GP200.

.....New one was put in on saturday, rode well up to Coventry 65 miles but on the way back engine was revving on hills as if the clutch was slipping, got worse in all gears and i was down to riding at 30mph.. I loosened the clutch cable and it improved a bit. Did this 4 times over 15 miles and it rode much better although at 50mph the engine was racing again without the power. Is it as simple as the clutch cable requiring adjusting?

Kick start shaft hasnt slipped in slightly, have had that before. Are some good clips and washer out now to help spread load over the outer seal.

frayed cable not allowing the arm to release the clutch dodgy springs or plates, pos cush drive on front sprocket or centre bolt not tight

Had the same problem myself last week once i hit a certain amount of revs. Turned out that the clutch spider was slightly twisted. Did a fair bit of damage
& the chain was just about ready to split in half Is it a complete new engine or just the clutch

check oil level too much will make it slip aswell.

Three of us were watching when we did the oil, cables are quite new and nylon lined,.....i'm not mechanically minded and can only think logically... .........so why the improvement when i adjusted the clutch cable.............. ...........appreciate the replys....

perhaps the cable was too tight to begin with ,I am not saying this is the case but have seen cases where the clutch has been adjusted to make the gear change easier but then it slips because the cable is too tight not allowing it to release fully, worn lever give a false sense of freeplay in the cable. if this is the case you need to tackle the main problem which is normaly not enough movement of the clutch arm ,
you can shorten the clutch arm
file the lever and or housing to move it further from the grip ( only if you can reach the lever at its new position comfortably)
fit thinner corks or steels to allow more room for seperation
whatever the problem I think you need to open it up and have a look

Cheers, i'll let you know how i get on over the weekend..............
