As an Audio Engineer / Sound Recordist by trade I've been curious as to what the quality is on some of the youtube video's I see here and there... Primarily for Audio purposes in diagnosing valve train noise, I don't think they give a good representation of actual sound. I recorded a start-up and a few revs with a Canon G9. The in camera audio sounds thin and raspy to me... Even placing the microphone on the ground where low frequency's can couple... I dunno. I hear a lot more valve train noise in the recording than in reality??? I'm listening with headphones, and now am worried about my bike
Mostly just the high idle and miss...
I only brought it past 4k once and topped the blip at 5500rpm. It's about 15 degrees cooler today than any day since I got the bike in April... I figured more air would lower the idle? It's been on the rich side since day one, I've done no carb tinkering at all, as the idle seemed to settle at around the desired 1100rpm...I think the throttle response is ok... I think it's just the motor not being at terminal operating temps. gotta love Fall anyhowse! any input appreciated. Pls just don't tell me it's got a bad camchain
, as that has been checked.



I'll make a better quality audio recording one of these days...

for now, off to set the idle properly after a warm up ride.

Maybe a bit of valve noise, but definitely not the classic loose cam chain sound.  That would sound more like knocking, almost like a loud diesel engine.

True don't sound so bad i think the valves on mine need alittle adjusting too
That idle is fine. I would actually say perfect. That is where mine is adjusted too.



Edit- That is just my personal preference
