I forgot to mention, there is another issue with the bike, there is a piece of metal on the rear sproket and it is held on by 2 bolts however one of the bolts has disintergrated which made the piece of metal get trapped in the spokes until i bent it back. What is this? Should i replace it?

Thanks for the prompt response. If it is stuck open is this a sign that the valve needs replacing or cleaning?

Hi there, I have a PW80 which is using lots of fuel. There is a thin plastic tube running off the carb and it seems to be losing lots of fuel via this. Any ideas? Thanks
