You guys sound like you know your stuff re carbs etc, looking for advice.
I have replaced the stock filter on my '83 CVH (XR3 n/a) with a nice Pipercross. Sounds good and much improved throttle response, but the car runs out of breath past 80 in top, and struggles to gain further speed. Can I cure this with adjustment or is it a gearing problem?
Moving to 185/55/15 tyres gives more pull with the power you have, esentially getting more effective Torque to the road. Alternatively you need more power to increase top speed.
