Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Endeavour kickstart bent

The kickstart to my Endeavour is obstructed in use by the (non original) centre stand. It has been crudely repaired and welded at some stage and appears to be misaligned. It is difficult to see from the photos attached but the U bend relative to the spline end seems to tip backwards.
Might anyone have photos or a drawing of one in better condition (or of course a spare - unlikely!). Thanks, George

George,

I have one kick-start lever to share between two Endeavour projects (see attachment). However, it does appear to be unmolested so I can use it as a pattern. I will dig it out of storage and get some measurements.

The kick-start pedal fitted to the Lofty Daniell Endeavour ohv special was altered as part of the foot change conversion.

Could use help with some info on the inlet manifold and oil pump.

...once I find where I put the blasted thing!

Doug, your one certainly looks better than mine!

I'm happy to help you but have not got as far as the engine yet - it turns with some compression so my plan is to check the timing then see what happens....

My bike, possibly the earliest production Endeavour, had been somewhat kicked about and modified over the years.  I am trying to get it back more or less to how it was when first built but not as a concours example. Among other thing I have had the tank renovated, found the right instrumentation, completely rewired it, cast new alloy silencers, renewed the handlebars and put on inverted levers, made up a front brake rod, fettled up a crash bar and rear hub caps, renewed the rubber drive donut and made up a n/s toolbox.  I'd like to have the original Douglas type twist grip throttle - if anyone has any bright ideas on this?

Slowly getting there!

Regards, George

George,

Took a little time to find the little devil.

There seems to be a slight kink as indicated by the arrow (1st image). However, the peg is bent slightly ground-ward so I cannot rule up this slight kink is not also a by product of a heavy boot and a long kick start pedal.

Looking from the edge (2nd image) it initially seems there is just the one offset joggle ad the remainder lies on a common plane.

But... stood up on end (3rd image) the offset does not seem to be parallel, but at a slight angle. At the bend it is 11/16 of an inch from the back face of the hub.

Shimmed up with the hub flat on the table (4th image) near as I can get it, and the lever arm does seem to be on an incline, as noted by the dimensions. This would be in the direction it would twist from 'heavy foot', so I am inclined to think it is not design intent. I think it is intended to be square to the transmission/chassis.

Give me a few days to knock up a drawing. This will if nothing else be insurance against misplacing the kick start lever again. Meanwhile the attached photos might get you started on a plan of how to correct yours.

Thanks Doug, that is very helpful, especially seeing the amount of offset after the slight bend at the spline end.
I think that the peg on mine is more or less at a right angle to the lever - so your 'heavy foot ' theory is probably correct.
