not sure if I posted this before but I was reading it again and wishing I could build an engine out of billet:

for those wondering why this was done for a stock bike: 1) the stock h2's gearbox can only take between 30-60 minutes at wide open throttle in 5th gear before it fails, and 2) this makes the h2 a more touring friendly bike instead of screaming death machine.
