No pics of it hooked up but here is one I wrote up a while back. Might be able to help you out since it was written with some of the kawi stuff in mind... At a bare minimum you'll have to pull the carb and exhaust pipe off. I prefer to leave the manifold on the cylinder as those can create leaks as well.

A quick and simple way to seal a motor get an old innertube from the tire shop and use your gaskets to make a solid rubber gasket out of the innertube and install that and then bolt your carb or exhaust back on. I bought a set of those hollow hole punches from harbor freight and they work perfect for this. I can make a set of gaskets faster than cleaning the carbon from the exhaust manifold to get the test plugs to seal.

Great idea, now how would i get the air into the bottom half of the motor and measure it???


Thanksssss

After the motor is sealed plug your pump into the pulse line that goes to your fuel pump. I always spray the motor and the pump down with soapy water while doing it just to make sure that if there is a leak I know where it is.
