  1. The magazine recently purchased a 2000 Honda XR650R motorcycle with less than 1000 original miles on the bike. An honest and forthright previous owner could not start the engine, and given the mileage, we agreed that the problem was stale winter (ethanol) fuel—which had eaten up the plastic tank screen! I trailered the cycle home and looked forward to restoring the fuel system and completing the dual-sport conversion process. The motorcycle will be an HD video shooting platform for remote backcountry documentary filming and off-pavement event coverage, so the XR650R's low mileage seemed a huge
  2. I've written six 4x4 Jeep® and truck books plus a Harley-Davidson book. Most know me as a 4WD Jeep, light 4x4 truck and automotive guy, some as a Harley-Davidson author, and few are aware that motorcycling has played a role in my life. My earliest on-highway vehicle operators license, at age 14, was a Nevada Scooter License. Unique to that era, without the sanctions of insurance and high registration fees, scooters were a recognized means for getting to high school. Nevada was the fifth largest state in the U.S.—with the smallest population at the time... I rode a Cushman on the highw
  3. Many of today's dirt motorcycles have electric starting, and this is a very good idea for the contemporary ultra-high compression four-stroke singles! For these operators, unless the starter fails to work, manual kicking has become a thing of the past... Despite this trend, there are still many kick-start Honda four-stroke motorcycle engines that have an "auto-decompressor" start mechanism. This device, typically mounted at one end of the overhead camshaft, unseats an exhaust valves during crankshaft rotation. The aim is to relieve compression as the piston approaches TDC (top dead cente
  4. Given the opportunity to test the Pulstar® PlasmaCore spark plugs, we targeted the magazine's Honda XR350R and XR650R motorcycles. The XR350R is air cooled, the XR650R has liquid cooling. Both cycles use fixed jet, slide type carburetors. The XR350R has twin Keihin carburetors, the XR650R uses a single, large Keihin carburetor. We rode the bikes extensively. The XR350R is OHV permitted for dirt only use, and that testing took place in high desert and mountainous terrain, both dirt roads and single track. The XR650R with its dual-sport conversion received a full test at both dirt and a
  5. When I pondered buying a Honda XR650R motorcycle, my BRP research spanned the web. Repeatedly, I unearthed references and horror stories about how tough it is to start these engines. Forums were rife with starting and kicking rituals, choking methods and decompression lever habits. Add the mention of stock and aftermarket carburetors, suggestions on how to use the manual decompressor, descriptions of how best to use auto-decompression, you name it. Eventually, one could get leery of approaching one of these critters or maybe buy a newer electric start KTM EXC. Common sense prevailed, after a
  6. In the 1990s, we began riding Honda XR dirt motorcycles. In the early '90s a modest $75 worth of parts invested in a Honda XR75 became youngest son Jacob's first motorcycle at age 12. Oregon friend Kirk donated two core bikes to the cause from his stockpile of old Hondas. When we returned to the high desert country at northern Nevada in 1994, my logical companion for Jacob's XR75 was a used 1983 Honda XR200R purchased from the Reno dealership. Jacob soon outgrew the XR75, and I outgrew the XR200R thumper. Jacob inherited the XR200R when I found the right four-stroke bike, a very well
  7. Hi, Moses! I fell across this website recently while researching some pieces of aftermarket hardware that are on the 2002 plated BRP I purchased here in Bend, OR recently. Saw the bike on Craigslist and thought it looked like fun on the road! I also have a 2001 BRP that I purchased in 2002 which has been lovingly flogged for 12 years now. Reading your blog and many others, It appears the XR650R is a cult classic...Guess I was not aware how good of a bike I had! I too am a graduate from the Univ. of Oregon, 1985. In 1983 I bought a new XR500R for commuting Eugene to home in Florence on the w
  8. Well, I rode the Honda XR650R motorcycle this morning, not unusual in itself, as I've been trying to rack up miles on the top-end engine rebuild in time for Fall riding. One thing was unusual, though. At 204 miles since the rebuild that included L.A. Sleeve machine work, the bike has reached a whole new performance level! The magazine's Honda XR650R top-engine teardown and inspection. My morning riding venue is typically rural highways, both two-way traffic two lanes and divided highway four-lane. I've been on dirt with the Michelin T63 tire tests and have much more planned, thi
  9. So, I have this Euro model XR650R project, and I acquired the bike right. As the upper engine rebuild and other restorative measures unfold, I'm starting to wonder what is a reasonable amount to invest here? The engine work and all the other parts I've bought are pushing things pretty close to $2k - and this bike can't be worth much more than that! Furthermore, I dropped nearly as much on new gear (helmet, boots, gloves, etc...) DON'T TELL MY WIFE! Cheers, David
  10. The Hot Cams Stage 1 cam for our Honda XR650R motorcycles sounds to be exactly what I'm after in power. In the past more power equaled more fun. That still holds true today, but to a lesser extent for me. I definitely will have to put in the Stage 1 cam if the bike shows wear in the top end anything near what yours had. It's good to know there is still more good power to be had even if I don't really need it. As far as that auto-decompressor, I only use it because that is all there is on my xr500r. It is a real pain trying to use to bump start the 500 even when it is on top of a good hill.
