cunterbalance shaft

[the oldstuff]

Hi all, I was wondering if anyone here has removed their counterbalance shaft? I have a 70degree V-twin Yammy engine and am unsure if if might rattle my balls off if I removed it. Is it worth it in terms of power gain (rather quicker revving)? Anyone in ChCh do head/flow work for beer and pizza, rooting the missus etc?

Well the early 70degree XV750/920/980/1100 didn't have a balance shaft and they're quite acceptably smooth. They do seem to have an odd balance factor though...the TR1 crank i have here works out at around 34% which is unusual.....
The one TR1 based pre 82 racing locally has had i believe around 2kg taken off the crank....

i've been doing head work for around 40 years now....cash speaks loudly.

So where is "out in the cold"? Close to me or just a euphemism for also being married?
