2017 Proposed Bucket Rule Changes.

[husaberg]

[kel]

KTM 85 an easy 24.4hp ... . no effort required,

whats the fuss about, same formula and output as one of those bolt up Derbi racer

[kel]

Sounds more like someone with a back yard full of 85 mx'rs or more likely someone who knows fuck all about the class.

Jason its no longer 1987. The Derbi cup has been in full swing for years, why not throw in the motos to spice things up!

[TZ350]

Spacer plate to adapt a water cooled cylinder to a suitable donor engine.



Crank modification to keep everything within capacity limits.



This is essentially all that is needed to make a reliable and competitive 100cc F4 water cooled two stroke Bucket racer.

Old school, and simple.

Got one have ya Kel???

[F5 Dave]

With a pipe and ign to let it rev, 24 will become?. . .

Yeah agree with Kel. My new AM6 based 90 is looking good for 30hp. Still lots of work with welding cases and reed block mods. But bolt on would be like 24.

I'm not knocking the point you are trying to make; but let's cost this up for someone that can not or doesn't have to tools to do this.

Basic engine = $200-400
Crank mod = $600+
Rodkit = $120
Cylinder = $80-200
Piston kit for old school cylinder $150

About $1000 should cover it, then

Conversion plate (hours of work with the file, drill, hacksaw.
Porting
Pipe
Electronics
Engine mounting in frame.

You might manage to make 18-20hp by luck then spend hundreds of hours chasing the next 10hp, only to have it pop and start again...

Finding some sucker to help you do this is hard work. This option isn't for a person with out the necessary equipment or skills. Fun yes, realistic not really.

Then go and buy an FXR. They can be made to be relatively competitive for not a lot of effort or cash.

TeeZee has already pointed out that with an "un ported" NSR cylinder you can get mid to high 20's with standard cylinder like reliability. I guess his power claims come from recent dyno experience.

[FastFred]

Because it is so easy to make a reliable currently class legal 2T along the lines TeeZee suggests. It would be good to hear why Buckets need this new proposal of Super Buckets.

Maybe the proposers could step forward and make their case.

[F5 Dave]

Rob it's not so easy to make a gryphon engine you propose. My mate just brought that NSR TF and it's a lemon. Example of why people shouldn't be trusted. There's no way he could turn this into a 110 by himself in a million years. Fortunately he still has the FXR to ride.


So it will be up to me to make something race able out of it. Still have to decide if I want to trailblazer or just keep air-cooled like Rick's.

I was violently opposed to mx engines. I have softened my opinion now but I don't think that the proposed changes are right. Either way I am sure that people like me shouldn't be making the decision as I'm not currently racing.

Why not ? You know more about the cost of speed than most.

I note that there's no SI input yet - I don't count Husa...

It's been a very long while since there was a 2 stroke at the front down here. Running on the big tracks exposes amateur tuning like nothing else - and it gets expensive too. I can only conclude that the FXR/CBR status quo will remain as I can't see anyone here spending the necessary...And the FXR's are remarkably tolerant of running wide open for long periods.

[F5 Dave]

It certainly exposed mine.

At least on the 100. But crankpin should Have fixed that.

No I think let those who ride decide.
