Sounds sweet. Nice pipes too.

Seeing it run with no straps on the rear wheel reminded me there is no way you can run the old Manx up on the dyno like that. We left them off once and it smoked up in 4th gear with a 70kg rider astride it, completely different of course being a 500 single...

The blown 500 Kawa twin would smoke a Michelin slick on a 5.5inch marvic....tied down as hard as we could get it.
Now if i could only have kept the water inside it....

There are straps on it.

Starting to look like a proper race bike now. Still a long way to go yet though!

Looking good, love the colour scheme

Here is mine. Now sporting a giant mack truck like radiator.

Currently in the trailer and ready to race.

Do the 300s just boost midrange or are they significant top end improvements?

All depends on what you are comparing them to. But good power everywhere. Most of the gains are in the mid where you need it most. But still way healthy up top. The best they are ever likely to achieve with the over square engine config is a very fat 85 - 87 at the wheel. So basically the closest you will get to a proper GP bike, But it will run happy for a season before a top end rebuild. (if you do it right that is)

Hell,power to weight is very healthy,that car radiator might cost you a few hp

Heres a naked picture of mine,around a 100hrs of fabrication to squeeze the 450 in.
Lots of little teething problems but becoming very rewarding now.

Rich, I remember the NSR's in 250 prod - and how short a time the cranks lasted. And that parts weren't available separately. A new crank was i think about $1250. What's changed ?

Whats changed! Maybe we know a little more now. Also these don't rev past 12k. The cranks seam rather good from my eye. You can buy the bearings again now. But also there are cranks available out of japan from Dogfight racing. Mine has unknown road K's on it and still going strong. I will be ordering a dogfight version when the cash is there. Also the pistons we are using are quite a bit lighter the the very heavy oem 250 versions. The good thing is the bottom end can cope well with the extra togue and topend power. Only bitch is first gear, But that can be fixed.

Love your this thing. Looking forward to seeing it on track next weekend Mr Tidman. The car radiator works on 2 fronts. Puts more weight over the front and stops me hp from escaping when she gets hot. yes it is big. But it works.

We are not quite there with those HP numbers. But very close

There were some bloody good superlite battles yesterday at Hampton. Didn't see you there Leigh? Grant Dalton and I had a slog fest! I wish I new how many times we swapped places. Bloody good racing. I'm uploading photos my old man took tonight, will post a link.
