Didn't like commercial leak down testers; they were either grossly overpriced or too cheap to trust, and I didn't care for the lack of filtration on all of them. So I made my own.
The tester is based on a Sears regulator-filter unit. Is it ugly and bulky?Yeah. Does it yield as clean, accurate, repeating comparison of pressure in to pressure retained as anything you can buy? You betcha.
Leakdown testing procedure doesn't involve deep tech knowledge, but even most seasoned owners should do some homework before they attempt it. If your experience with leakdown testing was gained with 4-bangers, be very aware that hitting one cylinder of a twin with standard test pressure of 100 psi is going to move that motorcycle if it isn't locked down tight.
Same conditions as before: payment accepted by mailed check only, reductions down the road won't happen, no trades or "offers" accepted, ad down in 10 days if nobody wants this.
