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 want to get a cheaper used FMF exhaust for my bike. The one on eBay I was looking at had some dents in it. Do dents in the muffler have a big impact on the performance? Also the pipe looks to be turned the wrong way does that rotate? I don't want to buy this if the pipe will not rotate because I think it looks like its turned the wrong way and wouldn't fit.

      Hey guys, 
      I am really needing some good advice here from anybody who has ever owned or rebuilt classic Yamaha 2 strokes (1989 - 1994). I live in South Africa, and bought a little farm thumper while on holiday this past weekend. It was advertised as a DT175 which is a bike that is easy to get parts for down here. It has been cosmetically customized and looks pretty darn cool... and lets face it, all the old classic Yamaha 2T engines look the same at a glance! So I genuinely thought it was a naked DT. The bike had no papers, and was used purely for the farmer to putt around on his farm.
      The only things needing attention was the stator cover which had snapped in half - this was visibly noticeable, and a little leak from a badly resealed gasket (both generally easy and cheap to fix here). The bike was still running and idling fine, started first kick, and I had a little ride around the farm before loading the bike up onto my pickup and heading off, thinking I could fix this thing up nicely in no time for next to nothing, and have what we call down in SA "a nuwe speelgoed" (A new plaything) for the weekends when I am not riding my beloved and reliable DRZ400SM. 
      SO, I get home and decide to contact our local Yamaha branch, out of interest, to find out the history of the bike before I start fiddling (Don't ask me why I did not do this all before I bought the bike - It was a spur of the moment purchase, and was sold to me for dirt cheap!). I send off the VIN and engine number. Comes back, and this little freakin' turd turns out to be a 1989 TDR180!! WHAT. But now I am stuck as we do not really have TDR's down here - and I have never even seen one myself.
      Long story short - What alternative could I use as a stator cover? Do any other old Yamaha 2T model stator covers fit the TDR or share similar engine parts? Ordering from Ebay is so expensive thanks to my country being in junk status due to a junk president. So the shipping costs more than the actual item does, and our customs is a joke too. Yamaha has also advised me that this stator cover has been discontinued.
      I have put up local ads looking for parts, contacted FB 2T groups, and local shops. Nothing for TDR's has come back yet.
      Any advice or sharing of experience is welcome!

      Hitting your landing target is critical in motocross. It is also better for your health! Not only hitting your landing, but getting there quickly is also important. The two most common techniques regarding jumping are absorbing the take off to stay low and launching the take off to clear an obstacle, to make it to the landing.

      Since the 2017 series is over I figured I'd share my experience/time racing the series... some entertainment for those who aren't riding as much anymore this time of the year.  This is my first time racing a series and pretty much racing in general.  I entered the Open B class on board my KTM 300 XC and was able to compete in 8 out of the 9 rounds held.  I do include more footage of each event at the end of some vlogs... so if you were there watching or racing, you are probably caught on camera.  Enjoy!
