Definitely interested in a 65 crank assembly please - if you’re prepared to ship to UK ?

Nice

So pressure feed is maybe the only common factor (presumably split with a tee piece; one pressure tap to two tanks).

What price tor 67HR P/S please Patrick ?

Easily dome. Especially when they went from Evo to RS; then followed that with RS Evo. I always used to think of and call that type of CMB crank arrangement, Evo type, but had to revise that when they went to RS Evo.

As far as I know, that’s a gold head .67 Evo; from the same era as the .45 and .90 gold head Evo. Those came before the purple head Evos. After the purple head Evo, came the .45RS and .91RS (red headed). I don’t think the .67 ever made it to RS. They stopped making double bobbin crank .67s...

Ok. Thanks

Hi Derek, Do you still have Picco 45 pistons and sleeves (old type and / or EXR) ?

Thanks Anders.

This is a superb thread, and a superb initiative. I take my hat off to you Ricky, for what you’re doing here, and the effort - not to mention resources which you’re putting in. Cant wait to see the end result. Some superb info and knowledge sharing - by everyone in the thread too.

I’m loving what you’re doing here Terry. Awesome stuff.

Wow. Huge respect for taking this on Ricky. I very much like what I see so far.

Thanks Joe

Thanks very much Joe. Sorry to cast doubt, but could there be a typo in the Picco rod measurement, or could that length be for a Picco 45 EXR rod ?

Thanks very much Ricky. Much appreciated. Looks like the Picco 60 rod you have, has the same dimensions as the “believed Picco 67 EXR rod” I have. I think some of the early Picco 60/65/67 rods (the ones with cast rotor discs), may be a good fit all round, but obviously very much out of...

Going back to head shins, I’ve had success with a compass cutter and copper foil. It’s a bit painstaking, but managed to make quite a number of head shins that way.

Hi All, Long story. I’m trying to fix an MDS .61 engine, for a friend (actually more than one). These engines seem to have borrowed quite a lot (in design terms), from Italian engines of the time. Porting layout is like Mk1 Picco (four transfer / boost ports), with a drum induction setup like...

I think you’re right. It has 65 stamped on the mounting lug.

Hi Ricky, Great info, and great sharing of info. It’s good seeing you on here, and some representation of this area of the hobby. I’ve popped along with my son, to a couple of the Victoria Park events - attending under Norman’s wing. I think I may have seen you at the last one of last year; with...

Yeah. The HR has the same bore / stroke ratio as the RS, and the old style .45 Evo engines. The V5 and VAC 45, are longer stroke engines, and I think, have a slightly wider and higher crankcase. This also affects the position of the crankpin, and the hole / slot in the periphery of the drum. HR...
