Re: FOR SALE : 1928 model E

This is one of the ex Mike Taylour bikes and was sold at Stafford in April for £7000 plus commission. The current vendor looks as if he has a nice profit margin in mind.

Re: Sq 4 rocker oil line leaks..

P.S. as the the cylinder head joint issue, you will cause no problems at all if you do the work on the pipes at the same time as you do a total re-torque of the head as you would after say 50 or 500 miles.

Re: Sq 4 rocker oil line leaks..

This joint and pipe is one of the problems on the Mk II. The original O ring seals are good for one use until disturbed and fibre washers may well perform similarly. It is possible (just) to fit 1/8" BSP unions with olive connections into the rocker blocks and use an 1/8" copper pipe betwe...

Re: What to do?

Use a white metal lined bush. Close to 20 years ago, I had cause to replace the timing side bushes in a Square and thought about the use of bronze ones. The (now deceased) old time machinist who was to do the work told me that he would not be prepared to fit bronze bushes if white metal were the ori...

Re: gb/b52 gearbox-same innards?

I find that gearchanging on a Square is different from that on (say) a single. The Square engine is much quicker to respond to changes in the throttle opening which means in turn that gear changes can be quicker. It's a matter of getting used to the bike as much as anything. A GB gearbox slipping ou...

Re: Knee grip mounting plates 1948VH

Buy the one Draganfly have in stock. The other one is exactly the same size, but curved in the opposite direction. They are pretty easy to make.

Re: GB44 Mainshaft Query

When the bike is running, oil will be placed upon the rear chain by the oiling system via the felt pad in the oil tank. This will be more than enough to keep the area you highlight free from corrosion. The FERC keeps it fairly clean from grit, etc as well.

In short, stop worrying.

Re: Main bearing in gear cover--1938 Ariel square four

Oil is all you need. But I would never start a Square Four after a rebuild without putting about a pint of oil in the sump. Yes, it will smoke a bit and throw some oil out but if you have an oiling problem such as an oil lock or the pipes connected the wrong way round it will safeguard the engine. A...

Re: Is This A Stainless Rim?

Some grades of stainless are magnetic. If you ask Acme Stainless for a wheel spindle it is likely to be made in magnetic stainless since this material performs better in this role. But it is a swine to machine.
