Setting timing issue
ted_paper:
Sort of a follow on from condensers and points topic.
This is my first time changing points and setting the timing so I have been following Youtube videos and the Haynes manual.
The problem I am having is that the timing plate has run out of adjustment - ie when the circuit to the points is made, there is no adjustment that be made to bring it line with the F mark.
I have attached some pics which show when a circuit at max adjustment.
Am I doing something basically wrong?
taysidedragon:
Check the points gap. When set to the correct gap you may have enough adjustment to get the timing right.
Oddjob:
I gather that those are not TEC points? In that you can see TEC embossed into the base plate?
If not then this is quite common if you're using cheap and nasty aftermarket points, the price makes them look attractive but this is the result. Set them to 12" point gap and see if that helps, it usually does. 1-4 usually line up but 2-3 won't is the usual problem.
Or buy TEC points.
ted_paper:
The video I've been following suggests to to use the tang that appears in the view hole approx. 90 degree turn after the firing mark to use to find the max point opening - is this the correct way or is it just a case of trying to eye it in?
Points are non-branded from Wemoto, about a tenner each - probably false economy then?
Oddjob:
The tang sounds about right for maximum opening, the points are probably Daichi, is there a small sort of propellor symbol on the base plate of the points, just so we know that Wemoto are selling Daichi.
TEC points, which are the genuine points, are around £25-30 a set, sometimes it ends up cheaper to buy the complete base plate from Honda, especially if you need condensers as well, but those seem to be drying up these days. The best bet to protect the points is to think about fitting the Hondaman system, this changes the way the points work, the spark essentially wears them out, so the Hondaman system removes that and makes the points just act as a make/break piece with hardly any current running through them, the timing is controlled by a small electronic box. This way the points last for years and years, and the beauty of the system is that IF the electronics go belly up it's a simple 30 sec job to revert back to the points again.
It's the way I went with mine and lots of other members have too. If any of the other electronic systems fail, like Boyer, Illuminition, Kokosan, for example, the bike stops and leaves you stranded at the side of the road. Nice to see nice new screws etc on the plate Ted ;D ;D

Oh there's a small piece of felt at about 5 o'clock on the points plate, drop some light oil on it if you haven't already, it helps stop the points heel from wearing as it rubs on the advance/retard cam. Something like silicon oil or 3 in 1.
