I’m building it as a road bike, I’d guess the frame is around 2/3 the weight of the standard frame. I’ll weigh the bike against a standard bike when it’s finished. I’m using a complete rebuilt front end and wheels from a 1977 XT500.I assume you are building it as a scrambler? Do you have any weight estimate for the finished bike?
Are you using the stock hubs, and what rim sizes?
The dry weight of an XT500 is 305 lb, the dry weight of a Rickman Metisse with a T140 triumph engine is 296 lb, the XS650 engine weighs around 150lb as opposed to 130lb for the T140 lump. I’m not using a starter motor and I’m using an updated combined generator and ignition system, so I’m losing a fair bit of weight .I estimate the finished bike will only weigh around 4-5 lb heavier than the XT.Ok, I read that in the start of the thread after I posted that question..Not wanting to be negative, but I suspect that the XT500 drum brake may not quite match the capability of the Metisse frame. I have never ridden an XT500, but have some experience with its little brother XT250. Which has a smaller drum, but is also a lot lighter. That front brake is not very impressive.
The kit came with six pairs of eccentric washers with holes in different positions that locate onto a pin in the frame undercut.Sure is pretty, knew a young mechanic when I was young who flattracked a Metisse Triumph. Just curious, Does it use snail adjusters for chain tension at the swingarm pivot?
Also I know others have commented, and I have noticed as well that it's often easier to lay the engine on it's clutch side and put the frame on the engine than to hoss the engine into the frame.
Learn something everyday. Thanks!I was reminded of your fantastic build this morning when this popped up on the VFT.

A little progress made, engine in, engine plates polished and drilled.I’ve just ordered aluminium round bar to make a pair of intake manifolds.View attachment 188455View attachment 188456View attachment 188457
I'm startin' to get nostalgic...
Back in the late 60s and early 70s while I was riding trails on my T100R , the hot set up for most of the guys I rode with
were on Rickman Triumphs 650s. Most built their own from the frame up like you are doing. Those were good times...
The tyres are TKC70,Like the look of those tyres - wot are they, please?
