Well have we all?? Had a think about the "new" rules for 2007 or when ever they start to take place? What rules you say?? Well the rules that bring back motor size to what the maker made them!! e.g. 650cc and 500cc Triumphs, 500cc, 600, 650cc Norton twins and all the others.
I see that the commissioners have banned, EFI for P4/P5. Who knew that was on the books? How many other things do we NOT know about?? WHO runs OUR sport, the old story!!
Any how the TZ350G is up and running, ready for the race track thanks to Bert Small Coil Rewinds for fixing the black box and at a cheep price good on you Bert..
T500's running, only need a new set of pistons for the short stroke 500 triton now. See I have been playing with motorcycles who said I had given away the sport?? And are LOG BOOKS in for 2002?? Or only state titles what ever??

Also the log books appear to be enforced in 2003, not 2002.
However sent my application to MA at least 6 weeks ago along with a cheque and I havent received a reply let alone a log book.

Trevor,
Looks like the way that MA prefer to operate, by keeping it's members in the dark. Not good if it is six weeks since you sent off for you log book. Have they cashed your cheque? If they have then they should pull their finger out of that pile of mushroom food and start to support it's members.
I am willing to allow MA to use this site to keep members informed and updated on stuff. As you know it isn't that hard to use the site.

MA,
The offers there for your organization to use this site to keep your members informed. You can logon and let us all know, or you can send me an e-mail and decline the offer if you want, but it would be a backward step for MA and Classic Motorcycling across Australia.
It is your choice, support your members or tell them to get stuffed by not taking the offer that i have offered.
Regards,
David

| I have had discussions with Committee members, on this point. There are no plans to change the rule to manufactures capacity. It was discussed but not supportted. EFI is ok if it is mechanically operated as it was in the period, but electronic stuff was not readily available and so it is not permissible. |

I also believe this is correct John. I asked the question on this site about sleeving a 175 bantam back to 125cc and was told that this would not be acceptable.
I contacted MA and was told it was perfectly acceptable and the bike would be eligable to race in period three as the motor is a 3 speeder. |

RonG,
I beleive it was this topic: You must be logged in to see this link. and the Bantam was produced as a 175cc when manufactured, but you wanted to change it to a 125cc so you could quote:

Would this not be acceptable as it was manufactured as a 175cc and I would be pretty sure that the 175cc sleeved back to a 125cc machine was not raced back in the era.
Correct me if I am wrong. I just would of thought that the faster they were back then, the better it was. |

It was common in period 3 years for riders to sleeve bikes back to a smaller capacity. I am not sure but I believe that the Hunter Piccaniny that George Huse ran was originally a 175 but was sleeved back to 125cc. Jack and Kel Curruthers ran 250cc Manx Nortons in the late 50s and early sixties. The original GMS (Geoff Monty Special) was a 350 Bsa Gold Star stroked back to 250cc.
The intention is to run a bantam as a 125 and not have to compete against 250's. The reason for using either 150cc or 175cc bantam motors and sleeving them back is that it is not economically prudent to try and source 52mil pistons that have reasonable rings and an adequate skirt length to cover the exhaust port at TDC.
There are plenty of 54 mil pistons that will work but with a 58 mil stroke' but it places the motor greater than 5% over the 125cc limit.
The best way to run a Bantam nowdays is as a 54 x 54 motor and it is a waste of time using an early motor because you have no oversize options because of the thinness of the sleeve to start off with.

| my 500 cc triumph is a destroked 650 motor built in 1957 and raced at that time so should be legal it uses 650 crankcases, barrell and heads and will spin to 10500rpm! |

I don't think HRR 082 was concerned with undersized motors. In any case I've been assured by certain parties that Rule HRR082 didn't 'get a gurnsey' at MA. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxI can also remember a friend of Allen Greening's showing me a 350 BSA racing bike back in the late fifties which was a destroked 500. (A really good way to go). Destroked motors definitely existed, but I can see some merit in controlling oversize motors. It's just a bit too late to start now, I think.
If xxxxxxxxxxxbecame reality, I suggest we'd reach a point where a lot of bikes became ineligible at the one time. |
Is your machine authentic or merely eligible? |
