Here's the dyno figures from the engine Graham File built for me, It has 59J single ring pistons,gas flowed crankcase, skimmed & balanced flywheel. rebuilt crank with new rods etc, modified stuffers & manifolds to take the 35mm Keihins, kit kip valves. Im running it on leaded petrol with Castrol 747 premix at 30/1
My road bike has the Stan Stevens 300cc conversion, according to the dyno figures for this one it put's out 62Bhp (different dyno) I would say the Graham File engine is the better one, it seem's to be a lot more poweful & revs a lot quicker.
The File tune cost me about £1400.00 (including looking through & cleaning 3 box's of engine bits, stripping 3 cranks & rebuilding 1) on top of this I supplied the pistons which were about £180.00, a crankshaft kit £165.00, Manifold rubbers £39.00,carburetor to airbox rubbers, kip valves, clutch star, kips linkage's & 35mm carbs (brought of Charles) Thought i'd give everyone on here an idea to the of cost to building a "race spec" engine, now "does any one want to buy one of my daughters!!"

Mmm...

You should try putting it on Jame's dyno Krazy-Katt to get a direct comparison with all the other two strokes. If you are racing at Cadwell and go up the A1 you will pass within about 2 miles of his place.

If i'm up that way & there open I will give it a go Mark, the dyno centre I went to was recommended by Graham, they had over 70 different kr1 dyno runs on file dating back to the 90's, the highest read 62.something, this had loads of mods & was also running 40% avgas 40% super unleaded & I think 20% tolune (not sure about this last one)be good to compare it against your readings to see how it measures up

Why no pipes?

If you can keep up with her

Rider needs to move off the bike a bit more, this will allow the same corner speed with less lean angle....

Or same lean angle and more corner speed

Oh yes

That looks like the hairpin at Cadwell - easy to lose the front there....

Dunno if I could keep up with her, in fact, I highly doubt I could get even close.

Then again, if she makes a habit of doing that I just may stand a chance.
