Always a good idea to put in a new set of Oil Change O-Rings at the first sign of any leakage. This package gives you the three most important: oil filter cap and the one behind the filter as well as the one on the filler cap. All are new OEM Suzuki O-Rings.

High quality aftermarket paper gasket.

The Dirt Racer Complete Clutch Rebuild Kit is the ultimate package for your Yamaha, here's why:

'Stack Height' is the all important factor when renewing a clutch and riders are always best to buy a complete kit instead of separate single plates as sold by manufacturers. Replacing just the worn plate (or plates) may not even get close to rebuilding your clutch to its original stack height and all you get is clutch slip and the job has to be done again.

• Complete set of stack height controlled anti-swell friction plates
• The friction plates are forged allow with wide "Ear" construction to spread the load in the clutch basket and prevent "Dogging" (when the ears cut into the allow clutch basket) which causes a rough clutch, promotes slippage plus it ruins an expensive part of your engine
• EBC unique alloy article impregnated clutch facings that wear longer and resist burning
• 15% stronger heavy duty, shot peened clutch springs to clamp those plates together firm and strong for the life of your clutch

ProCycle 440cc BIG BORE 89mm KIT 1 With Cam. Complete kit with 12.5:1 Wiseco piston (with rings, pin & clips), big bore cylinder sleeve, HotCams stage 3 camshaft and top end gasket set. You will have to have the larger sleeve installed in your cylinder.

This is one of the few plastic parts on the DR650 that can ruin your day if it breaks or fails on you. This gear helps drive the oil pump to circulate oil throughout your entire motor, without it, your motor will fail entirely. The idler gear is not known for being a common failure point in the DR650 motor but, it has failed riders in the past. Usually in the form of a broken gear or stripped teeth. Upon inspection, look for any kind of crack, chipped or missing teeth on the gear. It is not a complicated repair to swap an old gear for a new one, as the best time to replace it is when you've opened up the clutch side case cover for another repair i.e., (NSU screws or clutch hub bushing replacements). This is an O.E. Suzuki part.

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.

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.

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.

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 02 sensors, ESPECIALLY when using Dynojet's Power Commander V with the Autotune feature, the air injection system MUST be blocked as it will introduce additional oxygen into the system which will skew your 02 sensor's values and make it impossible to get a correct tune.
