In fact I just purchased a 2008 KLR and the old Xl will out torque it out accelarate it and is just a lot more fun to ride and fun is what it's all about.
Does anyone have a dyno graph on the old Xl,s I would like to compare it to a KLR?
Here is dyno graph for my -84 XL600r (DP03)
- Engine rebuild, new bearings, 101mm piston from wiseco
- Laser Produro muffler (offroad model).
- Stock head/valves/cam.
- Airbox modified.
Things i change after this run...
- Too small jets in both carbs, later install bigger jets -> better high end.
- Faulty ignition -> new ignition system -> better over all.
And offroad tires loose some hp in dyno...
