Setting piston to TDC for cylinder leak down test 
      In addition to the mobile website, the magazine launched "The Off-Road Motorcycle Channel" with this engine diagnostics and troubleshooting how-to video. Moses Ludel discusses cylinder leak down tests as he pinpoints the low engine compression source on the 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  

     Moses Ludel rebuilds the top end of the magazine's Honda XR650R motorcycle engine in this two-part HD video how-to series. 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 magazine's 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! 

Curious how this iconic and "bulletproof" Honda XR650R motorcycle engine got to this wear point in less than 1000 original miles? Get Moses Ludel's comments on carburetor jetting, air filtration and exhaust—exclusively at the  4WD Mechanix 'Tech & Travel' Forums—click here!

Time-Sert® spark plug thread replacement method 

     Spark plug thread damage is increasingly more common due to the popularity of aluminum cylinder heads on automotive and OHV engines. View the short trailer (above) or click here for a full-length HD video how-to demonstration of the Time-Sert® permanent repair of damaged spark plug threads. The insert kit allows for head-in-place installation of new spark plug threads. Our candidate (at left) is a popular Honda XR650R motorcycle. The affordable repair saved considerable time while providing a major improvement over OEM spark plug threads! This also works on over-the-fender automotive engine repairs.

"In response to your reply, Moses, I'm mind blown...It will take me a couple reads to soak this all in, but once again, mind blown. I wish you were my neighbor!"—Member Megatron

"I first read Moses' writings when I bought his Jeep Owner's Bible years ago. I joined the forums to solicit advice on my cylinder #1 misfire. My mechanic advised replacing the motor due to the 250k mileage. Moses started with fundamentals, rather than part swaps. And other folks here have chimed in with additional advice. The misfire topic is getting a lot of views, so I assume there's a bunch of other TJ owners whose Jeep 4x4s are aging and need some attention. I agree with Biggman100, joining these forums and posting a question is going to get you help and educate the rest of us."—JJ_Jeep, Forum Member Since June 8, 2013
