Timing conundrum?

[Sye]

I have rebuilt the engine and ensured that the three timing dots line up on the gears, in fact I've stripped the right side off and double checked due to this problem.

I find TDC on the right cylinder, then go back a touch until the timing pin (a 5mm bolt) slots into the timing hole in the crank. I then check the R/H points with a tester and they are live. I try to back off the timing by rotating the inner plate on the generator until the timing light just goes out as per the manual. No matter what I do I can't get this to happen. I've even slackened off the generator itself and turned that but even with adjusting both I can't get the timing right. Am I doing something wrong or missing the obvious.

Confused.

Afraid i cannot offer anything positive just hoping you get a good response as this topic is next on the check list before i go for a first run, and it would help me greatly.

This method works for me.

I set the points for the L/H cylinder to the correct gap on the heel of the cam at TDC, then the R/H points the same. With the spark plugs out and the bike in 3rd gear I rotate the rear wheel in a forward direction and with the ignition on, when the points open with a good battery fitted they crack or you could earth a spark plug for the same audible crack.

As the timing is close I turn the generator to achieve the correct timing of the L/H cylinder crack to the pin slotting into the hole in the crank, this should be good enough to have the engine running. To get it really accurate I'd screw a special DTI that I have down the spark plug hole and measure the DBTDC as written somewhere and then make any adjustments by slightly moving the points for either cylinder and then checking the points gap again.

I found this works for me but I'm sure other owner's have their own method.

We have lift off, thanks Lee it worked.
