Air filter so I took both drain bolts out removing

The oil (Moving the bike around until stopped

Dripping & took the oil cap off) removed the old

Filter and replaced It with a new one Inserted

The drain bolts. So i Spoke to two motocross

Shops they had told it to put 1.2l oil in so

I know to much oils bad I put 1.1l oil

And then removed the air filter and replaced

The old one with a new one & forgot to grease

As I've got no oil for it Anyway fires up

Just exact same it did first second kick no problem

Let's it run for Id say 15-20 minutes put it away

For the night gets it out this morning starts it

Was fine cut it out loaded the van up get to the

Track kick starts fine revs twice and dies out

Won't start at all not even bumping still has

Let it idle for 15-20 minutes?

Idle?

I have recently removed the new ungreased air filter and pull the old one in for now until i receive the oil for it

How would I do this it the bike doesn't start ?

sounds like you killed the plug. 

What do you mean killed the plug ? As in blew the spark plug ?

He means you fouled the plug

It is possible the plug is bad, but its also possible that something may have come unplugged during transport

Right so the engine could be effected ? Or will it be the spark plug/carb ?

Make sure you have spark, then make sure it is getting fuel. If you don't know how to do these there are excellent videos on youtube.

 

I managed to break my fuel pump on my 2010, took a while to troublesoot
