Then I ran the bike up and went to ride it back up the slope...... but the clutch was stiff as buggery 
In fact it wouldn't pull in at all 
After a bit of phaffing around - sprox casing off..... It turned out that where I had routed the cable, it had been touching the exhaust & even though it has a spring round the case, it had melted away & must have gummed up the cable, through the spiral outer metal sheath
Thats one brand new clutch cable shagged then
