1000/900/800/700 engine weights

[1Mike900]

Does anyone that know the weight of these engines? I was wondering for the best power to weight ratio as they are stock. I would assume that the 1000 would have the most potential, And the 800 would follow second if both were bored to there max? As for the 900/700 they were the mainstay for many yrs, But is there a weight advantage over the lay down vs. upright design besides ctr. of gravity? I would assume the newer design has a better porting layout over the upright?

Thanks
Mike

How about laydown 700 bored to the maximum (1000cc, or is there even bigger one available)?

The biggest bore on 700 or 600 laydown is 800cc but with different cylinders cpc has a 1000cc The biggest bored out cylinder on the M8 is 975cc using stock m1000 pistons and they do this to the old upright 800, 900 as well. I understand that the m8, m7 ,m6 800 and 900 have almost the same crank so I bet the wieghts are close.
