Static timing Z650

#1 PostAuthor: Oggers » Mon Sep 21, 2020 3:15 pm

A check on the static timing revealed the F marks and the indicator/reference mark to be very slightly misaligned. I would say both F marks are around 1 to 1.5 mm to the right of the indicator when the lamp illuminates. Does this mean timing is slightly retarded?

Is it wise to get this spot on, or is such slight deviation acceptable?

If both sets are out the same direction and amount just turn the timing plate.

Hi Warren

Since sorted. Bit of a dumb question really. They should be spot on. Timing plate was at its maximum travel in the slots so couldn't turn it any more! Since fiddled with each breaker plate and managed from there.

What I was getting at is if accepting dynamic timing with a strobe is the best method of setting the timing, I wonder if you could work from the aligned static marks to compensate for the breaker plate adjustment you may have to make when using the strobe?

I always set the timing plate to mid slot. Static set the points then use a dwell meter to get the exact dwell. Never needed to use a strobe, or at least I haven't since I ran over it in the car :oops:

Yes - I reset it to mid slot then adjusted each breaker plate. Never used a dwell meter, nor really a strobe much either to be fair. Some say that if set statically correctly there is not much to be gained from fine tuning, others swear by it. As aforestated, it does run well and I don't rev the proverbials off it. Maybe one for a rainy day...
