The magazine's Honda XR650R performs remote field work as an HD video filming platform. Reliability is essential. After purchasing the bike in non-running condition, I ran a compression test when the engine refused to start. I moved from the simple compression test to a full-fledged cylinder leak down test, the pinpoint diagnostic tool of choice. Want to know more about a leak down test? Click here for the 4WD Mechanix HD Video Network feature and details on the leak down test!
High cylinder leakage called for a top end inspection and repairs. That tear down for inspection can be found at the magazine as the HD video how-to: http://www.4wdmechanix.com/Honda-XR650R-Motorcycle-Upper-Engine-Rebuild-Part-1-Tear-Down-How-to.html.
At left is the cylinder leak down test covered in the HD video how-to. At right is the actual top engine tear down, part of the current rebuild. See both HD videos at the magazine for details!
The step-by-step teardown, rebuild and assembly are now a single HD video streaming rental at Vimeo On Demand. Included in this rental is a bonus feature on valve adjustment (which is also available as a separate streaming rental). You will find this 54-minute feature at: http://www.vimeo.com...and/hondaxr650r.
Here is a review of that rental video:
"Coming across this video couldn't have been more fortuitous - both in timing and content. I happened to inherit a motorcycle of the exact same type and with the exact same problems as the one starring in the clip. The author/producer treats the subject thoroughly and with close-ups giving great detail of the matter at hand. Not only that, he has an online magazine with a forum through which he is eminently available for input and feedback. Having watched this gave me the confidence to embark on the solution on my own - saving loads of money and learning in the process."—David E.