  11. At the forums Garage Photo Gallery, member "FullChoke" (Greg) responded to my photo of the magazine's 1984 Honda XR350R motorcycle. We have identical '84 XR350R motorcycles. Greg's cycle has engine heat-up problems, and this raises the issue of how to keep any air-cooled dirt or dual-sport motorcycle engine running cool enough. I'll begin with sharing our exchange at the Garage (below), followed by pointers on how to keep an air-cooled dirt or dual-sport engine from overheating. ************************************************** My comments at the Garage Photo Gallery: Moses L
  12. Building a motorcycle engine for reliable performance begins with careful assembly work. The Honda XR650R project came under the close scrutiny of an HD video camera, and the result is the 49:37-minute streaming video rental at Vimeo On Demand. Following the build, proper break-in of the engine is crucial. During assembly of the XR650R top-engine, care was taken to lubricate critical parts for the initial engine startup. This included lube on the piston pin, rings, valve stems, camshaft, valve tips and timing chain—as illustrated and detailed in the video. Lubeguard Assembly Lube, Perm
  13. The magazine's Honda XR650R motorcycle came to life this week! After months of sublet machine work, parts delays and time management challenges, the HD video series on rebuilding the engine top end has now finished. The camshaft choice, Hot Cams' Stage 1 type, and sublet machine work to L.A. Sleeve Company was followed by my "blueprint" assembly job and precision tune-up to match the engine changes. Learn more about the uncorking and Honda "Power Up Kit" guidelines, plus the ways to compensate for our 4,400-foot base altitude. How did this turn out?...Well, judge for yourselves fello
  14. I pulled the oil filter and passed a large magnet over it but I did not pick up any ferrous metal. The close up photo of the filter reveals many small chips of aluminum. Well all I have to do is open up the motor and start looking for a bright shiny spot! This is the filter out of the 2006 salvage bike.
  15. Demand for more off-pavement motorcycle coverage has led to the launch of 'The Off-Road Motorcycle Channel' at the 4WD Mechanix Magazine's HD Video Network! The new channel covers dirt, off-road and dual-sport motorcycles, including tech how-to, step-by-step tuning and repairs, troubleshooting, backcountry riding and survival tips—everything related to off-road and dual purpose/dual-sport motorcycling! Inspired by the needs of the magazine's 2000 Honda XR650R motorcycle, the channel launched with HD video tech how-to coverage in Vimeo Pro 1080P full-screen detail. Whether you own an iconi
  16. My recent comments on dual-sport motorcycles became the prelude to our latest acquisition: a Honda XR650R motorcycle for the 4WD Mechanix Magazine vehicle fleet! There's a long history behind my relationship to off-road motorcycling, which began when I acquired my first purpose built desert motorcycle in 1971, a 1969 BSA B44 Victor. In the mid-'eighties, my editor at Argus' OFF-ROAD Magazine was Rick Sieman, better known in motorcycle circles as Super Hunky. His legendary roles as both the Senior Editor at Dirt Bike and AMA Veteran Class Plate #1 were Rick's other credentials. When Rick en
