    I'd be happy just doing the rings on my 750 SECA... spare change is a little low right now.

    Is your 750 losing compression?
    How many miles are on it?

    You need to take inspiration from Alan Millyard and build an XJ straight-8!
    How are your machining skills?

    Don't remember the numbers offhand but they jumped a good 10 pounds when I added 10cc/cyl oil and puffed it again. Bike has 49,710 miles on the clock and it's taking a quart every few hundred miles, not quite enough to smoke but the huffing from the oil fill plug at idle is significant. Plan at some point is to ring it and do the valves along with a new timing chain, the ultimate goal is hitting 100K miles. I know a tool & die maker with some 70 years of experience who's willing to do the machine work so it's just a matter of gathering up the needed parts & gaskets then dragging the bike to my working area... which is a disaster zone at the moment.
