Hi Mike,
the figures you,ve quoted for the rears is far too softly sprung, as you,ll have 2 people plus the fuel tank & all the running gear I would suggest 250lbs on the rear.
As for the front, most folk with a car engine use between 300 to 350 lb springs so as you.re using the bike engine maybe 250lb on the front too.
cheers
andy
