my 2 stroke scooter has the 2 stroke oil injected from oil tank

when i start my bike until the bike is warm it will blow out blue smoke from the exhaust, when it is warm there is virtually no smoke is this normall with it being 2 stroke, i read in the manuel that it might need a new piston but i have also been told this is normall for a 2 stroke bike

pulled spark plug out no oil but was all black and dry

it is normal.dont know what kind of oil you are using but Yamaha 2 stroke oil seems to smoke less than some others.

Oh yeah, that's normal.

Many synthetic pre-mix oils create almost no smoke, ever. But they ain't cheap, and frankly, they stink. To me anyway.

Now the smell of Bel-ray..... that gives me a chubby.
