Using a lot of 2 stroke oil after rebuild ?
just finished top end rebuild and fitting new power valve , so Good news bike is running and went for a quick 5 mile ride and even though running in it is a lot faster and power valve really makes a difference to bike.
Bad news 2 stroke oil went down 4 inches from level of top up (pencil line) smoked like hell of course,,I have not touched oil pump so any clues to the problem would be helpful.
Oil pump could have failed. What caused you to do a rebuild in the first place?
Your pencil line could have been incorrect or bike not level.
Be sure to brim the 2T oil to the top. And repeat. If after a 5 mile ride it has used excessive amounts of oil then you have a problem.
The bike should smoke a lot if you've done the rebuild correctly and used plenty of oil. It may take a while for the smoke to stop depending on how much oil was used. I use lots but my engines stand still for extended periods of time.
@Calum The bike had been stood for 1.5 years when I bought it and so after cleaning out tank , also doing a lot of simple maintenance like exhaust very loose from cylinder etc, it ran but badly seizing after 50 miles ( compression was low from the get go 75 psi),
so Re-bore new piston and rings also power valve fitted as did not work when I got it, it did not even have an air filter when I bought it only 6500 miles but treated like a rented Pony as they say,
But in the 50 miles I rode it before strip oil was not a problem, also I arked level with bike level and level dropped 4 inches in 4.5 miles, hence my question
