only because they're louder, not more frequent. A Burger owner in Texas added a Yosh system, and he also added a Power Commander; I'm thinking of doing that the Summer, in conjunction with before and after dyno runs.

Not to much louder than stock so it seems. Feel the difference in HP????

[wspollack]

Not a lot louder riding at a steady speed; much louder as you wind it out. If you omit the baffle, it's like having straight pipes on an H-D.

I plan to do dyno runs of my buddy's stock '08 Exec and my '07 with the Yosh system. I got an increase from 98MPH (stock) to 101MPH after installing the Yosh (all speeds GPS-verified, closed course, professional rider). To get a boost, you probably need a Power Commander or something like installed; I will be looking into that at the dyno shop.

Nope, I don't feel any difference. I may have gained 2 or 3 MPH on the top end, according to my tests, but stop-light drag-racing with my buddy - who owns that '08 Burgman 650 shown in the video - still yields a tie.
