Boyer Ignition

[star15]

Did i once read on this forum that you have to have a fully charged battery for starting your bike, i have been trying to start my Bonnie after a long rebuild, it gave a few bangs but not much else, i am charging it now as i wright this, it was sparking the plugs, but it shows a little low on the charger, new Mikuni carbs as well.

It's lucky that Hooli is away from the forum at the moment !

AFAIK your Boyer does need a fully charged battery to work correctly.

Has the bike ever run on the Mikuni's ?
It's never a good idea to have too many unknown quantities at the same time.

The bike has not run since i bought it, it was a half started project, i will recheck every thing, also had a bit off a petrol leak, got some new dowty washers, but no good, i tried to tighten them up, but i know from before they can snap like carrots, these pattern taps, might try some ptfe tap on the threads, hope that will sort it. The bike has a lot off knew stuff, boyer ig, power box, mikunis, half race cams, hyde valves, gas flowed head, tt pipes, might get to look at it later.

It needs a fully charged battery to get dependable starting with a Boyer.

After fully charging battery and much kicking over, still no joy, then a while later after much head scratching decided to swap wires over on the stator plate, 2nd kich i did not think it matterd as it runs a wasted spark. The only thing now no oil, i have fitted new morgo rotory, think i may have to bleed it, i have also fitted a hyde oil cooler, so there is a lot of pipes to fill, job for next weekend.

Early versions of that super oil pump blew the creankshaft oil seal inside out, unless the pressure relief valve was drilled with extra holes. As you have also found out, they don't self prime. I think mechanical disaster is inevitable, eventually. Did you throw away the Triumph pump?

Boyer - urgh!

They default to max advance if the input voltage is low, which will result in nice kickbacks through the starter when you try to get the bugger working.

I wouldn't worry about the lack of oil, the boyer will die before the bearings
