Bucket bits wanted & services needed

Looking for secondhand but good Honda RS125 piston kits with the 15mm pin. Looking for three. If you can help, $$$ please PM me.

Race slugs for a GT380?

Race slugs for a GT380?

No ... one piston is for my de-stroked water cooled 100 which is a soon to be a re bored 54mm for 110cc plus a couple of spare pistons for any possible cock ups while I get it running competitively and future proofing. No sense in building something that's an orphan with no spares readily available on race day.



Extra large KE175 rotary valve fitted to a Suzuki GP100 engine which was originally de stroked to use the good old 52mm KT100 piston for 100cc. Next move is to re bore it, and at 48x54mm it will be a legal water cooled 110cc engine.

The new rule change that makes a 110cc H2O legal pretty much makes persevering with the old 125cc aircooled pointless.

Anyway I need three usable RS125 pistons with the 15mm pin to make this new direction sustainable.

Whilst that is pretty cool, the cackle of a race tuned triple is...more coolerer.

Erm, how do you tune the inlet timing on those disk valve thingies in a fashion that the turbulence from the trailing edge of the crank web doesn't fuck it all up?

I'd ask in the ESE thread, but that has gone off into fairly land where the bikes burn unicorn shit for the perfect flame characteristics.

The crank has a beveled edge so that the wind sweeping in can go up and over it. The inlet port will be higher on the new, larger KE175 disk so the crank will be less of an obstruction.

Yes, sure has. instead of guessing I am just waiting until all is reveled about the Ryger engine, then if its possible we will make a version of one for Bucket racing.

Hey Rob what rod are you going to use now 118mm KTM200?
I are having some issues finding enough deck height for my crankcases and 110 is definitely not long enough for me. I need at least 115mm with my superlow gudgeon piston
Then again if your transfer are not as wide you might be able to get it in where I can't.
Even with the small DIA crank I got off you and the large disk the inlet is not near as straight as I envisaged it would be.

115mm RD400

115mm RD400

Easy to see why those Aprilias have long rods.They bloody have to.
Strike do up to 55mm (in 14mm pin though.)so no good for you I guess.

I can get little end bearings for the RD400 rod (20mm LE eye) that suits a 16 and 15mm pin but I have not found anything suitable for 14 yet. The best (latest) range of pistons seem to have 15mm pins.

Anyway I would love to re use some of those old RS125 pistons that have the 15mm pin.

Yeah I can see some big advantages. esp when it comes to using the 22mm big end and destroking.
Yet I see for a little engine a few grams on lighter weight parts IE 14mm pins 20mm crankpins adding up to more revs less stress.
If you are going te big stuff route Rotax max pistons might be a worth a look I would say they get changed pretty regular as well.

Anyone have a set of wets (wheels and Tyres) they want to sell, or loan me for what I imagine to be a wet race this weekend? Fxr.
