2008 KLR-650 Snap Shots

There's nothing quite like a tracking gun shot in an air-to-air engagement. Even in today's
modern aircraft there are certain assumptions that are made when designing a gunsight,
and a tracking shot only comes when you've satisfied those assumptions - closure is
under control, range is valid, sight is stabilized, etc. And as you can imagine, they don't
come easy. More often, a pilot will be presented with shots of opportunity where the most
important assumptions are met, but not all - a snap shot. When this occurs, the pilot relies
on his experience and knowledge of his systems, a little Kentucky Windage, and a little
luck, and puts a burst of gunfire into the expected path of the enemy. A highly trained pilot
will make good use of these opportunities, and in doing so, can sometimes get a kill even
when his adversary is successfully defeating other shot opportunities.

Likewise then, with this page. These are Top Gun snap shots taken on the new KLR.
We've got most of the assumptions satisfied, but not all. We'll give you our best take on
something we see that is interesting and we'll follow up with more detailed information in a
later article. Who knows, we might just get a kill anyway!
  • Rear suspension links are 10mm longer - Kawasaki lowered the bike just like any
    aftermarket lowering kit (rear shock is the same eye-to-eye length as the old one.
    This places the swingarm and wheel higher in it's arc than the older version -
    we've got marks on our Chain Master already just from riding on the street! This
    is also why the chain slack adjustment has gone from 50mm-60mm to 35mm-
    45mm. We'll do more work on wheel clearance, check the chain slack figure, etc.

  • Rear wheel is listed as a 130/80-17 but measures more like a 120/90-17. 120/90-
    17 is a better fit for the stock rim anyway. We will be checking soon, but we're not
    sure there's enough clearance for a 510 knobbie tire.

  • 50.8 miles per gallon on our first fill-up (sticking to the break-in RPM limit of
    4000).

  • (5/18/05) We have roughly 700 miles on the new bike. Although the manual says
    15,000 for the first valve inspection, we decided to check anyway. One valve had
    closed to the limit of the specs already! The others were still in limits but we're
    glad we opened it up and checked. Elden will have a full report on the valve
    adjustment and other observations on a special mid-month Tech Insights (soon!).

  • (5/18/05) Another example of Kawi fit and finish. The left side seat bracket on our
    bike is mis-aligned. So much so that you need to push down very hard on the
    seat to get the holes to match up. There's a metal collar that fits in the plastic of
    the seat. Be careful if yours is mis-matched - ours came with a big bite out of it
    when the factory didn't get the holes lined up for installation.

  • (5/18/05) Elden found out quickly that the metal "curb feeler" pegs that Kawi has
    installed underneath the rider's foot pegs are definitely in the way of an
    aggressive rider. He touched down and caught a boss dot on the highway that
    bent the peg and nearly knocked his foot from the foot peg. Definitely less lean-
    angle clearance with these installed.

  • (5/18/05) The fuel tank appears to be the same as the old one - just with more
    brackets attached. We took the side fairings off for a better look during the valve
    adjustment. One note to home wrenchers, there is more "stuff" to have work
    around on the new bike.

  • (5/20/07) The new chain slipper seems to be an improvement. It is thicker, seems
    to be made of a different material, and has a guide ridge top an bottom. We think
    this will contribute to longer chain life. Speaking of chain life, we carefully
    measured the chain and 35mm of chain slack (factory spec 35mm-45mm) is too
    tight. We recommend '08 owners stay closer to 45mm when adjusting their chain.

  • (5/20/07) The '08 rear wheel appears to be able to move higher into the wheel
    well. We'll know more when we complete our study of the new shock.
    Nevertheless, we did notice that the chain engages the Chain Master
    considerably earlier than the wheel reaching full travel. Although there have
    been some changes to the rear suspension, there has been no change to the
    positioning of the airbox. Our Chain Master already has a nice set of marks on it
    from engaging the drive train. We are going to modify the Chain Master slightly
    for the 2008 KLR. Look for '08 model Chain Masters soon!

  • (5/20/07) There was much made in the press releases about the new fork size,
    and following that, some discussion of using the new forks in the old triple
    clamps. First, we're not convinced yet that the new forks are necessarily better.
    Second, the triple clamps aren't going to cross-over. It will take some work if that
    is a project you are interested in.

