Installed a Honda valkerie 1500cc engine in my Hi Jet looking for heaver coil springs to take the extra weight look at 250lb coils but are just for a 4x4 to short. hope someone can help me.
Sorry i can't be much help on your spring question, but i (and probably many others here) would really enjoy seeing some photos of your engine swap. How did you go about mating up the Honda engine? Is it more "separable" from its transmission than a typical motorcycle engine? If so, gguess you must have kept the Honda's flywheel and pressure plate-- maybe hybridized it with the HiJets clutch plate? Must see photos!
