Hello, I am selling my 1972 Honda CB750Four. My grandfather purchased this bike brand new in 1971. It sat for a while until I fixed it up a bit and got it running. I put new tires, new chain, cleaned the carbs and a few other things to get it back up and running a few years ago. After having a...

I have a 72 CB750 in Orange, CA. Currently is not running. Want to get it checked out and am looking for someone in Orange/Corona area. Thanks.

haha your cat picture is perfect for you. But ya, maybe not amazing but it ran good for a 40 year old bike, and im just comparing it to other bikes I have been on both old and new. Never felt like i was getting the full potential though thats for sure. But Im just gonna have to take it in. I...

ya just did a compression test again and I'm getting 85-90 on all 4. Maybe I'll try to get some of that Restore stuff. I really dont get how if my compression has been that low how my bike sometimes runs amazing for weeks when "I'm really lucky that it even starts." I'm pretty sure I'm doing...

Ya I did a compression test a while back it they were all really low. One person said that the bike shouldn't even run that low and some others said that old CBs can be really low. So I don't know what to believe.

ya they are pretty black. The other two are a lil black too. im ordering new ones but is that whats causing the problem?

So I just checked my coils and spark plugs after having some issues and everything is fine. Now for some reason when I start he bike it only runs on cylinders 1 and 4. I have to turn the idle up just so it can idle. After trying a few things I turned off the fuel at the petcock. A few seconds...

Ive kinda had this problem lately. But i have new coils on it. Did you ever figure out the problem. Mine starts up and runs ok and then after about a 20 minute ride once its gets really warm, the bike started running very bad. Almost like it was running on only a few cylinders. then after...

Ya I like them on that bike. I saw that on Jay Lenos Garage. I say if you like them and want them then do it! Its your bike and whatever makes it original I'm all for!

Ok, so I hooked up the exhaust back and it's flush on the headers. So I start it up and let it run and is sounding good except now it seems to be getting too much fuel!! It's coming out the overflow. i haven't had that problem since last year when I got the bike and redid the carbs. Geez...

Ya it's hard to tell in the video. But it defining rely only makes the rattling sound after being warmed up a while. Sometimes it even takes bout 30 minutes or more. whats strange is that just today after I tested the compression I put everything back on and tightened the exhaust as best I...

Yep throttle was all the way open. The bike wasn't warm, if that has anything to do with it.

Just did a compression test and all four are pretty low. Like 70-90psi. I'm about to check the valves now. Basically trying to do everything before taking the motor apart, Which is one thing I don't know how to mess with . So I'll probably have to take it into a shop which sucks cause I...

Ok here's a video of what I'm looking at. The one exhaust is a little off the header, I can't put it flush because the pipe is slightly bent. Anyone know a way to bend an exhaust pipe? Also the black stuff on the engine part does that mean that there is a blown gasket or something in the...
