Hi Guy's
I think it's great that there is more choice of OB powerheads now - but
at that price you could by a new K&B Pro 7.5 with the leg included and no need to go and buy a tuned pipe just to run it.
Have seen this sort of problem before where the smaller capacity classes become so expensive for good gear that people just move on up to larger sizes.
That's half the reason Gas is getting/gotten so big.
Other observation is I'm always amused why italian motors are so expensive? they have a huge share of the market (lots made and sold), the italian currency is hardly the strongest one around. I thought th Oz dollar was weak but compared to lira. Often wondered what drives the price - maybe I'm cynical but I think the manufacturers, hobby inductry will charge as much as they think they can get away with.
Sorry for the politicing, just my observations.
