Agressive 300? The last tuned one I built was for Paul and he's scared to ride it
The first shakedown was going reasonably ok, revving to 13,500 and lifting the wheel easily in 3rd, but I got a little too carried away with the jetting and we got some detonation 
, so ended up a tad rich just to keep it cool and running.
It'll now rev nicely to 12,500+ and will take full throttle from 2000rpm without a hiccup, right up to full volume.
I'm still building mine. Typical! Why do my bikes always take ten times as long to build? The latest mod was to fit the bigger reed valves from the '92 NF5. Lots of hacking with the chisel, but they're in there snugly now.
I've got a new head design I want to try which should give me more top end power but it looks like I'll need to buy my own CNC lathe to get the job done, and that's not gonna happen this week.
Got a nice lightweight F3 box to throw in it and I've lightened several components in the hope of more mojo. I've modified the R cover to blank off the waterpump and will be running an electric waterpump 'cos that pump must sap at least half a pony.
Oh, and those nice guys at Wiseco made me some specials so hopefully they'll handle the strain.
Electrics are a mix and match of MC21, NF5 and F3.
My software estimates 90+hp at the wheel. We shall see.
If it goes above 90 then I'll switch to alcohol and go for the big 100hp.
Maybe I should eat less cheese before bed......it's giving me funny dreams.
