BSR33-P68 Mikuni Carb- OEM Yamaha Rhino 450 2P5-E4901-01-00

Description

This Mikuni BSR33 Carb was specially designed and built for Yamaha and is for replacing carbs on Yamaha’s 2006 thru 2009 450 Rhino models with OEM carb part number 2P5-E4901-01-00.

Throttle cable rotor side cover, oring and screws are included.

Because CV carbs are built, tuned by design to suit a specific engine, we give no grantees that this will work on any other engine and from experience suggest they wont. No returns accepted.

If reading this page because you’re needing a carb to get your ATV or Quad back up and running, our most popular alternative for this size Mikuni CV is the TM33 pumper carb. There is an issue with fitting the TM33 to some brands where there is no available room above your existing carb as it will physically replace this item except for its protruding up and forward throttle cable bracket. Performance wise the TM33 will like all of our pumper carbs, launch your engine into a whole new world of performance over any CV.

To explore other carb options:

To best select an alternative replacement Mikuni Carburetor for your motorcycle please follow the steps listed out below. Due to the requirement of virtually every model bike requiring a unique set of jets, our process below will allow you to correctly select a jet kit and other associated components to your personal requirement. 

On the main menu to the left of the page, hover over the carb listings for the following carb types, TM Flatslide non-pump, maybe also look at VM Round slide and TM Flatslide with accelerator pump and then select from the drop down list the desired Mikuni carburetor size option for that particular carb type.

Click on each carb size and type you believe may suit your engine and remember don’t just look at similar size carbs as to that fitted on your bike as often some bikes that may have come standard with say a 32mm carb may well run with carbs as big as 36mm.
Better venturi design and to a point a larger bore size equates to performance improvement where with Mikuni the progression ranges from the VM then TM and topped off with the TM pumper carbs on 4-stroke engines. Our TMX two stroke carbs work best with none or at worst minimal jetting on any reed valve engine over 125cc.

Do be careful if we don’t have an exact Mikuni carburtor suggestion for you bike, not to up size too much as eventually this will cost you mid-range performance.
When clicking on any individual size Mikuni carb from the drop down list it will put you into a page showing not only the carb itself but also any item relevant to that carb, being jets, flanges, tuner kits, cables , throttles, air-cleaners and a range of carb to OEM air box adapters to also suit. This also makes alternate jet selection easy for you if you have your own spec as only the type jets for that particular carb are shown.
When clicking on the carb itself, thoroughly read the carb description and check for size suitability. Then back arrow back in the carbs main page and go into the tuner kits, which show in the sales drop down list the jetting kits we have for confirmed suitable engines for that particular carb. Again thoroughly read the tuner kit description.
Basically if your engines not listed choose from the choice of others with a similar per cylinder capacity that you believe to be of comparable performance. This will give you a good jetting start point. Keep in mind a 1000cc twin is much the same as a 500cc single.
If you’re comfortable with the dimensions, suitability and an associated tuner kit for a carb, order it or otherwise please call us to further discuss on 0747712677.

Unlike many motorcycle manufacturers’ purpose modified versions (generally modified to comply with emission laws for worldwide sales), these Mikuni factory VM and TM carburetors are both 2 and 4 stroke compatible and are regarded by the Mikuni factory aftermarket racing division to be the best performing version of these carburetors ever made.

Tuner jet kits can be purchased separately for many different motorcycles as per the corresponding  options. These kits consist of the suggested jets for changing that are not matching those factory fitted in the Mikuni TM, they include an extra one size up and one size down main jet for tuning the main circuit due to fuel quality variations, altitude and climate. Testing and conformation of correct main circuit jetting can only be done by physically changing jets and WOT testing.

These tuner jet sets have been determined from thirty years of experience, customer feedback, plus research and development as the Australian Mikuni distributor. From time to time these may not be exactly right for every engine, usually due to changes to porting, compression or numerous other things that contribute to the requirement for additional fine tuning but as a rule our kits are spot on or a very close and useful starting point, but we give no guarantees and sorry do not release kit details or jet size information. If you have your own spec simply purchase the carb and buy any other required jets from the jet pages. This also applies to replacing jets in other Mikuni carbs as the needle jet and others items may not match and fit.

Keep in mind that these are suggested specs, and all tuning procedures, as found in our Tuning Tips section must be adhered to for the confirmation of any supplied jet’s compatibility with your engine.
