Sq 4 Mk II Solex carb quandary

My "new" '53 MK II is fighting me all the way I did some fuel tank refurbishment earlier this week, and while the tank was off, I took the opportunity to replace the head nuts and spacers with new stainless I got from Draganfly. To do the job completely required removing the Solex carb and...

Clarification needed - Valve clearance adjustment

I'm a bit confused at the owner's manual instructions for adjusting the valves on my '53 SQ 4 MK II. First it gives the clearance of .006 and .008 for intake/exhaust, but then follows up with instructions to set one piston at TDC and then set clearance on an opposing cylinder at .010? When I got the...

my '53 Square 4 back on the road after multi-year slumber

I am just finishing a "sympathetic" restoration and recommissioning of my recently acquired SQ 4 MK II, which hadn't been run for at least 2 years. I've added a Morgo pump (good call, as the original I pulled off was seriously worn. she rides beautifully.. very solid, lots of low end torqu...

Re: Sq 4 MK II massive oil leak

Thanks Paul, the seller, who turned out to be a difficult man to deal with in the end, did claim that he rebuilt the engine some 2,000 miles ago, and supports it with Dragan invoices for pistons, rings, bearings, etc. I'm well aware of the concerns about clogged oil passages, but I do feel that this...

Re: Sq 4 MK II massive oil leak

Thanks to all of you for the suggestions regarding my oil leak, And the prize goes to those of you who suggested a wet-sumped crankcase. At your suggestions, I pulled off the sump plate this morning, and damn if almost a quart of oil didn't come out of there.. nice, clean, non-sludgy oil by the way....

Re: Sq 4 MK II massive oil leak

Thanks for all those useful suggestions. I am going to go with the wet-sumping idea first.

Sorry to be so ignorant, but where exactly does the crank vent exit the engine?

Sq 4 MK II massive oil leak

I just got delivery of my new (to me) '53 Sq 4 last week. The transport driver mentioned that the bike had leaked oil all over the floor of his rig, and then while the bike was sitting in my garage waiting for a new petcock, there was a pretty decent puddle left under the bike. according to the sell...

Re: Chrome Mudgards?

here's my bike. I'll admit the painted surface looks more correct, but for the time being, I bought this to ride and enjoy. I'd rather spend my money on new wheels and spokes, as well as the huge order I've just placed with Draganfly.. new engine-to-tip exhausts, most all new stainless hardware, etc...
