Shane Watts DirtWise Riding Tip: Bike Preparation - Part I

Shane Watts

It is very important to have a well prepped machine BEFORE the start of your next ride because there is nothing worse than having your roost session cut short by a mechanical failure – no one likes being “that guy”!

First off, it’s critical to have the correct tire pressure. With our tire pressure now, generally we like to have between 10 and 14 PSI in normal conditions. In muddy and sandy terrain you will want to try and get a little extra traction by dropping it down to between 8 and 10 PSI. That’s going to be more beneficial by allowing the tire to spread out a little bit, getting a wider tread pattern and hooking up a lot better. Any lower than 8 PSI definitely increases your chances of getting a flat tire which is what we don’t want, plus your tires don’t perform as well at this very low pressure setting because they start “rolling” out from under the rim.

You always want to have a good set of brake pads – not just pads that have a lot of “meat” on them, but pads that also perform well. Some brands out there are atrocious at slowing you down. Sometimes you may needs to bed in a new set of brake pads to form the shape of your existing disc, or you may need to even generate an excessive amount of heat into them before they start working well – A great way to work on your skills improvement and to bed in front brake pads is to perform the “Front brake skid” exercise that we use at our DirtWise Academy of Offroad Riding schools. In very muddy conditions you may even consider using sintered brake pads for increased durability for the gnarly conditions you are going to be faced with.

Be sure to have the correct chain tension on the motorcycle. When the swingarm is horizontal that’s when the chain tension is at its tightest. Initially you will need to either push down on the rear of the bike until the swingarm is horizontal, or remove the rear shock to make this easier to do. Keep adjusting the chain and checking it at the horizontal point until the chain is situated there with a little bit of slack in it. You want that little bit of slack in the chain especially in the mud and sand as the chain will tighten up even more when this muck gets forced in between the chain and sprockets. You definitely run the risk of snapping the chain, or locking the engine up if you’re running your chain too tight. Once you have the correct tension on the chain go ahead and position the bike back on a stand or leaning against something and then make a measurement of the resulting “slack” in the chain at a easily identifiable reference point/mark on the swingarm/front chain guide. Use that knowledge in the future to easily and accurately obtain the correct chain tension for your machine.

      I believe this is a topic which hasnt been explored much on here as I havn't been able to find any info.
      I am curious to know if there is a road legal tyre that isnt knobbly that will fit onto standard 21" and 19" rims on a cr250. 
      I plan on commuting on the bike on road and dont thing I'll be using it much on the dirt any more.
      A few days ago I nearly head on with a T junction because the knobblys didnt hold up while breaking.
      Has anyone on here switched from knobbly to road legal flattrack type tyre on original rims?
      Any pros cons to doing this?
      Sizes, makes, options would be appreciated
      Cheers guys

      Some big names low on the list this weekend at this 3 day WESS race.   and a Yami gets the win.

      Jarvis had some bad luck.

      GNCC®/Hare Scrambles Focused Racer
      All new for 2019, YZ450FX™ is based on Yamaha’s flagship motocross model—the YZ450F—with many added features and unique settings that make the YZ450FX the ultimate GNCC®/Woods racer.
      Yamaha Power Tuner App
      Yamaha’s exclusive Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike via the onboard WiFi system for the ultimate in track-side tuning.
      Electric Starter System
      Utilizing a compact starter motor and ultra-lightweight lithium battery, the YZ450FX maintains the convenience of push-button starting, for effortless restarts under pressure, and relaxed riding when the clock isn’t ticking.
      Potent Fuel-Injected Engine
      A high-compression cylinder head, forged piston, aggressive cam profiles, cylinder geometry and much more work together to give YZ450FX riders the ideal power spread in challenging GNCC® racing conditions.
      Advanced Alloy Frame
      Yamaha’s bilateral beam aluminum frame features main spars, FX-specific engine mounts and an engine mounting position that centralizes mass and provides an ideal balance between cornering feel and straight-line confidence.
      Class-Leading Suspension
      Yamaha uses KYB® spring-type forks on all of our YZ® models, with industry leading function and easy set-up at the track—these fork are ready for the top step of the podium straight out of the box.

      With electric start, an 18‑inch wheel, a wide ratio 6‑speed gear box, the YZ250FX is a powerfully‑built, lightweight machine engineered for cross‑country victory.
      Innovative Hare Scramble/GNCC® Engine Design
      Based on the championship-winning YZ250F™, featuring Yamaha’s revolutionary rearward slanted, liquid-cooled, DOHC 4-stroke power plant with forward-positioned straight downdraft symmetrical intake, and with an added sixth gear and wide ratio transmission, the YZ250FX™ is an “out-of-the-box” Hare Scrambles/GNCC® competition machine.
      High-Spec Engine
      The engine is based on the YZ250F, and includes all the same race-winning features: an updated cylinder head, lightweight forged, two-ring, flat-top piston; a shorter, more durable piston pin with diamond like carbon (DLC) coating; a revised piston oil jet, and advanced connecting rod, crankshaft, and counterbalancer designs. Together, the result is improved peak power, power delivery and overall durability.
      6-Speed Transmission
      A wide-ratio 6-speed transmission is used to insure the right gear is available for the wide variety of terrain found in cross-country racing.
