CRM80 build?

[richban]

Surely not a professional tuner

Nah he's a cowboy. Last time I had to even put some of the engine together myself. Spark plug I think its called.

Just jealous really. I want 30hp. Or more coz more is better.

Get your self a FZR250 and cut it in half.

I have 2 here. is that four engines.

Maybe I already have one. Or maybe something else. What ever the next engine is. Its going in my RS250 roller. F3 is to expensive buckets are where its at.

This is a bit of an elephant in the room, so simply because it doesnt say "race" or "competition" on the vendors website they are legal for buckets. On another page we arguing that big end bearings are race or competion. While the rules dont explicitly say what is or isnt competition or race parts, buckets have usually been made from street bike or farmbike origons. I dont know shit from clay when it comes to the differences between a crm80 and a nsr80 other than one sounds like a motocrosss bike and the other a road bike, are they identical porting from stock , gear ratios the same. its kinda the same as the TM/TF /TS /RM thing they all look the same but some are more legal for buckets than others. Is the bucket community just ok with this CRM80 thing because its some flash Harry superbike guy going to come over to buckets and give us the learn, or maybe because they hoping he not really that serious anyway and after this thread has got to 20 pages will never be seen in the cheap seats again.

they also made a CRM 50 same motor ,also called a MT50.same bottom end as the 80,i have a book with all there specs,same gear box as MB50,NS50,.RM125 and TS125 from 1976 on are no were near the same.only CRM that had a MX motor was the 250

If a CRM80 is just a trail bike, does that make a Yamaha DT125 legal? it had a head light too and sometimes you see the engines on Trademe and I like the look of them, there was a list some where that I think Skunk put together, but I cant find it.

[Moooools]

I am getting Wob to do mine as Mick never had to tune his one either
I am not the only one either we are taking over the show.

There could be up to 25 2 stroke (Yes 25) 30HP at the rear wheel Buckets at the Battle of the Buckets next year.

I am of course also supporting the small NZ tuning industry too.
I therefor feel I should at least get a MBE or a OBE.

Racing is racing. It isn't a DIY tuner/riders cup is it.

You should really stop banging your head against the wall. You have probably done it enough judging by the fact you are building a two stroke.

DT125 is legal as assuming you mean the AC one either that or sleeve the LC one to 100cc
with a 24mm carb

Oh and the CRM250 water cooled thing was a road legal trailbike, good adventure hack, decent commuter, you'd have to be mad to race one in any sort of off road competion. I used to use mine for marking out trails and commuting, great for that but no way fast and the suspension was as soft as a soft thing.

You are right the four stroke are such a superior engine that the rule makers have to keep changing the rules to suit the 2 stroke.Thats why they give them unrestricted carbs and a displacement advantage to compensate for there obvious inadequacies.


Cows follow the herd too Much like sheep follow the flock. Mooo.



PS At my place when a cow gets a bit slow or it challenges my authority.
I turn them into mincemeat

That's how it is aye Moooos

Do you know what has a better power to weight ratio than a two stroke and is more reliable with far less "inadequacies"?
A gas turbine.

Feck it I can't even be stuffed having this argument. Let me know when that bike of yours is on the track and we can settle this.

A yes Moos Thanks for giving me more Fodder for bad puns.



I agree when the Flag drops the bullshit stops.


The gas turbine has been done and is not as far as I am aware a Four stroke.
Here is A Suzuki SP370 jet engine assisted bike.

[White trash]

Fuck you girls are funny.

While you're all arguing over Choppa's CRM80 and shit, he's off riding his BMW Superbike at Taupo. Dropkicks...........

See ya on the track soon ladies.

[Moooools]

The best bit is that moooools has nothing to do with cows. Just happens to contain mooooo. A sound that cows make. Did you know that? Really quite amusing.
While there is nothing really funny about your screen name. I did find this compilation of husabergs crashing; which made me a little bit happy inside.

And while I am perfectly aware that a gas turbine is not a four stroke, the point was that comparing for strokes to two strokes is like apples to oranges. The only true was would (but still a pointless number) would be to measure efficiency- i.e. power vs rate of fuel usage.
Tell me who wins that one.

Anyways mister funny pun man, time to let this thread resume to talk about Choppa building a bike.

[wildman]

Hi guys i have a question, is an Aprillia rotax 125 engine legal for bucket racing if i sleeve and destroke it to100cc. And if yes does the fact that the only vehicle it was in here in New Zealand was a Superkart make it a kart engine?

She started it

You are right though White Trash. He's off riding and yet hes still way further ahead in his build than you are.

He after all has an engine.

Ps your Tag line tearing Choppa's A'Hole very funny
bugger that.
