Does your SV backfire? - SV650.org

Mine does. When I roll off the throttle at about 3500rpm.
Is this normal and/or friendly for the engine?

Pointy, open can? Normal.

Not had this occur in 6 months -K9 pointy, stock exhaust, no snorkel, restricted ECU.

Normal. If it is doing it excessively, check the small breather hose hasn't popped off under the tank.

LewSpeight · 05-10-13, 04:02 PM

It's nothing excessive. Just sounds cool.
Beowulf can. No baffles. No snorkel. K6.

Any way of making it do it more? It even 'on demand'?
