                                        Pro ATV Racer, Jarrod McClure, & his 
                                        2009 Yamaha YFZ450 ATV | 
                          
                                Kaska, PA (10/31/2009)- For the 
                                2009 GNCC racing series I decided I would be racing 
                                a Yamaha YFZ 450 ATV. I chose to race the older 
                                YFZ, not the new YFZ450R, because there is already 
                                a ton of aftermarket parts available, and also 
                                since it has been proven at all types of racing 
                                over the past few years. I would like to give 
                                you some insight on what I did to make my YFZ450 
                                race ready. 
                                
I picked up my first Yamaha YFZ450 through 
                                  Blockers Enterprises, a local dealer near me. 
                                  I took the quad right to Bowers Motorcycle Supplies 
                                  where we tore it down to the frame and engine. 
                                  Next I made a phone call to the guys at Yamaha 
                                  GYT-R and had them send me some parts. I picked 
                                  up their whole clutch assembly, also their kicker 
                                  kit, and jet kit.

                                        picked up his Yamaha YFZ450 through Blockers 
                                        Enterprise, then took it right to Bowers 
                                        Motorcycle Supplies where he tore it down 
                                        to the frame to rebuild it from the frame 
                                        up with aftermarket components | 
                                
                                
                                   
                                    |  | 
                                   
                                    | Motoworks 
                                        full exhaust system adds plenty of extra 
                                        power over the stock exhaust even without 
                                        any engine mods | 
                                
                                The clutch assembly is completely different 
                                  then stock, it has more oil passages, is lighter 
                                  and increases clutch life, and I figured the 
                                  kicker was a good idea in case of any battery 
                                  issues. I also installed Motoworks full exhaust 
                                  system and the GYT-R jet kit.
                                
That is all I do to the engine, I like running 
                                  a nearly stock engine for the improved reliability, 
                                  plus it still has plenty of power, and starts 
                                  right up. Now it was time to get some suspension 
                                  components. I began working with ARS-FX this 
                                  year for all of my suspension needs.

                                        likes running a nearly stock engine in 
                                        his Yamaha YFZ450 for improved reliability, 
                                        plus he adds, "that it still has 
                                        plenty of power and starts right up", 
                                        but you can't beat the reliability & 
                                        performance of a GYTR Clutch System, which 
                                        is a must for any serious YFZ450 racer
