Problem!

[jokmm]

Hey, I have a Honda CB125 Chinese copy bike, and for some strange reason every time I roll off the throttle, there's a really loud shotgun resembling pop from the exhaust. I've previously had issues with it randomly refusing to idle which I still don't know about but it's kinda fixed. I've put some Redex fuel system cleaner in to see if anything's blocked but in the meantime it continues to pop. I had the exhaust off the other day and there's a decent flame coming out of the exhaust when you roll off the throttle. Anyone got any ideas?

Thanks

my money's on an exhaust air leak. Headers?

Ive got a CG Replica kinda bike.
I had a problem with the exhaust studs kept snapping, causing it to be loud, and backfire alot, mainly on no throttle slowing in gear. Would pop and burble like mad.
As has been said, check for exhaust blowing.

I love the sound of a bike popping on the over-run, its exactly the reason i'm not repairing the crack in my pipe, infact I deliberatly accelorate just to come of the throttle and here the burble.

Made of win - enjoy it

haha, you're right there, it sounds awesome, I just hate to think what passers by think when you ride past and the next thing there's a massive shotgun
