G'day,
I am in the process of fixing up a 1978 XL250s. I have plans for a larger carb, megacycle cam, high comp piston and to replace what ever other engine components seem a bit old and worn. My question is what kind of exhaust could I fit for optimum performance. It is a single cylinder, but has twin exaust ports the twin headers then go into a single muffler. My original plan was to switch to two single pipes going down and under the bike, but after thinking about it more I have a feeling this will be bad for performance as there will be bugger all back pressure. Does anyone have any suggestions for designing an exhaust that will compliment the other performance upgrades and still look cool.
Regards,
Beau
