What's this such little work stuff? I've done shit loads ( i started building years ago) and be lucky if I've matched the RG so farOriginally Posted by mr bucketracer
And remember the bit I said about wishing Nats Derbi was stuffed full of illegal bits? Well people are calling it an 85 here when it clearly isn't . The Derbi engine well I've only seen the std 50, is 20yeArs more modern than the RG. But its still a learner moped probably good for 10hp as opposed to the 6 the RG did std.
Why Not???: MNZ975.
some might say good looking. but likely as blind as I am..
Dave bringing up the topic.
well every few years now (since 2005) Dave and myself have been at logger heads over this topic (go search the forum).
I think he might have finally realised that these little things aren't going to make huge change to the current front runners (unless riden by someone that can actually ride).
and if that happens; well all good for the class. competition will only make it more fun.
A worked FXR (or maybe something even newer) will shit all over these with an averagely good rider on board.
its not buckets...
you didn't build it yourself....
Well your not going to carry the engine around are you???
You have to put it into something...
we all know that handling and weight makes the major difference.
So lets adjust the rules and ban performance frames/suspension/wheel/slicks... etc.
bugger all of that stuff was around 30years ago...
F##K
so are you saying this years F4 GP was won by a 50???
hope it was overbored above 51cc...

Actually I think std TZR/RGV/MITO engine would be great if you could police it
25 hp ok spread and reliable enough to sell to 16yr olds.
No Honda engines though. Don't want to give people the wrong idea huh

Next thing you will be telling us its actually a Montessa.
I was musing myself about 125 liquid cooled maybe with a 22 carb or something?
But i guess i have a self interest there though?

Yes and it should be attached to their helmet by a rope so the weight swings around like a pendulum....
Why Not???: MNZ975.
Yea na...
Though I have one already.
Husa maybe you just need to sort your little girl out. Buying a Yamaha would be a good start.
Maybe to answer your older statement/question. Rather than welding up your crank, why not just find a larger rod with a larger big end shaft then just grind in the required offset. Maybe a Yamaha rd400 or something of that elk.

Nah i am stuck with the 20m pin cause i am stuck with it, cause it suits my long rod (don't get the wrong idea)Yea na...

Looks like it has to be sleeved which i think the aprilia was anyway, their crank actually looks like it has brass rings in it?
Anyone else ever noticed that?
Maybe they too used a NSR crankshaft???????????????

No no. I mean (now that I'm not typing on a phone) the Derbi GPR or Senda is a road legal bike built as a 50, not sure who made the engine for them. they later changed to the Minarelli AM6 like everyone else.
The F5 bike is like this. The F4 has an aftermarket 'road' based (whatever that means) 80 kit on it & perhaps some extra stroke on Daves bike compared to Nats. If the premise is that aftermarket but road based is legal then it is legal. I'd tend to think it is more a performance part so I'm uncomfortable with it. But it isn't a competition part so it is within the rules.
These are sold to kids to bolt them onto their 50 & ride around pouring low octane gas & forecourt 2-stroke & survive. They aren't a race part.
There are of course companies that also make race barrels for them.
Don't you look at my accountant.
He's the only one I've got.

I cant be buggered reading this whole thread, but my take on the whole bucket rules scenario is this.
If the 100cc watercooled rule is kept in place as the only basic stipulation, then the whole 2T thing becomes much more viable to way more people.
You then have a HUGE choice of cheap engines to choose from, and aftermarket or road or race parts it all makes no odds as starting with an 85
you will have to bore and or stroke it - or if its a 125 you will at the very least have to sleeve it.
All the other parts such as ignitions,carbs, pipes, rods etc are all freely and cheaply available - but even with the most expensive choice of base engine,say a 125GP rotary valve Aprilia RSA
you will still have to sleeve it down.
Thus the performance will ultimately come back to how competently the tuning was done - and the RSA done by a guy with a huge chequebook and bugger all knowledge will still be slower
than say an engine based on a MX85 bored out with Ignitech and a trick pipe and real good porting.
And in the end the RSA may never be the best choice as everything is huge to enable 50Hp at 14000 and "fixing" all of the issues just simply may not reap the best result.
And NO I am not saying this as I want or need more work, I dont - so forget about ringing me to have one done.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.

OMG you cant not do that what about the spread what about the curve may be its the top end power

What do you mean by 'performance potential limited to 30HP'? Is someone going to supply a mobile dyno at the tracks to verify this?
There is already a shit load of 'hot motors running around'.
Not having a go at you personally but over the years I have seen a lot of 'proper race bike' guys show up to buckets with the idea that it is a bit of a joke and they are going to clean up. Bayden Sprozens comes to mind. Maybe the rules don't quite suit as to be at the pointy end you have to put in some hard yards first ie develop a good machine and if a motor that developed good hp out of the box ie MX85 (and weighed buggar all compared to current legal offerings and no one has said much about that point) could be made legal for the class then that is a fast track to being competitive and too bad for the developers that have already put in those hard yards.

You still have to put the engine in a frame, set the bike up, make the exhaust fit, tune it, blah blah blah in order to compete. Whilst I agree it might slightly help those looking for an easy way in, to speak as if this will now allow a competitive, easy to set up bike on the grid for any joe to start dominating instantly is exaggeration. Only those willing to put in the hard effort would see any reward from this. Shit most won't even finish the engine swap!
I still maintain that if this rule was passed, the percentage take up would be minimal in the grand scheme of things. Most people just want an easy, reliable, fairly competitive FXR to have some fun on.
