Yamaha uses this seal material in many places on several motorcycles. It is like weatherstripping and is used to seal up the edges in the TW200 air-box. It seals up the air-box so that water and grime can't enter the air-box from the side. Ensures that air entering the box comes from up under the seat.
Are you a fan of K&N air filters? Here's one built just for the TW200. Top of line filtering to keep that engine healthy for years to come.
Here's a UNI dual layer foam air filter element to fit our TW200s. Needs to be treated with air filter oil like any other foam filter.

Dual stage foam: 2 different pore sizes create more trapping area for even the smallest dust particles. Flame laminated foam: Both "Stages" are not glued but heat sealed to provide maximum air flow. Light color foam makes it easier to see where the filter oil has covered and where it has not.

This is the more economical alternative to eliminating the 990 Adventure airbox. Better breathing equals more power. The ITG filter kit makes air filter service a snap. It also simplifies other engine and intake maintenance chores. Our kit features a steel base plate which will not deform like plastic and does not conduct heat as much as aluminum. The white powder coating also helps reflect engine heat. To take advantage of the increased airflow, we recommend upgrading your fuel injection map with TuneEcu or a Power Commander.
Unsurpassed in airflow, dirt stopping and overall performance. Adding a pre-filter to your intake system gives you extra protection from damaging contaminants.

Is the cylinder head intake boot on your DR650 cracked or weathered, is it missing parts of the lip to seal around the carburetor, have you recently pulled the intake boot off only to realize the O-ring behind it is hard & brittle? This kit is your solution to solving some of those mystery problems and make your bike like new again. There can be a great deal of heat that can radiate behind the cylinder head on a DR650 as it is an air cooled engine. With that comes long term maintenance items that will need to be replaced due to them being made of materials that cannot withstand those constant heat cycles indefinitely.
Our kit includes O.E. parts from Suzuki to include:
This seal helps keep debris and water out of your DR650 air box and it may become damaged or missing over the years. It is an important part of your DR650's intake system to maintain & prolong air filter life.
Simply, remove the air box door, then remove the old seal and clean out the track it sat in. Set the new seal in place and cut off any excess material remaining. Install the air box door and you are done.

Extra dirt protection for your K&N filter. Our custom made oiled-foam filter sleeve wraps snugly around the K&N filter to give a first layer of protection against dust and dirt. Oil it like you would any other foam filter.
Wraps around your K&N filter to keep water and small particles out of the filter itself. K&N DryChargers are manufactured from a durable polyester material and are pre-treated with a proprietary hydrophobic process designed to prevent splashes of water or mud from saturating your K&N air filter. The DryCharger will also stop small dirt particles; yet add little restriction to the airflow of the filter. The DryCharger can be installed under the Foam Wrap.
Pre-filter only, K&N air filter sold separate.
Allows your bike to breathe much better giving you better response and performance.
Two layers of foam, catch and retain nearly any contamination you will encounter.
The adhesive that holds the two materials together withstands repeated cleanings even with harsh solvents or gasoline.
These filters are slightly smaller than stock to increase air space around the filter, improving circulation and air flow. A thick, flat breathable foam gasket forms a grease free sealing ring that ensures maximum contact with your airbox.
This kit includes 2 fire resistant pre-oiled air filters and 2 plastic filter frames.

The screws and nuts that hold the Air-box Cover on have a habit of jumping out of the air-box and running away. No idea where they go, but it is far! These cannot be purchased separately from Suzuki but we found some that are perfect replacements. This little kit includes four screws and the square nuts that go into the air-box. We recommend that you put a dab of silicone or something to hold the nuts in so they don't jump ship like the other ones did.
FunnelWeb ProLine Filter Highlights:
Like all FunnelWeb filters, the ProLine Filter features profile cut, single layer, single density foam that doubles the external surface area of the filter without increasing the original filter size.

The single layer, single density polyurethane foam has the added advantage of being easy to clean and the ability to maintain its original shape after numerous washes. Overall, compared with conventional foam filters, FunnelWeb offers more protection from dirt ingestion, has longer service intervals and maintains high airflow rates when dirty.

This is a complete high-performance intake kit for the DR650 that includes our famous TM40 carburetor kit and a K&N air filter with ProCycle wrap.

CNC machined from billet aluminum and anodized black or blue. If you want to retain your handlebar mounted choke this may be the solution.
These no longer fit the new version of the ProCycle Remote Choke Cable. Will not work with the long or short reach choke knobs.

These Mikuni carburetors are correctly sized and easily fitted to your Honda XR600 and XR650L stock motor mounting flange after removing the locator tags and also match the air box when using the silver anodized air-box adapter. This adapter is fitted prior to delivery when purchasing complete kits. For this Mikuni carburetor to operate correctly the motorcycles air box must be opened up to allow more air flow in. Using a hole saw, a 45mm diameter hole will be sufficient for a Suzuki DR650 but some Honda’s require way more. The best process is to keep opening up the air-box until no more improvement is noticed and you will be surprised at the difference. The kit also comes with throttle cables and a 1/4 turn quick action throttle which must be lubed before fitment. The carb comes with a couple of Honda specific adjustments made and pre jetted for your engine. A specially made size 30 pump nozzle is fitted as the accelerator pump circuit on TM42 carbs will not work properly on Honda’s or Kawasaki’s without it.
Climate, altitude and fuel density from different octane fuels all have varying effects on final fine tuning as does cam, exhaust and cylinder head porting etc. For this reason, we have included what we have found to be a range of jets to allow you to tune to most variables.
This carb fits with most aftermarket large capacity tanks. Some larger capacity tanks do not allow the fitment of this carb without modification. A competent person can easily heat and depress the contact area around the throttle mechanism allowing for clearance on problem tanks. Polyethylene tanks start their life as lump of poly that when melted evenly spreads itself around a rotating mold, to later carefully heat with a heat gun any section of a tank and change the shape has no effect on the integrity of the poly itself unless pushed too far, thinning it. We recommend having this professionally done for the reason some people may neglect to properly remove all the fuel from an existing tank or if not competent may make a mess of it.
Quality air cutoff valve replacement kit contains parts necessary for a complete rebuild.

Included in this kit are the parts needed to repair a second generation TK carburetor. You get a new float bowl gasket, needle valve with O-ring, needle, mixture screw, and stock jets for the '01-'21 models kits.
Here is the O-Ring that fits in the carburetor manifold. This is the manifold that holds the carb up to the cylinder head. The O-Ring mounts between this manifold and the cylinder head. When this O-Ring fails it allows air into your cylinder and makes your Air Fuel ratio too lean which causes the engine to run too hot.
This is a new Diaphragm Set for your 1987-2000 TK carburetor. If yours has cracked or ripped, here is a replacement.
