Hello all,
I am new to the forum and have just bought an07 Brute Force 650i. I am riding at about 3500 ft and I need help deciding what to buy to increase the engine performance. I need to know what combinations of filter, jetting, cdi, and exhaust would best suit this quad, or what has worked well for anybody else in the past. Please be specific with brand names as well. An increase in bottom, and mid-range power is what I am looking for the most. Thank you in advance for concidering my request.

 

I would try the K&N filters for that air, oil and Pre-charger, part numbers KA-7504, KN-204, and KA-7504-PK, available at the Yamaha dealer in Chilliwack, and Maple Ridge Motorsports, or Mission Motorsports, 3-D motorsports in Abbotsford, Motorcycle world or Daytona Motorcycle in Surrey
