Supermono 1300cc racer project.

I only dream of doing (as in building) stuff like that. Well done that man and for sharing the info

Good luck with it

Mmmmmm!!

Coming together!!  Much left to do John?  How far are you from "Bangs"??

6 months and one thousand pounds away- forged con rod, liner, new piston and a few needle rollers and seals.. a proper clutch will put me back at least 500 quid too, but not necessary for a start up.

Any reason you chose to use the cross valve rather than the aspin which is easier to seal

The Cross valve is more of a challenge- i like that, plus its a more compact.

What MotoGP should be all about!  Good to see the progress and shaming my  continued lack of progress!

All the best and thanks for sharing the beastie with us.

Regards, Bill.

I cant wait to see a video of this beast running, I bow to your engineering skill

[guest1306]

Thanx Jools, but im really not that clever at the engineering. This is a very basic engine, all the parts are admittedly handmade by me, but the tolerances are not that tight.

[guest1380]

Wow it's really coming on! Don't short change yourself regarding the engineering skills. Being able to make the components involved and having the knowledge to make it all work would put many to shame.

I've got to ask though, does at also come in black as Judge Dredd's new hack? 

[guest1306]

Thanks Boatloader. Black would be naturally best, but the silver paint is a few bob cheaper. Ive now ordered  forged special one off piston and same forged rod, so thats gonna set me back an arm or leg.
As soon as i get those then i have to decide on a harley drag bike clutch or go for hydraulic drive- the latter would be nice, just set the engine to max power revs, and use a throttle to regulate the hydraulic drive.

[guest1380]

Oooh hydraulic drive would be good max power or torque everywhere! Could you 2wd it?

[guest1306]

Small update on whats been/not been happening lately, although ive been working away from home a lot. -

The piston and rod, specially made by CP Carillo Pistons are soon ready to pay for, so i am selling off some stuff to sponsor this.
Slicks tyres are now on the bike.
Had a good tip from a French guy not to use a big heavy chain as the centrifugal effect can break it when it rounds the sprocket, so i plan on putting a double small chain on.
Havent bought a clutch yet, may even make one.
Have sawn the slits in rotary head where aluminium bronze inserts shall hold the sealing rings. the watercooling is not done yet though.
The hydraulic drive idea cant be done as it would require a big cooling system, and there isnt room for such.

[guest1306]

have gotten two of the allybronze inserts in the half round ones). Busy milling out the flat straight ones now from a round bar- a ordious task, shame i couldnt scrounge the correct size flat profile





and a new rotary valve with adapter for holding the cam belt cog

[johnr]

stunning! im gobsmacked with awe!!!
