My wife is totally independant and earns her own money and buys her own suprises. We keep our finances seperate. So that's not an issue. She just doesn't like me buying old clunkers because they're too much work. She would rather I buy new bikes. "Focus on riding, not fixing" Is her advice.
I might never use the parts, but the bike will always be easier to sell as a complete basket case rather than a 90% basket case.
You'll find the parts in the states, just contact one of the links I listed. They made that Rotax motor up until about 98-2000. The last ATK that came out with it was a 2000 model.