  • (5/20/07) The new cooling system is noticeably more efficient than the older
    model. We will do a more detailed comparison in the near future. However, the
    radiator itself is attached to the frame in only two places (instead of three places
    on the old model. With the fairing off, the radiator wiggles around enough to
    make you feel uneasy about it's chances in a fall. As you can see, it attaches to
    the fairing in several places, which does provide some stability during normal
    riding. We hope none of you get to test it's crash worthiness any time soon.
This is the longest spacer we've
seen in a fork.
Top shock is the new 2008
piston/shim stack.
An efficient new radiator, but Kawi
really left it hanging in the breeze.
We wish it had more solid support.
  • (7/2/07) We had the weight of the rear spring checked by Mark Behnke of
    Precision Concepts in El Cajon. The new spring is 4.91kg (275lbs), compared to
    5.05kg's on the old model. We will have two new springs to cover both old and
    new models in the next 4-6 weeks, and will allow us to accommodate a much
    larger range of riders.

  • (7/2/07) We've had questions ourselves about the fan switch on the 2008 since
    the darn thing hardly seems to ever turn on. We finally got our hands on our
    service manual: 2008 fan switch turns on with rising temperature at 203-214 deg
    F (201-212 for the older models) and turns off with falling temperature at 189
    deg F or less (196 on the older models).

  • (7/8/07) We wondered why Kawasaki no longer included the balancer chain
    tension adjustment in the Owner's Manual, even though the same adjustment
    system was present. Turns out the factory DOES include it in the service manual;
    every 7,500 miles.  

  • (7/18/07) Perusing the service manual I did find an interesting change in the
    procedure for installing the rotor. We don't see the need to change the balancer
    lever, though we can't see any way around having to install a shorter adjustment
    spring sometime in the future. The new procedure calls for torquing the rotor bolt
    to 15 ft-lbs, removing the rotor bolt, cleaning and drying the bolt before
    reinstalling, then torquing the rotor bolt to 144 ft-lbs.
New 2008 exhaust pipe mounted
to 2005 KLR650.
  • (7/18/07) Here's a picture of one-half
    of the 2008's new "one piece exhaust"
    (as claimed in Kawi's literature) fitting
    nicely on a pre-2008 with stock
    muffler. Not sure where the "one
    piece" bit comes from. The new pipe
    sports a better mounting system for
    the pipe cover, with more space
    between pipe and cover and rubber
    dampers. Hopefully this will solve a
    common problem with the pre-2008
    models which would often exhibit
    cracking around the mounting holes in
    the pipe cover. The rubber dampers
    might bear watching to see how they
    hold up to the heat around the pipe.
  • (6/10/07) Here (below) are a couple of
    pictures showing some interesting
    finds concerning the 2008's
    suspension. We will have a more
    comprehensive article concerning the
    front and rear suspension very soon.
    The picture on the left shows a
    comparison between the new shock
    and the old model. The new shock
    uses a conventional piston and shim
    stack, a definite upgrade for the 2008.
    The picture on the right shows the
    surprisingly long spacer found in the
    fork. This thing measures almost 12"
    long! Again, we'll have a more
    comprehensive article on the front
  • (6/10/07) Speaking of forks, we asked a practicing mechanical engineer to do
    some calculations for us based on our measurements of the new forks. The new
    forks have a larger outer diameter but thinner walls. Structurally, the new forks
    should be able to resist deflection 12% better than the old forks. Of course, there
    are some other variables that come into play in the real world of riding. One note
    we'd like to mention. In over 255,000 miles of KLR riding, we've never had a
    problem  with the old KLR forks. We've never used a fork brace either; just
    proper axle spacing, proper torque and fastener tightening sequence, and
    properly adjusted steering bearings.
    and rear suspension very soon, and we're currently working on ways to
    potentially upgrade both ends.
  • (8/5/07) We ran an informal braking test from 50mph to zero between the 2008
    and a pre-08 with the 320mm EBC rotor (front brake only). Both bikes stopped
    virtually in the same distance. This speaks well for the new 08's front brake, but
    also shows that owners of pre-08 models can have the same performance by
    upgrading to a larger rotor.

  • (9/2/08) A few months back, we had a strange problem with our KLR that we
    initially attributed to the carb. The bike would only start and run with the choke
    lever pulled. The bike would inevitably die once the lever was closed. Our big
    surprise was finding the emissions canister had fuel in it! Emptying it solved the
    problem, but now we had a new mystery - how did it get there? We are carefully
    about not overfilling our CA tank, and the bike had never been tipped over. Fast
    forward to this month when we were doing some maintenance, and had removed
    the emissions gear. We pulled out the service manual to confirm the hose routing
    as we were reinstalling the equipment and to our surprise, the hoses had NOT
    BEEN CONNECTED PROPERLY at the factory! Probably goes a long way to
    solving that fuel-in-the-canister mystery... Check your emission hose routing!
UPDATE!!
The Top Gun
Chain Master
will fit 87-08
KLR650s.
