Hi all,
A bike I bought a year ago is fitted with a Boyer Bransden electronic ignition. The bike starts easily, ticks over well and seems to have the sort of urge I might expect in the lower and intermediate rev ranges. Carburation seems spot on by the colour of the plugs. The bike seems unwilling to reach maximum revs and the top speed seems to be no more than 80mph.
I want to check the ignition timing, Because it is electronic I am going to have to use a strobe light (for the first time). Can anyone advise what the degrees figure is fully advanced BTDC? The book I have assumes static timing only. (9/32" BTDC)
If anyone else has fitted electronic ignition to a Dominator 99, what product did you use. I was s bit disconcerted to find that the kit fitted to my bike is for a BSA/Triumph. I am wondering whether it is retarding as the revs increase instead of advancing?
Any help or advice gratefully received.

Regarding timing..out of curiosity, which manual do you have? My Haynes gives 32 degrees. My F Neill also has 32 degrees, as does Bacon.
Since the plugs at 30 degrees off the vertical, piston drop gets complicated to calculate and to use.
If it gets up to 80 and no more, main jet might be the problem. Are you certain the throttle and air slides go all the way up?

When fully advanced the timing should be 32 deg. which probably equals the 9/32 advanced setting you (mistakenly) quote as the static setting.
