When I got the bike each air mix screw was set at exactly two turns out -- which indicates to me that the PO never adjusted them -- he would have adjusted them while syncing, so I'm sure he never did that either. Not seating the boots also indicates general sloppiness which also leads me to...

Stabler, you were right, air leak. The previous owner never put the carbs all the way into their rubber manifolds after he re-built them. They were about a quarter inch out, which meant that the little lip in the rubber wasn't slipping into the groove in the carb body. He hadn't tightened the...

Yesterday I finally got around to fixing this problem. Sure enough, the relief hole in the master cylinder was clogged. So, it took zero dollars and about an hour to clean and rebuild the cylinder re-using the old parts to fix the problem. What I don't understand is how the brakes worked at...

Thanks for the response. I guess I was looking for a magic bullet, and hoped that new lines would be it. What it probably really needs is for everything, both calipers and the MC, to be re-built. Will be a while, but I'll report back with what I find.

My front brakes lock up over night. I can relieve the pressure at either bleeder -- just a very small amount of brake fluid escapes -- and then I'm usually good until the next day. I am no stranger to master cylinders with plugged relief holes and to calipers with stuck pistons, but this seems...

Thank you for the response. I'm beginning to think that I am going to have the problem fixed by a local expert. I am very good with carbs, but I think my time is better spent working on '70s era Yamaha twins, which is what I do and which I know well. There is a local retired Honda mechanic who...

My first CB750. It only has 2,715 miles! When cold it takes forever until it runs without the choke, and it won't go below 4000 rpm when warm and riding. It will eventually come down to normal idle when I put it in neutral, but it takes a while. Barely ridable like this. I've done a little...
