Heres a case leak tester i made for cheap.
I had most of the stuff already but the rest is easy to get at about any parts or hardware store for under $15 or $20. I had the hose and y fitting, other fittings, and hand pump, all i needed to buy was the gauge and plug, i got those for under $10.
Now i just need to pull my exhaust and carb, put the piston at BDC, and put the plug into the ex. and the adapter into the intake. Pump the tester to 6psi and make sure there isnt any bad leaks at first. If it seems good and sealed leave it alone for 5 to ten minutes. When you return you should still see 6 psi on the gauge, if not pump 6 psi back into the crank case, then spray soapy water around all mating surfaces and look for bubbles. Bubbles equal leaks, leaks equal poor running or an erratic hard to tune motor that may lean out at any time causing damage.

. Im gonna make some adapters for different intakes and exhausts. I think this would be a good thing to use after assembly of a new top end or after putting the case back together. Its peace of mind knowing there isnt a leak. I hate leaks!
