Ok. Some progress. Squish checked again and it's bang on. Clips fitted to piston. Rings gapped- 0.3 spot on- and fitted. Head fitted and torqued down. Inlet studs fitted. Inlet fitted Clutch cover fitted and checked and nothing touches when I turn over the engine. Rear Malossi pads fitted And finally rear hub mounted Now if only they'd sent the bloody studs for the exhaust I could have fitted the first part of the exhaust and done a leak test.

I did a leak test and I have a leak. It's coming from between the cylinder and casing on the fly side. I think it's down to my dremmeling not being perfectly smooth and having to use such a thin gasket. I shall use a little bit of high temp copper gasket paste and see what happens.

what have you used as a gasket during your first test

what have you used as a gasket during your first test I tried the green thickest gasket for the squish check and it was giving me 2.2 so I dropped to the thinnest and it gave me 1.3 so I had to use it. I didn't use any sealant apart from a little bit of grease. I think the combination of the two and the fact that the surface on one quarter of the casing (the bit where I had to remove the half moon on the fly side) is not super flat. I have some high temp copper gasket paste and a I think a thin line of that on both sides of the gasket should sort it.

im convinced that it will all work out in the end

Sorted with a bit of copper gasket paste. Had to fix two leaks from where my inner tube connected to the engine but after that it held pressure. Yay! Loose test fit of the exhaust has revealed that it can't be fitted when the engine is mounted in my engine stand. Balls. I guess I'll just make one out of wood then. Next time I'll be fitting the stator, flywheel and carb. Nearly there!

Exhaust question: Do I use any exhaust paste where it joins to the manifold pipe or will the spring be enough?

I use paste and springs, probably overkill but I know it won't leak. A

Thanks. Seems it's nearly done. Carb, fly and exhaust fitted. Just need to wire it up, oil and fuel it and then kick the bastard. As I said earlier It won't fit in my engine stand so I'm going to fit it in the frame to do that. Hassle if it doesn't work but I don't really have a choice.

Have you tried turning the exhaust 180 degrees just for testing ?

Have you tried turning the exhaust 180 degrees just for testing ? Ah yes, good idea. I can't believe I didn't I think of that. Thanks. I suppose if I just tie some wire between where the spring should go, that'll keep it together for testing at least.

Done!
Started 2nd kick.
Thanks for everyone's help.

Engine back in and running. Unfortunately I was a bit sloppy tightening the gear cables so half way up the lane the cable slipped and bugger slipped out of gear and was a pain in the arse to get it in the right gear. No worry. I got it home and I just have to set the cables up properly and it should be good to go. On that point the clutch was bloody perfect! It's a Crimaz Easy with 3 Surflex corks and the Crimaz conversion to the cover/lever. Can't recommend it highly enough- light and precise! The SIP speedo mk1 doesn't work until I raise the revs so I've got a intelli converter coming that should sort that out. I'm considering uprating the shocks to Pinasco but if anyone has some decent used stuff they want to sell let me know.

Just a quick update. Spent ages on the gear cable adjustment as it seemed to be jumping out of 3rd sometimes. I think it was because the change was new and stiff and I wasn't quite slotting it into 3rd as once engaged it would stay in whatever I did with the throttle and at all revs. The selector was new and an uprated version and I also went +1 oversize on the o-ring on the change shaft so maybe this explains why it's quite stiff to use as everything was shimmed and correct. I hope it'll loosen up with use as I don't want to have to split the engine. New Pinasco shocks fitted front and rear. New Pinasco tubeless split rims on order too!

Twice in the last 40 years I have fitted the gear cable thing inside the headset upside down, that makes holding the gears impossible it goes in the jumps out after 20seconds,,,, scary as hell

Took it out for a run yesterday and it's got a lovely power delivery. Suspension was lovely- just firm enough. Only problem I had was that in 3rd and sometimes 4th it would drop out of gear for a split second then go back in- as if I was dipping the clutch for a split second. I went oversize on the gear changer shaft o-ring (fear of an oil leak) which made it quite stiff to move. Hopefully it'll bed in and with a slight adjustment on the cables things will work out.
Carburation question. Checked the plug and it looked a little lean. With the Polini 24 carb is it out (anticlockwise) on the mixture to make it richer? Thanks

Pinasco tubeless rims arrived on the weekend.
After building 1 rim I found the rear rim lightly touched the clutch cover and it took me 4 hours to work out what was rubbing on what. In the end I had to strip down the wheel back into two pieces and mount just the inner part to find out. It also didn't help that the VMC exhaust stops the wheel going on. It meant that (before I decided to split it) every time I wanted to check I had to demount the rim, then the hub, then the pads, just to get the rim off..... then do it in reverse.
Anyway I found out that it's common with Pinasco rims due to the depth of the outer flange. I also found out it should be cured by a 3 part 1mm spacer kit for the clutch cover.
Thank you Pinasco you bastards.

Thank you Pinasco you bastards. Yes I recently found out the same - nothing ever fits and I am highly dubious about Pinasco products - a lot of bling and a price tag to match but endless problems.

Thank you Pinasco you bastards. Yes I recently found out the same - nothing ever fits and I am highly dubious about Pinasco products - a lot of bling and a price tag to match but endless problems. I fitted Pinasco shock and they went on without a hitch plus they were very well made and do the job as far as ride/handling. Also although the rims are being awkward you have to admit they are beautifully made and the way they work is very simple and very clever. Plus you get tubeless without having to visit a tyre place. On another point- the VMC exhaust - am I missing a simpler way to get the back wheel off with the exhaust in place? I've undone the bolts for the swingarm mounting clip but it made shit difference. I'd undo the joining spring but I can't really get to it plus I'd never get it back on. Any ideas? Change the spring for something else? Alter the spring? Thanks

Update- I was given an idea by the FB forum- remove the spring and use a steel zip tie. Then just cut it to help when removing the wheel. Carry spares for refitting.
