Pilot Modification Recommendations by hoser..
Please ask before you start buying parts and paying for modifications just like any other hobbie all the 
parts,vendors, suppliers, info, advice is not going to be to your advantage plenty of snakes in the grass 
just waiting to sell you something you dont need or can get some place else cheaper, that is the
beauty part of the Pilot Odyssey.com Message Board - discuss before you act or buy . 
                                                 
                                                 
     1.Modify your air box so the engine can breath better, just about any modification you do will require
     the more air to the engine. You don't need to add the pre filter unless you ride in extreme dusty conditions
     and are tired of washing filters.
      
     2. Change the stock clutch to something you can adjust, just by allowing the engine to rev 500 RPM more
     on take off will make a night and day difference in the way your Pilot performs. On a stock machine I would
     set the clutch to engage at 3800-4200 RPM.  ATV Racing can set you up with a Power Bloc for about 
     $250.00. Don't be scared to ask this guy questions about clutching.
      
     3. Next would be a after market pipe and silencer to make the engine breath even better, I recommend you
     get the REV pipe NOT the "torque" pipe, dont get hung up on the "torque" name or wording trust me the REV
     pipe makes more "torque" from idle to 7900RPM I have tested both pipes on 2 different Pilots ftom stock to 
     full midified the REV pipe out performs the "torque" pipe in every way espessually for making "torque" 
     ATV Racing and Power Pros offer both rev and torque pipes, Power Pros fabricates the pipes ATVR sells.. 

     4. A larger carburetor, something around 36mm for torque and 39mm for a high revving engine, you can 
     get both from SUDCO  and from Carburetor Parts Warehouse SUDCO is a major supplier that supplies to 
     most all shops and other vendors shop around for the best price who ever you order it from is just going to 
     call SUDCO and have them drop ship the carb to you anyways.

     5. Porting, if your still not satisfied with the amount of power you engine is putting out. ATV Racing and 
     MacDizzy offer porting that will wake up your machine, MacDizzy did mine and I have no complaints, he 
     is also about 200.00 cheaper than ATV Racing, If you decide to get porting done you will need to ship 
     your intake manifold (black rubber part the carb connects to) reed cage, cylinder, head and exhaust
     manifold because all will be modified.  Here you can see some of my porting  Pilot Porting 2003 
Currently my Pilot is running a 440cc ROTAX sled engine that build is here.
