Do you need to freshen up your good old Suzuki DR-Z400?
Most likely, you got a fuel overflow issue somewhere or carburation issues.
 
In most cases, replacing all those tiny seals and worn parts on the carb. is needed to get your bike working properly again. It's fairly straightforward and will go a long way to have it run smoothly all the time.
 
The new fuel these days is more aggressive on the rubber parts of the carburetor and needs replacement after a few years.
 
This kit contains all the necessary parts to rebuild one carburetor like new again!
Parts like gaskets, seals, and O-rings, plus specialty parts that may wear out or clog up over time, also include the float needle valve (often overflow issue)
 
This is a great kit and includes many pieces not available for individual sale. Detailed picture included for part identification.
 
Note: It doesn't fit the LTZ400 because the needle valve and diaphragm are different.
 
Before you think of opening your carb, pick up this carb screw replacement set and save yourself the headache for when you strip those damned JIS (Japanese Industry Standard) screws. We've all done it!
