I have a 1981 CB750k that I've recently put back together after disassembling for paint. I took it out for a short test ride, but it seemed to be very hesitant and sputtery when trying to open her up or accelerate. When i came back from the ride i noticed a small spot on the floor under the...

At some point after the riding season begins, I will have to replace my rear tire. Will save money and downtime by removing the wheel myself. Bike has the original 4 into 4 exhausts.

Need a replacement fuel petcock or rebuild kit for a 1983 cb750sc. It leaks in the run position and reserve position. Does anybody know of a good source? I removed the vacuum from it so thats not an issue but I cant figure out what fits because nobody seems to have anything that lists...

Howdy ya'll I Purchased a 79' CB750K last spring and when I finally got it running n' driving I noticed that there was no fifth gear. Meaning, above 4th, it just didn't go anywhere. Did the research figured it was the shift drum stopper (maybe one of the pins fell out). I opened it up a few...

If I remove the cylinder heads to replace the gasket will it decrease the compression when I put it back together? My thinking is the rings are seated and if I remove the head it will mess up the seal. Are there any ways I can fix the leak without removing the head? I’ve heard of people using...

Hi All, I'm new to the forum and have had several vintage bikes over the years. My pride and joy is a 73 Kawasaki H1 that I take to Barbers every year. Last year I sold my 82 750F and immediately regretted it so I found a replacement: a 82 900F (Black/Red)with 14K miles on it. Generally in...

Hi guru’s. Just scored a sweet little 79 750F. Been years since I’ve had a Honda, so I’m really rusty. Ordered a service manual but it won’t be here for a few more days. What’s this little gem leaking a black tar like substance on the battery? Also, how the heck do I get the little Phillips...

Bike has an aftermarket master cylinder, however, I have the original that needs to be cleaned and rebuilt. Having a problem removing the plastic reservoir. Appears that all the fasteners are removed, but the reservoir is stuck. Perhaps the large O-ring has bonded to the metal body. hesitate...

Is the oil seal behind the rotor coil serviceable without removing the motor and splitting the case? And is a minor oil leak/drip in this area detrimental to the coil, stater, or brushes? Any info or advice is appreciated. I just finishing up installing a new rotor, and stater coil, don't want...
