g'day. am currently readying my little girl for use after a long hiatus of stagnation. may as time goes by drop in to pick a brain or two.
she's equipped with a 45 and 48 toother on the rear hub and i'm wondering whether one would be more suitable for the occasional trundle with a painfully low national speed limit of 60/70 mph. meant to be lightning cams and by notes scribbled in the owners manual 8 to 1 slugs at original bore by the "STD" stamp i saw through the plug hole (is there a determining stamp on the crown as to the compression ratio?). bottom end is rapide though no idea of the internals.
it won't be receiving a new chain till it's ready for roadworthying so the 45 is likely to be the one used for any initial test rides. rear wheel is a 19" and by my reading 100 mph would be 4500, and 4800 rpm, which by my calculations is 2700 and 2880 at the 60 mph which i'll be tentatively required to stick to. this is my first big banger v twin having only dads gs1100g suzie and my mz es250/2, dt200 yammie and rg250w suzuki two strokes as reference and a run on a borrowed harley that i thought was an overrated and weight piece of ****.
obviously the 48 would be better in traffic but the plans to use it for mainly highway runs. is the near standard 45 going to be the better for that and user friendly enough round town too as the chain isn't notably worn? or will the cams and comp knock the low speed torque around and make the 48 a better proposition?
thanks for your time, glen.
p.s. will be joining the VOC soon as i'm more suitably prepared now than this time last year. apologies to Vince Farrell and David Hills for the delay.
