Roight then,
yas1 (125cc twin yamaha) 7.5cm from crankcase center to outer of sprocket
nsr80 and rg80 8.5 cm
rxs100 and xt350 9cm
rgv125 10cm
rs125 (rotax) 10cm but the chain is on the wrong side with that.
think the xt350 was about 36cm long but neither of them had barrels/heads so no idea how tall they were.
Thinking about it i don't think a 3.5" offset engine will be all that bad for the handling, are you measuring from the crankcase center or the whole engine?
