Hi, just wondering if any KDX200 riders have any tipps on the best ways to get a few more bhp from my 1988 Kawasaki KMX200. This is a street-trail bike, with a 2way KIPS,(no main ex port slide). i think the motor is based on the 86 KX125, (67mmx54.4mm)but very detuned, (30bhp) Im re-building the bike as a supermotard, but as the motor is apart, i want to make some modifications to improve performance, particully top end power, as it goes a bit flat after 8000rpm. Im going to get a performance pipe and silencer as the original one is damaged, im hoping that this will improve power, along with some mild porting work to the cylinder. Im going to use the V-Force reedcage for the KDX200 as its the same size reedblock as mine. Can i run a bit more compression if this is likely to help? Its 8.0;1 std, and i dont mind running 98RON gas. Also the Carb is a tiny VM26mm, and im sure that this is holding back my motor at high rpms. I need to retain an Autolube feed to the inlet rubber though, so should i have the VM bored to a larger size? or will a TM28-32mm carb fit. If i fitted the KDX200 intake, i could use the PWK35, but then i dont know how i could hook up and oil feed to it? Any advice would be great!
