Picked up from a bike shop in Los Angeles in poor condition trucked it down to San Diego and have revamped most of it; waiting on the top end from the machine shop. Had it running briefly before it started burning oil due to scoring in cylinder one. 9.5:1 .060 over rebore is soon to be assembled.

That should be a real nice "before & after" photo!
Thanks GrandPaulZ. Its definitely not a period correct resto obviously but I think it will at least not be burning white oil smoke out the drive cylinder. And, yes I will next month possibly have a b4>after photo or mp4.

Diagnostic 101... what works. what doesn't. Finally resolved the always on brake switch issue after much confusion. The tr6r now has functional lighting (until one of the bullet connectors comes loose on the road.) How cool it would be to convert the entire loom to Deutch Pin water proof connectors.

Hi,

until one of the bullet connectors comes loose on the road
Curious, I always use standard 3/16" OD bullets, never a problem in over thirty years. "Diagnostic 101":-

. New bullet terminals like this:-



... are sized for metric strands (0.3 mm. OD); otoh, original Lucas/Triumph strands are a slightly-smaller (0.274 mm. OD) No.32 (British) Standard Wire Gauge; collectively in a wire, it means a 'metric' bullet doesn't grip original strands as well. :(

. New bullet terminals like this:-



... used by pattern part makers :bluduh - are commonly 3.9 mm. OD; as I say, original bullets and snap connectors are a nominal 3/16" (4.7 mm.) OD and ID respectively ...

. The steel sleeve inside some old snap connectors can split lengthways, especially if it's squashed around a 3.9 mm. OD bullet ... the insulation holds the split sleeve together but the sleeve doesn't grip the bullets in each end as well. :( Any doubt about old snap connectors, just replace 'em.

How cool it would be to convert the entire loom to Deutch Pin water proof connectors.
Mmmm ... about '73, Lucas had this brilliant idea they'd use something similar - AMP connectors. In reality, absolute disaster, because there wasn't any way of tightening the sockets once they'd been 'sprung' being fitted over the pins. :Darn Lucas reverted to bullets and snap connectors a few years later; as I say, I've used the latter for over thirty years without any problems.

Hth.

Regards,
