    Desperate for Help!! — 1978 CB750F keeps dying

    I'm at the end of my rope with this bike.... I've been chasing this problem for a year, and in that time I've spent countless hours reading through forum posts, replacing parts, and taking it to different mechanics, all to no avail. Here's the issue: My bike starts up and runs fine, but on a...

    CB750KZ 1979 and CB750F 1979 Engine Differences

    I’m trying to understand, what if any, difference there is between the engines on the 1979 CB750K DOHC bike and the 1979 CB750F DOHC bike (called the CB750F-A in some markets). I was sure that I had read somewhere that the CB750F DOHC bike had different cam profiles and larger valves than the...

    Looking for a bit of advice on a 1976 CB750F

    New to the forum, my name is Dave Clark, from Columbus Ohio. I have a stock original condition 1976 CB750F, with 7,900-odd miles. Running and riding. I thought I was going to use the motor for a 70's 'Jammer' hardtail frame chopper project, but I think that would be a terrible thing to do...

    Here she is, picked up today. A 1979 CB750F SuperSport. The GL1000 that I last rescued will have to move to the next room for a while I guess. Had to remove the calipers and pull the bake pads out to get the wheels freed up to load/unload it. Before I took it in the shop (basement garage) the...

I finally got a chance to ride and found that after about 20 min. running time 2 and 3 would cut out, after a few min. running on 1 and 4 it would kick back in and run good for quite a while sometimes and other times it...

    Obsolete con Rod bolts

    Hi all, I am rebuilding a 1980 F model and everything I have read suggests replacing con Rod bolts is a must. Unfortunately they appear to be discontinued and I can't source any. The part number I have is 13204-689-004. Surely there must be a superseded part number or another one that will...

    Must've done something ass backwards because all four carbs are overflowing. Now I've put floats in upside down before and had to correct them, but these floats look like they're made to be fool proof. The floats are all plastic and have a groove that 'look' like they hold the float needle...

    '80 CB 750 F SS has been in the garage since maybe 2005?

    II'm finishing up an '82 Maxim 650. Made a hardtail out of it. Solo seat, etc. Waiting on some jets to arrive. Running lean. When the XJ is done, I'd like to get the Honda going. Last time I had it running I felt the clutch going out, and the timing chain sounded like it was slapping around...
