I made my 250 go faster, so meh! A' course, it guzzled fuel like crazy afterwards...Actually, I think you'll find it's the increased mass of the exhaust gas that makes the exhaust gas too heavy for those little engines to move out of the pipes at 'normal' revolutions. Hence the spot where the scavenge kicks in has moved further up the rev-range, and possibly to a useless spot beyond peak power with standard cams and fuelling. An exhaust shop worth a few dollars should probably inform boy racer that 3" all the way from the manifold (Or extractor of they have spent the dosh) to the tip of the pipe is silly, and would sir like a 2" pipe running the length of the car plus a dinner plate at the end of the pipe for vanity?Think boi racers with 1.6litre non-turbo cars and 3" exhaust systems losing around 20% of their power to no back pressure.......but it looks cool
Not true, the engine could have designed in dead spots. Take my RVF400 for example, it's got a horrible bloody hole till about 7000rpm that is easily fixed, and tapers off at about 12,000rpm where it should not. Put in an HRC CDI and you fix get a bit more oomph at the top. The HRC CDI made a difference, I stopped hitting the limiter all the time once I fitted it. Also said vehicle is electronically limited to 180km/h, and this restriction can also be removed.Even if you could get a few mods for the motor, its not going to give more than an extra couple of horses. Which odds are you'll be unlikely to feel, as it will inevitably lead to a loss in bottom end torque.
Concentrate on riding better and getting the most from the bike.That I can't disagree with.Learning to ride the wheels off an underpowered bike will give you skills you will use all your life.
