Gasket
Here's another item you might want to replace when you are changing out your front sprocket. Because of it's big back tire, the chain is further away from the center of the engine than most bikes. The engineers at Yamaha decided they had better support the end of the countershaft since it is cantilevered out there so far. They also figured they had better feed some oil out there as well. These Countershaft Seals keep that oil where it belongs, lubricating the countershaft outer support.
Leaking Base Gasket? Replacing your worn Rings? Here are the gaskets you need to put your TW200 top end back together after a tear down. Includes: Head Gasket, Base Gasket, Stud Gasket, Head Side Cover O-Ring, two Valve Cover O-Rings, Base O-Ring, Stud O-Ring, Rocker Shaft O-Ring, two Cam Chain Tensioner O-Rings, Intake Manifold O-Ring, two Valve Stem Seals, and Exhaust Gasket.
This kit of O.E. Suzuki O-rings replaces your leaky, weepy, and brittle O-rings that fit between your DR's oil cooler lines. You get 4 O-rings in this kit to replace both feed and return line O-rings.
If you're noticing oil leaking or creeping around your oil cooler, oil cooler lines, or engine, you may have one or more failed / failing oil cooler line O-rings. Replace them now before they completely fail and you run your motor dry of the precious oil it needs to operate properly.
Here are the O-Rings you need when you perform an oil change. The largest one and the smallest one go inside the oil filter housing cover. The second largest one goes on your oil drain plug. The second smallest one goes on your oil fill plug. Replacing these O-Rings regularly will help keep your engine from seeping oil.

This kit includes one OEM drive plate retaining wire & one OEM inner steel drive plate.
If you've ever changed the clutch on a DR650 you will be familiar with the extra steel plate at the bottom of the stack that is locked in place by a very thin metal wire.
Generally, when you do a clutch replacement on the DR650, you do not need to remove or replace these items. If you do need to (or if you have already) you will come to realize this wire is not very strong and is prone to breaking if not treated with care during the removal / installation process.

Eagle Manufacturing balancer lever kit, featuring top-quality components.
The Eagle Manufacturing idle-shaft lever and spring is designed to replace the less durable stock unit. The one-piece lever is precision machined from 17-4PH hardened stainless steel, ensuring exceptional strength. The kit also includes a stainless doohickey and a torsion spring with a drill bit, replacing the previous extension springs with a superior torsion spring for enhanced durability.
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 Neutral Sending Unit "NSU" on the DR650 can be a problem. The factory screws tend to loosen over time. You really would not want them to get loose in your motor! The permanent solution is to safety wire them. We looked high and low and finally found pre-drilled screws in the correct length and thread pitch. Here we offer a complete kit to take care of those pesky screws.
If you don't do this, you don't have a screw loose, you have TWO screws loose!

Repair Manuals
Clymer motorcycle repair manuals are written specifically for the do-it-yourselfer. Whether it's routine maintenance or more extensive repairs involving engine and transmission disassembly, Clymer repair manuals provide all the information you need about your motorcycle. With step-by-step procedures, detailed photography and extensive use of exploded views, each manual is based on the complete disassembly of the machine. Unlike OEM manuals, which are purposely designed for the professional technician with an impressive array of specialized tools, equipment and knowledge, Clymer manuals are designed for the first-time user.
The DR650 manual features 278 pages of color wiring diagrams, illustrations and photographs. There are 15 chapters, ranging from general information and troubleshooting to brakes, suspension and full color wiring diagrams.
Clutch, Engine & Maintenance
This tool helps ease the pain of accessing the neutral safety switch. This holder is the quickest and easiest tool out there to get a grip on that hard to handle hub.
Laser cut to the exact pattern that EBC makes their clutch plates from, it makes loosening and re-tightening the clutch nut a breeze, and minimizes the likelihood of damaging the clutch hub.
Drivetrain, Engine
Retainer, Gasket
OEM Suzuki seal retainer for the DR650. Simple insurance against your countershaft seal popping out of its bore.
This is not a common problem but for those folks who have had the seal come out it has proven to be quite difficult to get it to stay in place. This steel retainer eliminates any possibility of the seal coming out and ruining your day by coating your rear tire with oil.
Engine, Fuel and Intake
Driven Engine Block-off Plates will stop the annoying and possibly damaging backfires from occurring while allowing you to remove a few pounds in associated valves and hoses from your bike. On late model EFI bikes with O2 sensors, ESPECIALLY when using Dynojet's Power Commander 6 with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your O2 sensor's values and make it impossible to get a correct tune.

Drain Plug
It is a good practice to replace your sealing washer with every oil change. These 10 piece kits are made up of 5 Copper washers and 5 Aluminum washers. The manufacturer recently decided to make half of the kit Copper washers as that is the material of choice for many OEM manufactures. This gives you the opportunity to decide which you prefer, but either will work great at creating a leak-free seal between the case and the drain plug.
