Hi all,
Since my last post the bike has come together pretty well. Biggest pain was sorting the primary side/clutch to get alignment right. Needed quite a few spacers, then the SRM cush nut was catching the outer cover (which I stupidly initially thought was the three long bolts into the crank case hitting the crank - penny finally dropped when I shortened the bolts which made no difference). So I fixed this by carefully grinding the outer case where I could see it had rubbed. The outer case was a bit of a mess anyway as it had a big hole in it where the clutch had made an appearance at some point, so had that welded up. Both inner an outer were quite warped, but I'm pleased to say that touch wood (and much to my amazement) it has not leaked a drop of oil!
So bike is now up and running and covered about 200 miles, mostly in the playground that is north west Scotland (very gentle, although starting to open her up just a little towards the end. Oil changed after 50 miles). All seems fairly sweet and she is very willing. Very bouncy on the front on first outing but new tt100 front tyre seems to have cured that. Brakes better than expected, particularly the front, although it is not perfectly 100% smooth (standard 8 inch 1/2 width which I left with shoes that came with it - green lining - used for racing I was told).
She is a heavy wet sumper so I read the recent post on that with interest - I will pull the timing cover off and check the pump is seated fine but otherwise I'll just live with it as I have a sump with a plug. There's obviously good return to the tank and after that many miles without problem I'm willing to assume a decent amount of oil is getting to the right places.
She has also stopped charging (or never did - cant be 100% on that, although gut instinct is that she was charging initially). I'm on 6 v, dynamo serviced by Priory, new good quality regulator. I refitted the drive chain that came with it so I'm suspecting that has failed which is going to be my first check when I look at the oil pump. Probably go for a belt conversion.
There are also oil leaks - not figured out quite where from yet - its definitely engine oil and drips from various places - sump, frame and quite a bit around the center stand / gearbox - could well be some dodgy fiber washers on the tank I wonder?
My only other general comment is that she does have quite a bad vibration (although I've definitely felt worse), starting at about 55 mph in top which I think started to reduce a little beyond about 65 - not been much past that so cant say yet what higher speeds are like - I guess this is not uncommon when there has been no attempts at crank balancing. Felt it more through the seat than the bars so refurbing the seat may help! Also might get a bigger gearbox sprocket to increase the cruise speed in the sweet spot.
I'll fit an oil filter at some point - like the look of the canister which takes an Enfield filter, and there are of course a few other finishing off bits and pieces for next winter!
Thoughts on any of the above very welcome!
