KLR650: Engine

KLR650

The Kawasaki KLR650 is a 651 cc single, liquid-cooled, 4-stroke, DOHC, 4-valves, dual-sport motorcycle intended for both on-road and off-road riding. It was a long-standing model in Kawasaki's lineup, having been introduced in 1987 and remaining almost unchanged through the 2007 model. The 2008 model was the first significant redesign of the KLR650 since its inception.

Your automatic cam chain tensioner is spring loaded. This can make it difficult to install as it wants to extend before you have it bolted into place. This handy tool will back off the cam chain tensioner mechanism and hold it for you. No more awkward 3-handed contortions are required to get the tensioner installed.

Our very own version of the popular thermostat bypass for the KLR. Gives faster warm up and more constant engine temperatures. Eliminates the wildly fluctuating engine temperature gauge. A more controlled and constant temperature is easier on your piston and cylinder and may prevent or reduce oil consumption. We use a 180 degree thermostat instead of the stock (too cold!) 160 degree unit. Warmer coolant temperature promotes better fuel vaporization and can increase fuel economy.

Our bypass system mounts the new thermostat in a small billet extension housing right where the stock thermostat is now. There is no bulky external housing to hang off the motor. The bypass hose tees in to the lower radiator hose using a length of quality high temperature silicone hose. It all makes for a clean simple installation.

The complete Thermo Control package - Our in-house designed Thermostat Bypass kit, a set of Custom Silicone Hoses and a Hi-Pressure Radiator Cap. All combined to help your KLR cooling system be at the top of its game. The Thermostat Bypass kit includes a thermostat with a higher temperature rating that will keep the motor more in its happy spot.

The Silicone hoses are stronger than the stock rubber units and will better resist cracking and leaking.

The Rekluse EXP employs the same EXP assembly as their premier product; the difference is that it fits into your stock clutch assembly, saving you money! Now you can enjoy the benefits of Rekluse auto-clutch technology on your KLR.

An auto-clutch automatically feeds out the engagement of the clutch using centrifugal force. This allows you to start and stop without touching the clutch lever. The automatic feed is fully adjustable to suit the rider's needs while retaining full manual override with the clutch lever. This automatic feed delivers easier on/off throttle transitions, improved traction, better control, and more confidence.

Superior Filtration:

This should be the last oil filter you will ever buy. Made from laser cut, medical grade, 304 stainless steel micronic filter cloth, this filter provides 200% more filter area in many cases. Most good paper filters will pass particles in the 90 to 95 micron range, and some tested, as much as 300 microns. Sand is about 125 microns and a white blood cell approximately 25 microns. Flo's stainless filter catches items down to 35 microns "absolute", which is about 3 times better than most good paper or brass filters. The pleat seam is welded, able to withstand up to 600 degrees in our filter, not glued, like paper filters.

E3 Resistor Spark Plugs

  • Unique electrode shape maximizes the power created by the spark plug – Diamond Fire technology
  • Electrode is a combination of performance and technology that results in an improved flame kernel shape
  • This flame front ignites the bulk air/fuel mixture faster, moves heat into the combustion chamber faster and creates a more localized pressure front for faster pressure rise during the cylinder power stroke
  • The result is more complete combustion and an improvement in engine performance
  • A truly premium performance plug
  • Sold individually, unless otherwise stated.
