Exhaust Popping. - SV650.org

07-09-10, 08:35 PM

I have an Art can on my curvy SV and it pops a bit between 4000 and 5000 revs. It's generally in 2nd or 3rd gear, and normally when I've revved the bike up to say 7000 and let go of the throttle, it'll pop as the revs drop back through the range, and below 4000 there's no problem.

I'm very new to bikes so I just wanted to find out whether this is something I should be concerned about or whether it's something as simple as the type of can I have.

Thanks

WB

You may have an exhaust leak, in which case 'popping' on the over-run is quite common.

I have same can it will pop like mad if you let it idle at about 2000 revs. But as what is happening to you mine did the same then one day just stopped

popping on idle normally means a carb balance is in order id think

It doesn't pop on idle, just as the revs drop through the 5k to 4k range

If it's only happening as you're coming back down the revs then it's just a bit of unburnt fuel passing through the system and combusting as it contacts the super hot exhaust gasses - nothing to worry about whatsoever

enjoy it

(also checkout the sound of world rally cars at red line or as they come down the revs

As I recently found out, it could be due to one of the pipes to the carbs not being properly plugged (The front one often gets a makeshift pipe added as a result of a carb balance). Same profile of when it's popping as I had, though mine had trouble idling, too.

Enjoy it.
