Does any of you have a video of a well set up bike and motor, so I can hear the sound of the idling for reference?

Alex, have a listen to this, he has this motor set up like a watch I thought and would be well happy to achieve the same with mine once i get some coils on it and get myself back in the shed.

The whole video is wortha watch if I'm honest, might help, you never know..........

Question to OP, is this one running on std airfilter etc ? Or pods/open ?

I csbt remember if you've changed the specifications.

I am running completely stock. Read enough warnings and scary stories on this forum to just stay with the airbox. Can't say I regret it though!

Have seen this video several times, but actually hadn't thought about that. The engine really seems to run smooth on this one!

K2-K6:
More fact finding than anything in the way of setup....but you could try it with the idle airscrews 1/4 turn out for a few days and then 1/4 turn in (both from where they are now as start point) and give observations as to difference you can feel.
