Yeah it's all standard, if i was to take this to a shop to be fixed how much do you think i am looking at?

I would strip carb down and fit new air filter. Is it standard?

Hhm, it does seem to eat fuel like candy.

prehaps a fuel or ignition problem.

When i start the bike and rev black smoke comes out for abit and then it takes it's time to move. then it actually goes bit about 5-10 minutes down the road i'll have full revs and it'll just stop. then i can let go of the revs and wait a few moments and it'll go again but it'll do the same thing again. Always has oil and lots of fuel in it. It's also generally quiet when i start it up which is rare as peds are noisy. :O

it doesnt sound good does it slow down and then take a while to start again?it may be seizing up !other than that it may have a fuelling problem does it make any noises when it stop and is the kickstart hard to push down or stuck for a while after it has stopped?is there plenty of oil in the 2 stroke oil tank?
