Hi. Well today I managed to fit a new front tyre to my 247, the first tyre I have ever fitted on a bike. It went OK.

My next problem is when i put the bike in gear it tries to move forward so i have to keep the brake on. How easy is it to put a clutch in these and do you need any special tools. Could it be that the clutch cable has just stretched?

Well done on getting the tyre swapped - it's all too easy to pinch the tube with the levers if you're inexperienced. On the clutch problem, probably the plates are just stuck together. If you've got some space available, knock the bike into gear and hold the clutch lever in as you change up through the gears. The torque of the engine should break the "stiction" between the plates by the time you get into 4th or 5th gear. The bike will then operate normally if this is the problem.
