have been doing just that Kit, when I finish work I just decide not to go near the shed some nights.
I did remove the whole points system and replace all the wee adjusting screws as they had all had their tiny little it ti bit ti threads TOTALLY MANGLED BY SOME CROMANGON!!! but enough about my lack of finesse with a screwdriver.
Jaffa's bike is one of those anomalies, it is part way between the era when the GSX400 had it's points replaced with PEI (CDI) and the cam chain system was altered for whatever reason.
So she has the modern cam set-up but the older points system, I need to refer to the 81 manual I bought for the points and then rush inside to check the manual I downloaded for the cams...most vexing.
Anyhow while I dither, Jaffa has been getting on with the paint job, God this thing looks girlie!
