engine help plz

[tomoracle290]

i went over a jump last week and landed it up side down.
I went over and turned it around but when i did it was reving its head off and now when ever i start it up it revs like mad. but it is a weird type of rev as it sound slug ish and no power.
I have a motorbike and i would say that it sound like it is getting air in the engine between the carb and piston.
I put new valves in the carb but that didn't help and thats about it.
What do you lot think.
I am going to take the engine out and have a look at it for cracks or chunks missing :shrug:
THANKS
TOM

sound like you have an air leak some ware.

i just took the engine out and the right hand mounting had a crack straight through the middle and into the casing.
I am taking it to a welder to moz to see if it is fixable

good luck on geting it fixed. if it can't be fixed by welding then you can get a new case or get a more powerful engine.
