    Pro 785 - TBone

    Can't wait to get into this bad boy
    Here's the starting point:






    I made a new console plate for it:

    Here's a video with the head off spinning the crank by hand. Do the crank bearings sound a little loud to you guys? Or am I being paranoid? It actually feels nice and tight and it appears as though it has had a recent top end refresh.

    She's got a few nice upgrades to her.

    That MAG is a Wiseco piston. Hard to see in the video if the other 2 match?

    I'd be wondering what the piston clearance was set at.

    Wonder if any porting was done?

    What do you mean crank is nice and tight?

    I don't really think you can assess crank bearings in the engine. Unless they are so bad it makes the thing sound like a coffee grinder. You can check rod bearings rather easily though.

    Also, previous owner changed over to premix....I wanna go back to injection. Anyone got a pump/gear/tank/hose/cap they'd sell me?

    Pretty sure I've got the oil tank and sender. You can have them.

    I'll look for other stuff on your list.

    Pro 785 - TBone

    Started breaking it down tonight -

    Reeds look good:


    Carbs are probably gonna need a rebuild - been sitting for a while - I'm gonna open em up:

    Actually, looks like new rebuild inside the carbs, may be able to just clean em up

    Leaning towards going ahead and pulling the engine to check crank, leak down etc....

    Looks like there is some rust on that crank.
