So what's the two traces? One looks shite and the fuelling is terrible, the other is sweet. Was the crap one the 'before' and the good one the 'after' once the tech had done some tweaking?

65 is really nice.

The lower trace is from when the bike had a scorpion system on it and jetting was way off.
Dynotech have since worked some magic, Also the Titanium Beet system helps as well.

I mean the hover tubes into the tank have been removed.

Wow! What did dynotech do to squeeze another 6bhp out of her? Surely a bit more than just tweaking the jetting and the Beet?

Shame about the hoover pipes though ;) I love 'em!
