It's not the chain slipping Pete, it's the freehub not engaging. You pedal forward, the cranks spin but the wheel doesn't & the freehub/cassette turns. Then it works fine again for a bit, plus it does it when the bikes stationary.
I think I'll just try to double chainwhip the cassette off, remove the axle & freehub then see if I can flush it through. Hopefully it's just dried up grease like inside the brakes & shifters.
Thanks for the info on the Suntour cassettes & microdrive stuff
The serial starts 0293 so Feb 93.
The self energizing brakes had me stumped for a bit as one side had loads of tension, the other side none. Realized they slide down on themselves & one side had seized, sorted that & they work now.
The Pace forks still work & rebound back, stem seems Ti like the bars but the welding is not too neat on it, campagnolo hs again was fine with a bit of grease.
I think I'll put some off road tyres on it, take the bar ends off & put a decent saddle on. Then take a couple of pics before I give it back to him.
