Suzuki GS250 problem

[straggler]

Not the usual bike for a long trip I know, but a US based friend has very kindly offered me his Suzuki GS250 for a 2-3 month trip (I'm based in the UK). The bike had been standing for a while and on starting is leaking oil around the clutch pushrod. The seal has been relaced but it's still leaking. There's also a lot of free play on the shaft. Any ideas?

We were wondering whether there's another seal further inside the motor or whether we're missing something painfully obvious.

I'm flying out on 31st July and will be well and truly stuffed if we can't get this sorted, so any help gratefully received.

Thanks for looking, Richard Smith
