SQ(ueek) 4 !

I've now put around 50 miles on the SQ4 since the build and sorted most of the snags. So far so good but after the last short run I can hear a distinct squeaking/squealing sound when idling. It sounds as if it might be the sort of noise a dry bearing could make but I'm not sure where to start lookin...

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

Thanks Paul, that's very interesting - anything that reduces the level in the sump would be good so I'm wondering if it might be possible to crimp something around the pipe from below after removing the sump plate.... or stretch a piece of silicon tube over the end. Food for thought!

Cheers,
Bernie

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

In the end I didn't send the pump off to Morgo as I did my own simple test that seemed to show all was well with it. Similar to what I'm proposing now, I first disconnected the return line and diverted it into a measuring cylinder, ran for 30 secs and recorded the volume of oil returned. This was wi...

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

It's been a while so I thought I'd update. Spent the winter working through a snagging list including fixing the dynamo, investigating oil leaks and attending to carb issues. Put a few miles on the clock when the sun shone yesterday and no disasters but.... still lots of smoke once warmed up and par...

Changing the clutch sprocket

I decided to try the Drags 40 tooth sprocket on my 56 SQ4 and ordered the part which comes with new dowels for attachment to the existing chainwheel hub - Drags don't supply these. However, all attempts to press the original dowels out to free the hub have failed and I'm now wondering if these are a...

Re: SQ4 primary chain slap

Many thanks for your suggestions. It's a recent rebuild and the chain is new and all rollers appear to ne present and correct. However, the gearbox and clutch parts have not been renewed so it could be down to wear. I did notice that when I deflect the primary chain to check tension - with the gearb...

SQ4 primary chain slap

Having removed and replaced the primary chain case as part of fixing some oil leaks I find that I now have an occasional loud slap or banging sound when running with the bike on the rear stand which seems to get worse when the weight is on the wheels. If the primary chain was loose I can imagine it ...

Re: Re Electronic Ignition for squ 4's problem

Hi Keith et al. Just like to say that I really appreciate all the info in this topic as, having just built my Mk2 from long neglected parts the generator isn't working.

I've been wondering whether to pay to have it repaired or use the money to go for the 12V option and then EI.

Cheers,
Bernie
