    recently bought a mystery VFR750 engine + caRbs from a known HawkGT forum member from Boston area to replace the gen3 engine some dolt tried unsuccessfully to get working in an '87 frame after that guy's original 700 mill done blowed up !

    first concerns were sand-blasted covers and a hand-cut cardboard clutch cover gasket along with some suspicious sounds when turning the crank.

    compression test showed #1=120psi/#2=45/#3=90/#4=100, so i immediately wondered why i hadn't insisted that the seller do a compression test b4 he shipped it. my fault for trusting the seller.

    tried with oil, not much change, so i pulled the head and found 2 very leaky intake valve on #2, maybe bent from bad assembly job after a rebuild ?



    the pistons i saw were surprisingly non-stock, so knew someone had built the engine, probably as a cheater race engine: high-compression, domed pistons with machined valve clearances. different material too. looks like CNC work, could be Cosworth.

    looked more and found the heads had been ported and polished. special high-lift, longer duration cams and matching valve springs. what the hell ?? thought i was buying a stock, running motor, but i'm not too disappointed !! didn't need another engine job, got one apart already .

    HRC cam at right, stock left.

    Looks like a great project on the go. But Sq. It is not a fault to be trusting of people in general. If you knew this guy was a shit, then yes, your fault. Things sometimes just don't end up ideal.

    In a bike and running?

    All sounds VERY INTERESTING. Please give more of the story.

    Am actually quite ENVIOUS of your luck.

    OH, yeah, just resumed work on that project:

    Rick, i might be happy some day to sell you or anyone the whole shebang if you're interested, but first i gotta try to get it running. Absent for 4 months from it.

    Just getting back to days in the shop after a long, miserable winter when i had no transportation. Other ongoing projects need attention too.

    used some tricks to remove 2 valves, found pitted, rusted-looking seats, and lapped-in, and now i've done that for the first time i'd like to have a go at all the valves b4 i put it back together but need to find a cheapeasy valve spring compressor first.

    just got a new '89 VTR 250 in the shop to try to get running, but this big engine is my first priority except for keeping my 34 yo daily rider roadworthy.

    Squirrelman,

    THANK YOU for the courtesy of a reply.

    You said "Rick, i might be happy some day to sell you or anyone the whole shebang if you're interested, but first i gotta try to get it running. Absent for 4 months from it."--DEFINATELY INTERESTED should you decide to let it go to a new home.

    Please keep me in mind.

    Progress reports as they happen as well if you'd be kind enough.

    Kind regards

    Rick

    OK, will do. i have way too many simultaneous projects to work on and can't focus enough time on this engine work.
