Grumph / Tri-Greeves

[Itsme]

Hi there

That's looking really nice now, I have always had a soft spot for Triumph twins in any sort of off-road guise. The Greeves route is lovely and I remember once a long time ago a photo in Classic Bike of a 500 twin in an Enfield Crusdaer frame done as a trials bike - gorgeous. But one thing that really sets off a Triumph twin is the exhaust pipes. I've never been a fan of straight-throughs or even splayed pipes particularly, but show me a well made high-level siamese and I'm in heaven!

I'm sure whatever you end up with will look very nice as your other specials and progress on this one all look very classy.

I think I may have found another exhaust solution: flexible stainless pipe. From the same people as Bill mentioned. I'm going to pop over this aftrnoon and have a look. Cheap enough and won't look too out of place - but may disappoint Ian Itsme....

Just popped over there and it's a brilliant place who also bend pipes to your spec. But the convoluted stuff actually looks pretty good and for the price can't be beaten. So when I know lengths I'll be back there.

Good to know Ian. Thanks. Oh and thanks to Bill for posting the original link up 👍👍

Hi Ian

Thank you for your concern over my disappointment level, but let me assure you that I could never be disappointed with stainless steel.

Pleased the link was of use and from the look of it, I'd rather have the polylock flexible pipe than groovy multi-coloured, multi-welded bitsa pipe! 

Good health, Bill

I needed a rear sprocket as the Triumph uses a 5/8" x 3/8" chain and the existing Greeves one was 1/2" x 1/4". So I bought a blank 51 tooth item from Simply Bearings - they call it a platewheel - and had the central bore increased, five 5/16" holes bored, the centre relieved to miss the spoke heads and lightening holes machined in by Simon at Nametab Engineering wh're local to me. I think you'll agree that £40 was a fair price.

The other things in the picture are tapered punches I've made up in various sizes to help studs and bolts into misaligned holes.......

nice job @ a very fair price

Just finsihing off the minimal wiring. I've gone for a dual lead coil giving an idle spark which involved paralelling the points. Can you get the little special terminals? Can you hellaslike. So ended up reducing the size of those crimped on ones with the Dremel. But soldered rather than crimped of course. Getting a decent spark when flicking the points.

that picture brings back memories  stuck in a layby , in the rain, on my Franric Bastard, trying to lock  in a stripped thread on the screw that clamps the static point .... of course the silver paper from a fag packet did it in the end ... oh what fun we had 

[iansoady]

Yes indeed, I'm hoping not to have to resort to such methods.....

To be honest I've been surprised how I had virtually a whole engine in my pile of bits and how it went together relatively easily. But of course haven't tried to start it yet.

A bit more progress. Oil tank all sorted out and plumbed in (pics to follow as it's on the other side). Chain fitted - it needed a cranked (half) link which was difficult to find. Chinese Mikuni copy carb fitted - no idea whether it will work but the correct monobloc is in a right state and this was only £16 delivered from China. But the major step forward is starting work on the exhaust - this is the left (drive) side one with the polylock flexible section inserted and a "chopper pot" silencer. I did try a chrome one but it made everything else look too scruffy.

The exhaust is in place but not finally snugged down but I'm pleased with the look and I think I can see how to sort the rear brake pedal out.

The other side....

Aye Ian,

Cranked links readily available from the "The Chain Man". Link: The_Chain_Man_link

Based at Stourport-on-Severn, just a nice jaunt away for you.

Good health, Bill
