leak down test

[banshee x]

I tried 6 psi and it held with no fluctuation for 2 hours after about 3 1\2 hours it dropped about a needle width.I have sprayed the entire engine with soapy water and found no leaks even the flywheel side crank seal. Am I in the clear????

You can get a squeeze bulb from a hospital/home medical supply store (blood pressure bulb). They run in price range from $15-20 usually for a bulb. Otherwise you'll spend $25-30 to buy those parts and visit 3 different stores. I typically charge $40 for a 250r kit, $50 for banshee, all brand new parts.

expandable rubber freezplugs work good to seal the exhaust ports. any auto store sells them for like2 bucks.
