Heres some footage after the fresh top end and new head

Jake sounds like you have a bit more down low than standard head and squish. Would love to hear it in race strip giving it a bit more rip with the right hand - more go on the pipe.

The sound doesn't do it any justice. That was running mostly in the mid range just below band and coming onto it. I'll try get another where I'm really taking it easy, and one where I'm pinning the guts out of it on a fire trail.

Heres one where I start off taking it really easy and then progress. Should be able to hear all over the rev range. I think theres a bit more to be had in the top end.

The microphone on the gopro really isnt all that accurate.

Sounds and looks good! It seems that with your S3 and the new top end, the bike wants to snap into the power a bit sooner than before.

Whats the plug look like after your ride?

[Jakobi]

Just checked it after washing it this morning. Its still a bit fat right on idle and I think I can cure that with the AS. It will idle but needs some throttle to get back started again. No drama!

The plug looks a bit rich on one side. Nice and tan on the other. I think half a turn out on the AS and a maybe a size leaner on the main and we'll be there. Even then the taco shows max rpm 9970 in the last 140km which isnt too far from what you expect out of a 300.
