Thanks Graham a very informative video.

Not a big criticism but I would not have used an adjustable spanner to rotate the crankshaft - the right sized spanner might be more appropriate.

Also it is good practice to use a independent battery for a strobe light  ;)

Good point Graham,  I used  my garage slave car battery  when working on my 400 simply to make easier use of the lead lengths & avoid flattening the bike battery.

Good video, that's pretty much how I set them up except I use a battery and a bulb, here's my high tech gear.


Cheers

That's a more accurate setup in reality. Notice how the yt clip guy struggled with the light glowing ? That's because he is still switching the coil load through the points and you can see the earth route going flakey as the points come off contact with their faces and the 2/3 wuth it's backplate while screws were undone.

With this and routed through disconnected coil wires, then the load for the bulb is tiny and more easily read.

Also the same with "bleep" continuity tester, as with meter and tiny battery the position is more accurate in setting, the tell tale is that he has to adjust it with strobe as that shouldn't happen if done accurately.

The setting for 2~3 points is just compensation for production tolerancing on the points mechanism itself as the crank firing is exactly 180 degree apart, so once set..... for those points in use......it doesn't change much. Wear on pivot and points heal the reason. Grease on cam should be replicated on points pivot.

I would not use ANY spanner on the advance nut to turn the crank unless all plugs were removed

It just seemed to read that way Graham, put the plate in the middle of its adjustment and then use the point gap to time it up is how I read it

Any mention of a atrobe means timing to me, dwell meter would mean gap

Maybe you should pop around and show me how to set up points. Maybe my strobe light is no good. You could advise me on if i need a Hondaman box of tricks or that i need to change to electronic ignition. while you are here you could advise me on how to rebore cylinder's, insert valve guides, change valve seats, re grind valve seats to the correct spec, skim heads, alloy weld cases and do fin repairs and so on.

 
I would love someone to be able come and show me how to set the points and timing properly. But if there's a good tutorial (vid or other) somewhere that can be recommended in all ears!

P.s Hackaweek was my original YouTube tutor so I used his technique


I have been looking through a ton of youtube vids on setting points and most of them are well off. This seems to be a good guide but, there is quite a few cuts, like the plate seems to move on its own at 7.20. Hope it helps >>> https://www.youtube.com/watch?v=3933ouJ1wrI&t=924s
Nice one Trigger that's a nice clear tutorial. Bonus soundtrack too

Your points screws were sent to Roo earlier in the week. With luck he'll have them now.
