Motion Pro Leak Down Tester With this whole healthcare debate (no, I will not be getting political here), we've heard a lot about preventative care. Everyone knows it's a good thing. You nip a problem in the bud, and you end up with fewer troubles in the future. The body is little more than a machine, albeit a squishy, viscous machine, so it's not a surprise that preventative measures work just as well for you bike as your bod.

Motion Pro's 4-stroke leak down tester is a diagnostic tool for preventative care. This, along with an air compressor that you'll have to supply, will help you check your rings, head gasket, intake valves, and exhaust valves. By sending 60 psi into your engine, the tester will tell you where you're looking pressure.

In a best case scenario, you'll learn that all is well in that thumping engine of yours. In a worst case scenario, you'll be able to replace a gasket before it leads to problems that could leave you stranded.

The name should tell you that this is for 4-stroke engines. Motion Pro does carry leak testers for 2-stroke as well. Motion Pro's tester is equipped with 10 mm, 12 mm, and 14 mm spark plug thread hoses. It also comes with instructions, so you won't have to turn to dubious sources on the Internet.

This tester runs at around $150. Some of the more industrious among you might be thinking, "Hey, I could build one for $50." I say to you, have at it and good luck. For myself, I'll have enough work fixing any leaky bits on the bike and don't want to risk a false positive that has me ripping apart my perfectly good engine.
