Is there an easy way to test for charging ?
Oddjob:
I've got an old gearchange off a 400 lying around waiting to be experimented on Ted. Can't believe the amount of play in the rose joints, both have around 3-6mm of play. I'm going to replace the rose joints with better ones, replace the rubber boots with new, refurbish the gear lever and the mounting part and have it rechromed to see how it looks after.
If it looks ok Ted I'll let you have it for road testing if your up for it. Nothing worse than pulling the old foot up to change gear and you end up lifting the entire foot off the footrest because there's so much play in the linkage. Really bad design by Honda, simple lever like the 500 would have been much better.

Well that's a coincidence the none DS gearshift lever I have is rather inadequate. I might have to put my old one back on as it wants to catch the rear suspension shaft end bolt thread. I've tried a some different rod adjustment lengths and moving a spline but its not great.
So yes I'm up for testing - if its better than what I have I'm sure we could arrange an adoption fee. Thanks Ken

It's hitting the swinging arm pivot bolt Ted? Jesus, how knackered is that?
Been many a year since I worked on a 400, can you put a pic up of the arrangement Ted so I know what I'm looking at. I can't seem to visualise what it's hitting for some reason.
This is the 1300 gearchange after I modded it. 2 new rose joints with oiling points under the boots, new phosphor bronze link shaft, new stainless steel locknuts on the shaft, one left handed thread. Anti tamper stainless steel torx bolts in case anyone took a fancy to it ::) ::) Not shown is the new Phosphor bronze pivot bush
The 400 one should look similar, same rose joints, same boots but I can't get the bronze linkage bar made as a mate did a few of those for me and he's since left the firm he made them at. The 400 linkage bar is really small, only about 60mm end to end. That bar is 100mm so too long, shame as I have a spare.
Oh a top down view of the gear lever would help Ted, I think the lever is bent where the gearchange rubber fits, need to see how a straight one looks so I can reshape it back to original spec.

Those regulators are pretty bomb proof Ted, normaly takes a lump hammer to damage them! Nothing electronic inside just coils, resistors and points which dont mind reversed voltage.
As an asside the only difference on a 500/550/750 one is the angle the terminals point at

This is the replacement unit I bought from Bertums as my old lever was well rusty.
This is to show the bottom where it touches the end of the thread of the long shaft - it clears the nut but just touches the end thread. Second photo shows the clevis pin that it just misses now I have fiddled with the adjustable rod. Even the new ball joints seem to have a lot of unnecessary movement before they do anything. It was a lot cheaper than the DS replacement so I've part learn't my lesson
