Well, it looks bad. I jacked the bike up and put jackstands under the rear sets. Took the spark plugs out and tried to hand crank the motor by rolling the rear wheel in each gear, wouldn't budge. I even lifted the bike's rear end up by one of the mag wheel spokes and it would not move. Took the...

I think you are right. I just tested everything again and made sure the leads to the battery terminals were all secure and tight and that nothing was improperly connected. I turned the key and there was no pop or noise. Turned the key off and back on and this time I heard it come from the...

I've got a '73 CB500K2 I had rebuilt professionally, including a top and bottom half of the engine. Everything has been put back together, with some professional machine work so I could integrate a Ducati swingarm and CBR600RR fork up front. Installed the electrical loom on the outside and...

There are several things to check here. If you replaced the carburetors or installed new ones, they most likely have factory jets in them.

Sure thing. Got the pistons fairly clean last night, and a lot of the caked on hard carbon deposits on the valves removed just by soaking and cleaning with a nylon brush. I'd like to do a compression test though too, but ill go with your recommendation first. It looks like the cam chain...

Hey guys, I joined a while back but haven't posted in a while. I do have a few questions about doing a rebuild of my 500F motor. I started this on Friday night last week after giving some consideration to it. I've been restoring the bike from a mediocre state that I bought it in a year back; new...

I've tried numerous ways and types of fuel lines on my CB500F, but there does not seem to be enough room under the tank petcock valve for the fuel lines to be used with inline filters without kinking. Right now I'm using Motion Pro lines I got from 4into1 with some small plastic inline filters I...

Just signed up moments ago after having visited this site a number of times for knowledge and general "know how" info while rebuilding my '73 CB 500. Now that I am largely finished, I look forward to interacting with you all and possibly running into a few of you at Backfire every month. Cheers!
