Supermono 1300cc racer project.

Hi

Hope you're on the mend and the project is going well.

Have you, at any time through the various incarnations of the design, considered a stepped piston as a possible way of getting around the oiling up? It still keeps the purity of a single cylinder and at the low rpm of your big version probably would be ok? Just a thought.

Hope you don't mind me asking.


Cheers

Hi, yes ive seen the stepped piston idea. I dont really need it , as ive already got permission to race the 1300 in an 800cc class. it would be good to use the stepped idea in , say, a 250 class, and use the step to have 350cc under the piston to get extra boost pressure.

Hi

I was thinking more of using the annular space "between" the piston diametres, a la the Norton wulf. As a way of compressing the  air without it passing via the space under the piston where the oil is.

Dunno. Just a thought. 

I guess that if the oil doesn't spoil combustion then it's probably not worth it anyway?

Hi

no probs with the 2 stroke oil, indeed, i need it to lubricate the rotary valve.
but it is less than ideal when used with laughing gas
and probably very detrimental with NitroMethanol

slight progress with spacers each side of head, and AN adapters. I am mended anyway, and off the Warfarin.

Looks amazing

Looking forward to seeing the end result. Glad to hear you're mended.

This is gonna be one unusual machine to ride. I'll bet it's pretty quiet mechanically. There's nowt in there to make the "usual" noises. Apart from a girt big piston.

Great to hear you're on the mend, and can't wait to see the finished bike

Nice little beastie!!!!!!

i got a few more bits ready, just some oil holes, nitriding, and some coating on the rotary valve left to do.





and the clutch wont be sitting on the crank- ive opted for a harley primo belt drive, with a gearbox to be baked into the swingarm. a bit more work, but it will be the business.

great stuff, good luck with the remainder.... on the home strait now

Brilliant! This mega project is back!

Very nice

just to digress from motorbikes a while, my rocket sled is ready. the race is in 2 weeks time, on the ice.

With a mosheen as cool ass looking as the "rocket sled" 🚀🚀 you may digress away from bikes as much as you like as far as I'm concerned ....cheers, Michael
