Pops
 

No, not talks about my dad but the loud pops that come from the exhaust when on the overrun. This is unburnt fuel yes?

Question,

After putting on my blue flame does it now run too rich and need to have the engine fuelling altered by a boffin or are these 'pops' normal and not a problem, which I hope cause it sounds tasty!

Yes its unburnt fuel, not sure about the fuel mixture, but that shouldn't change, as you haven't altered the fueling to the ECU, no lamba sensors you see....

On my old bike with a race can, it did this all the time on the overrun, but if you are more gentle with the throttle it doesn't usually happen.

in my opinion I wouldn't worry, and yes its very addicted, sounds like a proper bike!

Covered before, it's caused by the PAIR system which is an emmisions reducing measure.
