Not really the place to be going on about this but, bit of a problem with the starts on these 4 hour's, I like to arrive early to get the plum spot for the start and I'm usually within the first two or three on the line. As the start time gets close and there are three or four rows deep of bikes some smartarse will always push in at the last minute where there is already limited room. This start I had some fat bastard push in next to me so as the gun went off (I knew I would get a better start) my handlebars hit both bikes either side (I had pulled my bike slightly back, so i got them both in the back), in the mayhem I nearly got knocked off (others did). BUT somewhere someone hit my front brake leaver assembly and loosened the banjo fitting (broke the small tang off that is supposed to stop this happening) so you can imagine my surprise/dismay after a long down hill section suddenly when I need it the leaver goes back to the handlebars not very funny. Hit the gate at the bottom and got latched into it. Took a while unlock myself from the bloody gate then a slowish first lap with heavy rear brake usage. Next year I'm putting an electric fence up round my bike so no pushing in! Might use my 60,000 V cdi to power it too Bastards. Nevermind it was a good day anyway subsequent laps were much more fun after brake surgery, that's my story anyway.

Enough bullshit, back to cylinder/engine making.

I had wondered why you described it as the "acerbic 4 hour"...

That shit should be covered at riders briefing. Sounds nearly as bad as the old Greymouth setup where no grid positions were allocated and it was first one round on the warmup lap...More fell off on the warmup lap than the races proper.

Who thought that one up

Totally love it ....... .... "Fuck Them".

Well Husa's dad let it happen....wait for the screams, LOL....

It wasn't until the late Ray Shearman and I started doing the first few rows on the day for the club that it got better.
AFAIK they're still only doing the first 2 or 3 rows of each class.

Hehe there was a few times i did sneak myself to the front row in formula races as well.helps to know the starters.
Remember GMR is a classic fun race shakedown meeting, we are not racing for sheep stations....tm Ray Sherman every riders briefing he ever gave.
Pretty sure other than the first races of the day that were always a lottery, the marshalling was meant to be how they finished the last race.

Glen, the box has been opened
Everything seems in order
Be keen to see how they cast, I'll show the setup and cast on here?

[Grumph]

Is that warped Core box usable - if that's what it is....

[Flettner]

The one that looked like a bird box ,yes all the boxes are warped a bit. But a bit of pressure will close the gaps up, the big vice. It will work ok.

[Flettner]

Power valve for the 360 engine, blade type.

[Flettner]

The idea is to cut a gear rack straight into the valve blade with support rollers on the back side. A shaft with a gear made into it and there you have it, turn the shaft, simple powervalve action. Hooked up to an R1 servo I guess as it works well on the Kawasaki. Also I will put in an ultimate back up stop (on the valve itself) so the valve can never fall into the piston, if the gear mechanism ever shit's itself.

Flettner, is there any possibility of doing such a P-V set up as a potential 'bolt on' - to convert earlier non P-V cylinders?

Anything is possible, but it would be difficult. You would be better off to make new cylinders with valve capability already cast in. Water sealing would be an issue. Casting new cylinders would also give you the ability to upgrade the ports to today's spec. It's not that difficult to cast cylinders, as seen earlier in this thread just some time and patience. (and some plastic beads)

Cheers Flettner, & you are of course correct..

- I was idly thinking of the way its done - machining old air-cooled barrels to slot in big reed valve inlet boxes..

I assume you are thinking of replacement Kawasaki triple cylinders? Cast new ones and you could have it all, big reeds, power valve, eye ports and well shaped transfers. And nikasil bores. The trick would be make them still 'similar' to the old ones to look at.
