ESE's works engine tuner

It would still be better than a GP125 frame.
Is somebody or a group of somebodys pushing this change, I personally dont think its needed, but wouldnt be bothered if it happened. It would maybe cause the FXR brigade to be stronger with more FXR single model competitions to start up. What are the merits of 125 watercooled when a 100 will do the business ? Maybe start a new thread on this as it has nothing to do with TZ's development stuff

You are right, almost anything is better than a GP125 frame. No offense to the GP125 folks, the plain truth is that particular frame was never intended to cope with that much hp and the on track forces (cornering, brakeing) that type of hp will deliver.

The merits of a 125 vs 100 with the same rules is odvious, 25% more cc = more power. If it happens I will be looking for some RG500 barrels. I agree with you, it is not needed or wanted (by me anyway)
I think these points are valid in this thread as the machine being developed, described will most likely be uncompetitive if these rules are let in.

Right, I am off to watch the Indianapolis super cross. It is live on TV right now.

I like the rules the way they are and I am enjoying finding new ways to live with the 24mm carb rule. It would be a pity to see the FXR's go their own way, I don't think old style buckets would last long on their own.

The GP frame is not great and bracing it hasn't helped us any. Two of the team have opted for RS chasis but Chambers and myself kinda want to do it the old school way.

We have examined every part of the frame and fork internals, fitted emulators and experimented with different spring rates and shocks, but don't know what the answer is yet.

When we are on top of the engine we will have a serious look at what we can do chasis wise and if we need to go to a doner bike....F5 Daves posts on forks and handling make very interesting reading.

I wanted to be the the 2000st reply, but Buckets4me beat me to it.

Buckets4me have you had a look under Dads bench lately? a bunch of GT125 engines have appeared there, and there is also a large offcut of 2mm copper sheet in the corner. What does all this mean????

I heard the new rules would allow 200cc aircooleds like IT & KDXs or 125MX engines up to '95 taken out to 144 like in AMA rules.

[jasonu]

I heard the new rules would exclude dickheads. Looks like you're out Dave.

[F5 Dave]

Is that why you left the country?

We'll have to form a club of our own.
CR250s in minimoto frames.

I know a guy who squeezed a 250 fourstroke in a pitbike, I believe it has caused a fair bit of pain.

I'm interested to know where this is coming from; who has proposed / suggested there should be a change... why follow the AMA when the B.R.A NSW framework would suit our environment far better, especially with the slow gradual demise of 2stroke junior MX classes (85cc). http://www.ozbucketracing.com/

I would have thought that the last thing we need is another ~125 class.. 38-40Hp buckets on gokart tracks

Though it would be fun.

Why even look at following either of those when there's nothing wrong with our current rules, if It aint broken dont fix it!

The rules are pretty well spot on. TZ has proved it is possible for a 125 with a 24mm carb to make competitive power. The unlimited 100s should supposedly clean up but don't and those other bikes seem to go OK. As always it comes down to development and who is riding it.

second that
(but I have an old rm125 engine under the bench just in case)
