When I turn tightly I drag exhaust where the 4 combine into 2. I'm a big guy and suspect it may have something to do with my rear suspension, and/or needing to adjust how the exhaust hangs... Any suggestions?

So I drained the fork oil last night and replaced it... The manual said 6.5oz each fork, I got just barely over 6oz out of both of them. The bike rides WAY different now! As a side note, the wife wasn't overly pleased that I used her measuring cup... apparently it's now my measuring cup, and...

While working on my brakes I discovered the bleeder valve was mostly stripped. I ordered a replacement from my local honda shop and when I went to replace it, I found the one they gave me was too big! They both fit an 8mm wrench but the threaded portion of the replacement was 1-2mm bigger than...

So when I got my 78 CB750K the front brakes didn't have any juice in them, there was a rag tied around the master cylinder, and when I asked the PO why he said it was to stop brake fluid from getting on his dress pants... Since then I've torn the whole 9 yards down and built it back up. I...

So going through the things that aren't working right on my 1978 CB750 I found that the turn signals don't blink. I assume this has something to do with the relay either being bad or the bulbs not drawing enough juice, I have a few things to try to fix it... but I was looking at the wiring...

Are there any guides or advice for how to rebuild my master cylinder? I was looking at it today and couldn't figure out how the heck I'm supposed to get it apart... Special tools needed or something? Thanks,

So I look out this morning and there's a gas puddle under my bike. My first thought was I failed to turn off the petcock again, but upon inspection this was not the case. As I was looking over the bike I saw a stream of fuel start coming out of one of the hoses that drain from the carbs...

So working on my 1978 CB750K and I find that I'm apparently a little bigger than the riders they designed it for. Sitting on the seat right up on the tank just isn't comfortable. I'm a big guy already, so I won't be riding double due to weight constraints, and was wondering if someone could...

So looking at options to rebuild the brakes on my 1978 CB750K and I found the complete aftermarket master cylinder for $100, but the bit about the brake light makes me wonder how one then connects brake lights to this system... For $80 delivered I can get all the parts I need to rebuild the...

So I mentioned this in the overall thread about my CB750K adventure, but I thought it warranted it's own thread. My rear brake doesn't work when the bike is on the center stand. It does however work when the bikes on it's own two wheels. Is this normal behavior? If not is it something I...

So looking at threads on this forum has been great motivation to work on my bike. It's amazing seeing something so old come out of storage and end up looking so awesome. But I topped that feeling yesterday when I was at the Honda dealership picking up some fuel line. When I stepped out of the...

How fast should fuel flow through this? Steady stream, trickle, somewhere in between? My manual doesn't show anything about removing/replacing it, and I suspect it needs cleaned out in a big way. Are there any seals I need to worry about when doing this?

So I'm starting the rebuild on my bike and the front caliper is frozen. I don't know if it will be salvegable or not, but I was wondering if anyone could point me towards a replacement similar to what vintagecb750.com sells for the master cylinder. When given the choice between spending $50 on...

So I'm new to this forum, new to motorcycles overall. Back in 1989 I owned a 250 enduro, in 1992 I bought a Kawasaki to restore and then got deployed to Germany, no title, so I couldn't keep the bike... Fast forward to yesterday, my old boss IM's me and asks if I am still interested in his 78...
