Pingel high flow dual outlet fuel tap to fit my RS125 tank, standard one wouldn't flow enough to feed this motor

What's left to come until you can start final assembly?

What will you be doing about wiring? Can you buy premade looms or will you have to do it from scratch?

Ultrasonic bath thingy?

They're brand new monoblock barrels, 68mm big bore cast specifically for my 7mm over stroke crank. That's why they've taken so bloody long to arrive!

Not worried too much about that yet, I thought you'd be able to buy looms, for instance like what people use when they convert an mx bike for road use??

Either that or make one/butcher one off another bike. It'll run with minimal wiring but I want it to have lights eventually - might run it on a daytime MOT for a bit in the meantime.

It's off for pipes building at the end of this month, some more bits to come then I can start building the motor.

Happy Days!!!!!!

Now just go through the castings andremove any flashings or irregularities, maybe knife edge the inlet dividers and radius the transfer ports and you're set!!
I expect it completed by the morning

Warning, high in carbs

Looking good mate. Custom loom wouldn't be that much if you're not running many leccy bits, and worth getting one done properly.

Be unbelievably frustrating to do all this then be buggered about chasing an iffy connector!

[Yazza54]

Aye will have a digital dash and probably worth fitting lights, not much to it though. I'm sure I could use one off another bike but maybe it wouldn't cost much to have one made as you say.

Cannot wait to see it with spannies on. Gonna look awesome.

Who's making the exhaust for you? Have you got any drawings or a design?

If you have I can run it past my man in the know at work and get his opinion if you like? And he really, really is in the know on two stroke exhausts (confuses the feck out of me )

[Yazza54]

A bloke called Ken Gubbins his company is called TSA two stroke addicts, he's done a lot of these and is quite highly regarded by RD owners. In fact people tend to favour his pipes over the likes of gibson, jim lomas etc. but he's a one man band so probably never going to be as big as those guys.

Great thing is he's itching to get stuck in which is a big deal for me and is happy to measure everything up from scratch and design them for the spec I have rather than trying to sell me something that would work "ok" which I had from some people.

So design wise that's his bag, this isn't something I'm prepared to get too involved with, there's certain things I'll mention like stinger length, diameter etc that I've read up on and seen people test, but it's mainly down to him!

That's cool mate, and sounds like exactly the right thing to be doing. It's such an unbelievably complicated subject, and such small differences seem to make massive changes.

This chap's a good mate and he's absolutely passionate about two-strokes and designed quite a few of the 500GP systems for the big factories back in the day. What he doesn't know about two-stroke exhausts isn't known

[Yazza54]

Sounds like a good person to know

Think of a slightly younger Fred Dibnah sitting in his filthy overalls with his glasses on his head amongst a room full of sharp suited graduate engineers

Drop us a line if you have any questions mate and I'll forward them on

[podman]

Really looking like a motorcycle now Ryan, you must be at the "inspired" stage at the mo!

[Yazza54]

Definitely mate, needed to make the effort tonight to spur me on a bit

Threw the seat and tank on again





Pingel high flow tap fits nicely with enough room to get me grubby fingers in

[Yazza54]

Chains on and all lined up so all my guesswork careful measuring paid off





Ignore the tatty subframe, still needs a fair bit of modding.

Pleased with how neat the sprocket and carrier turned out, it's not that obvious but it's had a hell of a lot of work to fit the mito swingarm.



That's it for now, ready to have its pipes made. Anything that could potentially be in the way is fitted so it can be designed around. Taking it to Kenny @TSA this Sunday.

[Yazza54]

Still not decided what cans to go for, normally fancy carbon but I've read they can fall apart from the vibes of a big 2 stroke and Kennys ally cans are lovely...


What yous reckon?







The pipes themselves will be in stainless like these

[Jazoli]

I don't like the big TSA badges/stickers on the stingers, they'd look better without them IMO.

[Yazza54]

Just stickers mate but the cans look very nicely made... Some look naff but the way they've been machined etc might look better than carbon, and last longer.
