Its the threatened 50% tax on high earners...........if I was an MP I'd be putting race fees on expenses

Now there's a thought...I'll go and become an MP and get the tax payer to pay for my racing.....right, better go write a manifesto....actually better still I'll use someone else's and change the words round a bit....no one will notice...:-)

I have just missed the only meeting I intend missing this year, I have booked both days at Snetterton using Sunday as a test day to see if the bike is improved.


I'm sure all those not racing again this year have good reasons.

Is it time to look again at rules for next year and try to find a balance between the performance of class A and class B bikes, so they can be run as one class.
Given the results of the dyno and weight figures maybe we're not too far away as it is.

Let the 750 carb'd bikes run against 620 injecteds, a simple upgrade to the 583's already out there

Quite a bit away for competitive racing between the classes. Sam West was flying and he was 3.5 secs adrift of Shep and Otei. Mixed grids don't bother me at all, its just bikes racing.

Corner speeds are about the same between the 2 classes when someones on board who can do corners.

750 Carbed sounds a good idea to me....or even a 'TP' conversion (now that really does have a ring to it....maybe a show on Men and Motors....hmmmm) if it get's the bike up to 620 speed.

What other changes will a 583 need if the engine is going faster....brakes, forks...anything else?

Conversion of a early 583 engine to bigger valve heads isn't that simple as I understand it, If you have a late 1999 to 2001 583 Monster engine then you can fit the 620 heads and domed pistons, To take it to a full 620 you would need the crank as well.
There is a head on Ebay at the moment for £90, so for a pair of heads, barrels and pistons your probably looking at £250 to £300 providing you have the late engine, by the time you look at adding a crankshaft you may as well be buying a 620 engine (earlier ones are 5 speed later ones 6 speed) prices vary depending on age, mileage etc.
If you could run carbs then you would just need some jetting work done to your old 583 carbs.
The alternative to carbs is fuel injection in one form or another, the original setup with Injector bodies, higher pressure fuel pump, coded clocks, ECU, keys and Harness will set you back a fair bit
There is an alternative of going with a non standard non coded ECU such as a FIM module (not cheap) and you still need the harness for the 5.9M type ECU, throttle bodies, pump etc or you could use a 750SSie ECU with a harness from either the 750SSie/900SSie or the M900ie along with a power commander, pump and throttle bodies

Most people are already runing 40mm pipes so no real cost there.

Then again for those wanting to move into class A there are bikes like Trouty's out there for £2k, you can alternatively buy a standard road 620 for less than that.

Going the carbed 750 route may well have tyre implications as well as the age of the engines and spares availability
