    '79 CB750F Super Sport / Engine Finish

    The engine of my restoration functions well, and all it needs is to recover its original shine. This is the silver-painted version, but I'm not interested in re-painting; can I soda-blast the engine as a unit ? ( engine has been removed from frame ). All openings ( exhausts, carbs, etc ) have...

    How do these bearings look

    This is my first go at an engine rebuild and Im torn on if I should replace both rod and main bearings. Engine had 36k miles with low compression on all cylinders.

    Idle runaway when I blip the throttle

    I recently finished rebuilding a 1982 CB750C; body, electrical, engine, carb, etc. I fired it up for the first time the other day and boom - she came to life. That was cool. Everything seems to be okay except for a problem with the idle/throttle. I can start the bike and it idles okay, but when...

    Just got a free one!!!

    So a friend was looking to get rid of a "mystery" bike. I had no idea what it was. For free, just needed it out of the yard or it was going to the dump. It ran a year ago, sat outside this winter in VT. It was mild. He just wanted to pass it on to make it useful. I said at the least I...

    New member, 1981 CB750K

    I haven't rode for a while. When I was 14-15 I used to "borrow" my father's Honda 750, it must have been a 73 or 74. Great memories. Found a 1981 CB750K with 18K miles on it. Rode it home, but I want to get a fuel filter on it before I ride again. The seller let me know that he pulled it to get...

    1974 CB750

    So I'm new to the CB750. I've restored a KZ900 and am currently working on a CBX, so have some experience. There is a 74 CB750 near me with 11k in what is described as very good original condition. The pictures back that up, but to do a full nuts and bolts restore will cost way more than it's...

    Getting ready to ditch the pods, and go back to the OEM airbox. I will be going thru the carbs again, want to double check a few things. When I rebuilt them the first time, the O-rings for the fuel cut offs were the wrong size, diameter was ok but the cross sectional thickness was thinner...
