[sparky]

Hiya All just seen your great looking site thought I'd look in and ask a question if I may..
Just done a complete rebuild on a 1967 tri T100T and for the life of me cannot get the ign timing right to fire the bike up, have tied 19deg & 38deg on the camshaft via timing disc (tri type) it has boyer ign set up with a good spark so can anyone give me a detailed how to do it as the haynes & old tri manual aint working for me.
Cheers all Dave

Set the crankshaft to 38 degrees BTDC, and then put a paint mark on the alternator rotor and stator next to each other, then turn the (loosened) Boyer rotor so that the white dot on the rotor magnet lines up with the lower hole (for clockwise rotation) in the pickup plate, when the plate is positioned midway in its adjustment slots.
Fully tighten the rotor and nip up the pickup plate screws, as the engine has to be started and revved to 5000 RPM to strobe check that the alternator marks line up at those revs.

Thanks for the replyFound out the above and the bike is now running but not sure about reving the bike to 5000rpm to strobe as it not run in and a brand new engine. cheers Dave

not sure about reving the bike to 5000rpm to strobe as it not run in and a brand new engine.

That concern does understandably get raised fairly often, as owners are reluctant to rev a newly rebuilt engine to 5000 RPM, but the general consensus of opinion is that it doesn't do any harm, provided that the 5000 RPM checks are brief, and the engine isn't allowed to overheat. Otherwise, do it as soon as you think it is safe to do so.

If you run the engine up in your garage or workshop, always have a fan blowing on the motor to keep it cool.
