Is being baffle free bad for your engine?
 

Ahoy!

Without the baffle in you don't get any back-pressure, apparently.

Would this stress be bad for the engine?

Um, I was speaking to this bloke down the pub yesterday - obviously it'n not somethig that would have occured to me naturally.

yarr!

Without a can is bad for your engine unless its running super rich (what i have herd), the valves start to slam shut very hard and damages the valves & seats.

Even a can without the baffle has back presure.

theres guys and gals done 1000's of miles on here with race cans on and no problems have been reported.

well, as I'm in the clear with the law and I do own that expansive private driveway....glad I used bathroom silicon sealant as opposed to exhaust sealant.

Good advice gained from the forum!

Speakign to teh mechanics down t'bike shop & they reckon that for the daily London comute, leave the baffles in as you'll get better low end. Means little to me. But when you're off on a longer stint or popping over to France remove said baffle.
