Rules re engine mods?

[bucketracer]

BUt you could essentially take a top end off a road bike, and engineer it to be exactly the same as said aftermarket top end, and it would all be legal?

If you could do that you would be a living legend..........

For engine/bike builders, and there are some handy ones, that's pretty much what bucketing is about..................

KE bottom end, RG400 barrel is legal. Can't remember the head....

[RMS eng]

The best way to stay legal and be competitive is to get yourself a Suzuki GP, everything else is pretty much a wast of time ..........

has a GP125 won any races in A grade at Mt wellington,or a GP race over the years?.best thing for a GP125 is a RG400 cylinder.

The ESE engines are plenty fast enough but to win in A grade takes a top A grade rider, Dave M came close to wining a race or two with some very brave rides on a borrowed ESE bike but the std GP's handling let him down.

just go out and get a STD bike to race... pull EVERYTHING off until it stops...put that last bit back.. race it for a couple of meets, THEN start modding it.... starting with tires... then work up from there...

Like I said... so simple I'm surprised everyone's not doing it.

Don't start them, there will be a rush on parts with skyrocketing prices followed some months later by some trademe firesales & a slump in price when they realise that they don't bolt together. Either that or RMS will set up a production line & get rich pumping out replicas.

Rich off bucket racers, yeah right. . .

I think this seems to be the go with some of the current breed of bucket racers, (myself included), Just my order is outta whack, got tyres , but haven't pulled everything off as yet. but getting there. If anyone has more money than cents(Max before he changed class) it would be interesting to see how the new yamaha R1 25r competed against the rest. Meant to be pretty good outta the box just prohibitly expensive at this stage. But watching the dva I am!!

Hmmmm... I have a spare RGV150 Bottom end sitting at home - could i Bolt anything up to this? - actually, thinking about it i have a RGV cylinder too (dont know what condition it is in after my piston exploded in it lol)

RG400 top end on a KE125 bottom end.
Bolted together in about 10 minutes after a bit of fileing and some bogg...

[F5 Dave]

You mean an RG150 bottom end? Yes that would fit an RGV250 cylinder. But of course be excluded as watercooled 125 as a cursory examination of the rules will point out. (unless you sleeve it down or do some hoady air cooled conversion).

If you mean RGV150 then it won't fit , wouldn't have an inlet for a carburetor & of course would still be illegally large.

Or do a sleeve on an RGV150 aircooled down to 125. I've done that & there was another.

It is an RGV150... so the aircooled version. So there is nothin I could bolt on to it (a 125)??? Either that or is it easy enough to sleeve them down to 125?
