So longer than the LDR!

The speedos i use are made by Sigma, some are very flash and will give 0-100 mph times and many other things, a bit over the top on my 1932 side valve!

I wouldn't weld it, rather difficult to drill afterwards, never mind tapping it. It may be the thread on the adjuster, take it apart and find out! original thread is 5/16 x 26 Whitworth but CEI is close enough!

Drags make theirs from 1mm copper, 1.5 will lower your compression ratio by probably .1, so I would mill your copper sheet down a little as you will need every last horse power.

The site is working again, apparently the PHP version was upgraded to 8.1 but there was a problem and it has now been changed back to 7.9. All fixed.

Warning! Some cycle speedos only read up to 100 kph (62.5 mph) so are a bit slow for our high speed machines, also I have been told that wireless ones can have problems with HT interference. There are some nice ones made for motorcycles.

Have you contacted Draganfly, I will anyway as Iain lives across the road from me. He has been struggling with speed of the site for some months, even paying professionals to have a look and for a couple of weeks it ran at normal speed but seems to be back to slow now.

I can't see why not, although the level plug is rather small so there is likely to be a delay between the fluid reaching that level and it starting to dribble out. I would use EP90 and see little if any advantage to using semi-fluid grease

it is very possible that someone has changed the shaft, especially if it has been used in a 1956-58 machine and the clutch has not been rubbing on the primary case. Best to measure the mainshaft as Paul suggests, the shafts are interchangeable.

A quick check in the parts book would tell you that there should be a bush. It is certainly repairable by welding and machining, a used case would be cheaper and easier.
