Hello, I replaced the carb intake insulators on my 79 CM400A a few years ago with some aftermarket ones from an ebay vendor and they're already getting pretty ratty. Does anyone have a good used set? I also need the left and right mufflers, both have holes in the bottom. Seems to be a common...

Greetings! I found this site after two weeks of reading everything I can about the above mentioned bike. Here's the story if you want it.... "I've got an old Motorcycle out in the shed if you want it." Said a friend of mine who is trying to downsize. "Of course!" I replied as nonchallantly...

Hey all! I'm looking to sell my 1979 Honda CM400T soon or at least this year. Being 38 years old, I wasn't sure if "Bluebook" value was accurate. I replaced the clutch cable, adjusted valve clearances, oil change, carb cleaner, carb synchronization, etc. The bike runs great. Thoughts...

Any idea what this horrible noise is? It appears to be coming from the lower end. This 3rd video is after adjusting the cam chain tensioner as per the manual. It sounds much worse..

Folks, I'm going to document everything I'm doing here and post a lot of pics. I'll mark questions with a *** before and after the question so that anyone just looking to address issues and not read the rest can easily see when I have a question. I'll try to edit this Original post with answers...

Good afternoon folks! I am new to the twin world and I picked an admittedly leak prone bike (according to most mechanics I've spoken to). I have a 1979 CB400t II and I have it running like a top and safely at this point (again, thanks to a great mechanic). Next on my list is to start tackling...

I have a question...what did the original mirrors look like on a 1979 CM400A? The mirrors on there now are tiny round and vibrate out of usefulness before the bike is out of the driveway. I've seen 3, 4 and 5 inch-round, oval and rectangles with straight and bent mounts... all claiming to be...

I need to replace my carb boots and of course the boots for a '79 CM are very difficult to find these days. I really do not want to spend $100 bucks for originals, but... What I need to know is what other models of bikes have the same part that fits a '79 CM400T. (we're talking carb insulator...

I started researching tires for the 79 CM400A and I am having troubles. Some folks are calling for tube tires, some tubeless (it's got tubeless on the Comstars now), I can't seem to find a matched set, a lot of the recommendations I have found are obsolete and no longer made or the links are...

I recently got a 1979 Honda CM400A, mostly for my wife to learn to ride on, but also because I love the look and the Hondamatics always seemed cool.... Anyway...the previous owner had a meticulous garage full of all sorts of vehicles and was doing maintenance on several when I arrived for...

I just picked up a great '79 CM400T and rode it home 6 hours! The bike ran like a champ the whole way back, even over a mountain pass that goes to 12,000 feet! My question is this: I basically have a very limited tool selection right now and would like to put together a tool box for wrenching on...
