A crashed Bucket

[TZ350]

Now that wasn't well thought out at all, they'll have to use 24mm carbs - "24.2 ... F4 2 stroke engines over 104cc are restricted to carburation equivalent to a single 24mm carburettor"

........ good spotting Kel, now the lazy ^%$&%*& ers will have to read 1040 pages of the ESE thread to find out what needs to be done to 24mm carbs before they can get any power out of their 100's.

I bet they will be tempted to cheat, or maybe its time to drop that silly carb rule.

[Pumba]

someone else will need to do it this year as I don't have a MNZ licence.

Not true Kel . All MNZ ask for is feedback, and provide an email address to submit to. I cant find anything to say you have to be a MNZ member to provide feedbaack.

wonder why I thought you had to include MNZ number with submission . Never mind, I'm quite happy for them to have 107cc and be restricted to 24mm carbs
But that crash rule, I don't think it works for buckets. If the bike is checked and cleared surely the rider should be allowed to continue? We might end up with races that have no finishers

The original draft several years back captured that carb rule. It would benefit quite a few engines from several manufacturers for several over sizes. But whatever.

[bucketracer]

... the 107cc rule change will have much more appeal to many people, and may finally see 125's on the scrapheap

Maybe a list of engines that would benefit and the maximum KT100 piston OS that the shorter stroke MB100 could use compared to the others and I think we would see it was more of a benefit to the few than the many.

Many over-sizes!!!! well not on the Suzuki GP/TF/TS or any of the other motors with a 50mm stroke, with these motors your over the 107cc limit with a 0.25mm OS KT100 piston.

0.25mm is still 5 KT100 piston oversize steps. I find it difficult to believe that anyone thinks 2cc is going to make a performance difference. It's 5% so maybe 1hp. To affect say Kel, the original 105cc engine would need say 25hp. Assuming watercooling of the 107cc engine versus Kel's aircooled engine. Not picking on Kel, just an example. Feel free to list all the 100cc 2T engines making 25+hp racing at the moment.

I didn't make the proposal by the way. I'm quite surprised it came back. Also the last box of KT pistons I got cost $6 ea. Be great being able to use them with a stock stroke crank rather than having to build a $1000 crank to keep legal.

Well I'm claiming credit for crushing the 100 overbore nonsense last year, someone else will need to do it this year as I don't have a MNZ licence. Should be the same argument as last time, the rule should apply to, or benefit all. It can't be to the exclusive benefit of one (or two) bike owners who can't be bothered de-stroking.

We all love the "s" as it sends Husaberg in to a tailspin

husaberg has a small h
That post does you no credit Kel.
Very few pistons suit the 100cc bikes, its well documented. Feel free to make it about me though.
According to Frits Wob and most anyone who can actually read and interrupt a rulebook the 'S is a clincher.
Yawn

[F5 Dave]

Oh no, that's just not true. Why there's the 1978 bushwhacker 4th oversize, and then there's . . . well there's loads.

Touchy he is mmm. Dude the lol was placed at the end of the sentence to indicate a light hearted piss take.

100cc 2T engines making 25+hp racing at the moment.

Jasons RG400 cylinder on a KE125 bottom end was good for 25, in fact a RG400 cylinder is probably the easiest way for a reliable 25+hp. They could use the KT100 pistons too but only up to 0.25mm OS if 107cc came in.

I find it difficult to believe that anyone thinks 2cc is going to make a performance difference. It's 5% so maybe 1hp.

I would very much like another 5% on top of the current overbore limit for air cooled 125's and to be fair plus another 5% should be available to all the others too.

Be great being able to use them with a stock stroke crank rather than having to build a $1000 crank to keep legal.

Give me a suitable rod kit with a 22mm bigend (RGV250, RD250/350, RZ350 the list goes on) and $260 and I will get you'er old crank de stroked for you so you can use KT100 pistons and be within the current 100cc rules.

[jasonu]

..., or maybe its time to drop that silly carb rule.

It is not a silly rule. You have shown you can get 30+hp with that restriction in place.

So the point of the rule is??? ....

It was a pretty good summary of your self serving attitude.

Not sure Kels argument for one rule for all is self serving, but an exclusive few wanting an extra 5% for their own benefit looks self serving to me, sure it may be easier and cheaper but may be you could explain why that is not self serving.

The ethanol fuel which would obviously benefit some subclasses more than others.(his augment that it would not)
The 107cc saying it was all about a couple of people but mainly me when it was obviously not,
The repeated suggestions that there were plenty of other suitable pistons for the 100cc bikes when there clearly was not.
Kels augment was not about one rule maybe reread his original post.
If you read any of the stuff I have said all along I have always said I don't care if the others get a few extra cc as a compensation.
but, I don't think it is appropriate to argue that the actual reasoning for it with 4T's is because of availability as they have other pistons that are commonly available and cheap.
Also the the same argument for OS pistons is not the case for the 56mm bores for availability as they have other many pistons that are commonly available and cheap.

The 2t guys need to sort this out between themselves as the 4T guys must have a great laugh about this repeated shit fights over a few cc's when they have lobbied and got about 30cc over a few years the 2t guys got nothing
