For the latest 4WD Mechanix Magazine Off-Road Motorcycle HD Video Channel HD videos, see the playlist below:   

Setting piston to TDC for cylinder leak down test

     The magazine launches "The Off-Road Motorcycle Channel" with this engine diagnostics and troubleshooting how-to video. Moses Ludel discusses cylinder leak down testing, as he pinpoints the low engine compression source on t he magazine's Honda XR650R motorcycle. In this HD video, learn how to perform a cylinder leak down test on any internal combustion engine and why this is a superior diagnostic tool!

Cylinder barrel removal during upper engine rebuild

     In this two-part HD video series, Moses Ludel rebuilds the top end of the magazine's Honda XR650R motorcycle engine. Here, "Part 1" covers the step-by-step tear down, including cylinder head and cylinder barrel removal. Low compression led to this tear down. (See the HD video coverage of the cylinder leak down test.) This tear down leads to subletting the cylinder head and cylinder for machining, head work and cylinder reconditioning.

L.A. Sleeve cylinder liner and rebuilt head assembly

     The magazine's Honda XR650R motorcycle came with very low hours on the bike. Unfortunately, the air filter had been sealing badly, and the result was an engine with damaged valves and excessively low compression. We turned to L.A. Sleeve Company for its Moly 2000 iron/chrome-moly alloy cylinder sleeve and cylinder head rebuilding. In this HD video, see what it takes to build an ultra reliable cylinder head and barrel at L.A. Sleeve Company. This bike will be used extensively as an HD video filming platform, and our aim is maximum dependability in remote backcountry!
