[nogaromill998]

As far as I am concerned I have no truck with cheating. As far as I am aware I have neither broken nor infringed any rules, neither have I gone against the spirit of DesmoDue. To harp on about keeping costs down is just nonsensical when you permit the use of plenty of non standard parts. EVERYTHING in my engine is standard, and within factory tolerance, as it was last year and will be next year. What I have had done is good assembly practice, no more no less.

sorry if you think i am taking the pi55 but this is something i realy dont miss

just goes to show you have to be careful what you say as blueprinting means putting the engine together properly as not many factory engines are put together to within close tolerance.
What nogaro has done is the right thing for the engine as in putting it together properly which some people call blueprinting.

im going to butt out now as my 6pworth is just spent.

I know what you mean Alan, SoT rules were always quite easy to comply with but then again it was far more costl than DD.
What rules a series does have need to be clear, for that to happen we need to close out gray areas

As for blue printing there is the large factory way or the small team way.

Large factory, take 1000 of each component and find a pair that best meets the design spec and use them, no modification required

Small team way, take the pair of items that you have in your engine and modify one so that it matches the other.

Now if you go some where in between and start with several items and get them matched up as best as possible without modification then thats fine by DD rules but if modifications are carried out then rules are being broken.

What would be next porting/flowing heads so that both heads flow exactly the same, anybody got the factory figure for the CFM of a 620 cylinder head, I know the rules say no material can be added or removed but surely its just good practice and therefore I should be allowed to do it

after all if it wasnt for dd then we wouldnt be doing what we do now in running in a great club which has televised racing all season

A month? Is there a class for these?

My understanding of the rules is that no mods are allowed to the crank, and as far as I can see balancing a crank is merely good practice, not cheating in anyway, as I have already said, it is absolutely bog standard in everyway, with no performance enhancement inferred or gained from just putting the thing together properly. I handed them a crank, 3 sets of rods and pistons and gudgeon pins, circlips piston rings etc and told them to balance the thing.

That's what I understand. It's like putting balancing weights to the wheels then

Very good analogy Alex, you are adding material there but it gives no performance advantage, just makes the wheel run correctly.

but we all know 748/916 wheels are used......I think some common sense needs to prevail here.

Quite right re the last sentence

For example the same front wheel (501.2.069.1AB) is fitted to both MY03 620 and 750 Monsters.
So if I took a front wheel off a 750Monster from another year and used it, would it be illegal?

Mind you, my bike has a 900ss frame, Mhe900e forks, a 750ss rear wheel and an ST2 front wheel so I might as well be banned now and save on all the race entries...

Stick bit's of lead on the crank

count me in.. i can crash them just as well as a DD bike

Ultimately the rules have been the same on balancing (that it is not allowed) since the start of the series and from memory we have only had one motor blow up (Ali's fire in year 1). To a certain extent balancing, expecially on the Class B engines is not worth the expense as they do not rev that high anyway and are somewhat overengineered for 52bhp.
