For me, as long as the bike delivers power equivalent to (or slightly better than) stock, I'm good with that. For my type of riding (gravel roads, primitive dirt roads, etc.), more horsepower is somewhat irrelevant -- just more spewed gravel...hehe. I've lost a few pounds and gotten rid of the "camp stove" heat in the process.

His instructions were to mount the new silencer, start the bike when cold and let it idle for 15 minutes with NO throttle input to let the EFI sort itself out.

Here's some close-ups of the Akra unit.


Thanks woods for the info. I'm getting tired of the sky is falling crowd,so its nice to hear some sensible comment. The performance on the 690 is great and like you, I just want to get the heat away from my leg
