Proposal to delete rule 24.2.1 - Alcohol based fuel or fuel additives are prohibited

You boys should remember that you all got cleaned up by an 80cc bike in the last 2 grand prix, instead of upping the capacity why not emulate the bike that is clearly superior. ( or are we substituting cubes for ability? )

Well said that man!!!!!

Oh I have the ability all right. If I have a considerably better bike. Or can Knobble him, . . or can blatently cheat in some form of '2nd transponder' caper.

I think i can put together a really solid case for the 4T to go to 205. All based on proven achievable hp pre litre rates for the 2 engine types, 2 stroke and 4 stroke naturally aspirated. So much proven data that it would be impossible to deny. See I don't care who rides what or how fast they ride it. Its not about that. Its about rules for the class that favours 2 strokes so heavily yet the 2 stroke fans / builder / riders are the biggest bunch on bitches that try to change the rules all the time to suite only there interests.

Now thats more like it! Though you could proof read before posting.

Fixed for you!

all motor gp classe's have ended up twice the cc because of been a 4 stroke .. one would think it would be a simple case even though i don't want it to go that way ( just fair)

Keepin it real .....

I've done the maths. Both the 100's and four strokes already benefit from a greater % oversize allowance. Why should the 100's benefit further? If the rule change is accepted the 125's will be short changed a full 3%, or more importantly 2 piston sizes. No problem here with the proposed capacity increase, we all want to draw out the service life of cylinders for as long as possible, but any change should be applied to all.

The idea of 111cc has nought to do with maths.
The idea is to do with using a piston that is freely available and cheap.
the pistons in both 54 and 56 and o's are freely and cheaply available the chose of 50mm and o's are problematic and expensive.$200 plus
Yes destroking is an option...........
If you are implying the 125 AC 2 strokea are short changed consider they never existed in the origional rules.
The 4t have gone from 130-158 and a number of steps over the years.
The reasoning behind this i believe has been sound to allow the 145 and the 150's in which has been a great success.
Rich toungue in check suggested 200cc 4T's I say great idea but only 2 valves and air cooled maybe

Oh rich your are likely right re HP 2t vs 4t but the results of late do not favour the 2t's plus spread of power is also a factor.

Yup I agree, 125 water cooled gp bikes had to be doubled up to 250 foul strokes to keep a similar () performance so I think that's the way to go, 2T up to 125 water cooled and 250 Four stroke , seems very fair, all of course single cylinder and all of course based on a road bike engine.

Good one Scott, - that was so the manufacturers could rub out 2 strokes and replace them with oversize diesels with so much hp they were an irresistible force. Fair was 500cc & you could bring what worked. For most of history that was a 4 stroke.

i like both on the track . l just want what is fair ! 4 stroke fires every second stroke as you no .. but 4 stroke's have got dam good over the years so can get away with less than twice the size . do you have a 2 stroke in your van ? no because 4 strokes for now are the future untill someone comes up with something better .

[mr bucketracer]

if in motor gp1 racing if it was say you can only use 15 letres of fuel a race ( what would be the best ) ???

[F5 Dave]

Thats just a design fault in the 4 stroke firing only half the time. they do get some payback with a higher BMEP due to a cleaner burn, both are compromises. Yes the van is a four stroke, but packaging the expansion chambers would be a problem & the petrol bill would be a bit horrific.

Why on earth would you make racing a fuel economy run? Sounds like an accountants sport.

why not cc when the world is all about fuel emissions ? why do you think 2 strokes are gone burgers
