Re: SQ 4 MkII first start - oil and smoke....

I did oil the top end quite generously before first start and there is still some residual oil around the valve seats but not enough I think to be able to run down the inside of the guides. Watching it run with the covers off, all of the oil seems to drip from the end of the rocker spindles and I th...

Re: SQ 4 MkII first start - oil and smoke....

Well, I still don't know what the 'right' amount of oil left in the sump should be but can't find any problems with the circulation.
Wondering now if it's just a question of getting a few miles on the clock to bed in the rings and hope that the smoking then decreases and disappears.

Re: SQ 4 MkII first start - oil and smoke....

Another update. Removed the sump plate and gauze, pickup pipe all looks good and positioned nice and low. I attached a hose and blew through - no passage of air at all so no leaks in the pickup side it seems. Phoned Morgo and they suggested checking that there were no restrictions in the the return ...

Re: SQ 4 MkII first start - oil and smoke....

Thanks all, I've drilled out the solder blockages from the top oil line, reassembled and that feed is now working fine. Also, the return flow is strong into the tank so I 'm wondering if perhaps the scavenge pipe pickup is too high in the sump. I'll try the tests on the scavenge side tomorrow and al...

Re: SQ 4 MkII first start - oil and smoke....

Quick update - the lack of oil to the top end was due to the fact that the top 'T' pipe section recently bought from Drags was completely blocked with solder.

Guess I should have checked it before fitting....

SQ 4 MkII first start - oil and smoke....

The good news is that the bike started up almost immediately after 40 odd years in bits with no nasty noises! The new Morgo pump seems to be working fine as I have a healthy return flow to the tank. However, after a few mins of idling with little or no smoke, a blip on the throttle produces copious ...

Re: Sq 4 distributor setup

Many thanks Simon! I'll give that a go tomorrow. Although I'm still waiting for a number of parts from Drags to complete I think I'm now close to the point where I could get the bike setup ready for its first kick over in about 40 years and hoping that the result will be a sweet sound and not a horr...

Sq 4 distributor setup

I've become separated from my manual and am trying to assemble and time the distributor on the Mk2 and make up the HT leads correctly. I think that the firing order - from placing finger over plug 'ole - is RH front, RH rear, LH rear, LH front but would appreciate confirmation. What is the procedure...

Re: SQ4 Upper chain guard puzzle

Thanks Simon - I'll call Drags today and if they realise they've sent the wrong one I'll post back to save you the trouble. I think it is clear that it's wrong from the pictures in earlier posts and your blog.

Cheers,
Bernie

Re: SQ4 Upper chain guard puzzle

Thanks Simon, yes I can see what you mean - I'll phone Drags tomorrow, they may have sent the wrong part but I've nothing else to compare with so if you have a close up pic that would be great.

Cheers,
Bernie
