Did the bike seize? If it did I'm afraid he will have damaged the bore, if not, fill the two stroke tank up (should be using fully synthetic) and remove the bleed screw, (on the pump)and twist the throttle. Wait and see if anythig comes out.

Whether it does or doesn't, put an egg cup full of two stroke oil into the fuel tank and shake the bike to mix it.

Start the bike and you should start to see oil running out of the bleed hole. Leave the engine running on tick over until you CANNOT SEE ANY AIR BUBBLES IN THE OIL running out of the bleed hole.

What area of the North East are you from. I recognise the name in your profile.

Cannot rebore.

Google for Stan Stephens. There is a bleed screw on the oil pump.

I had my enduro bike, barrel re nickoselled at Bike sport 0191 2328970 £120, new piston £60.

That was three years ago.

Try bike shops local to you as they will know places,cheaper,nearer.

Use genuine parts only or better.
