M&M motorsports in Westmont, west burbs, work on nothing but older bikes. When I first bought mine I had them do a few things on it. You might want to try them.

Just wondering what front ends are compatible with a 78 cb750k? I am looking to purchase a front end off a 79 cb750f that has dual disk brakes in the front. However, I am not really fond of the wheels on the supersports and would rather use the wheel that is on my bike. Does anyone know...

Bump! I can ship most parts for around 20 dollars or under. Parts will be going on ebay this coming week. I can accept paypal.

I can try to get the shipping costs by tomorrow. I'd do 25 bucks for the pair + shipping.

Going to search around a bit more to make sure there isn't anything else I haven't seen that might be a better option but I do like how this one seems to work. side by side gauges seem like they would be harder to compare and I have read reviews about how some do nothing but jump all over making...

This one uses stainless steel rods. Here is a video I found of someone using it. seems like it works ok. http://www.youtube.com/watch?v=3k5I-Oz3Uug

I am looking at getting the morgan carbtune pro. its 100 bucks shipped to door. not too bad imo. Anyone have this one?

I am looking at purchasing a good brand of carb sync because the shop around here wants 125 to sync my carbs. I have a friend that also needs this done so we are just going to purchase one together rather than spend 250 to get it done. Just curious if anyone has an opinion.

If people are still looking I have a set of stock exhaust pipes for sale in the classifieds section. Not asking nearly what they are talking above but they need a little tlc. I can send a picture to you if you pm me your number.

haha I am right there with ya. I live in an apartment while in school and the lot got too dark for me to work on it anymore tonight.

I am in the process of putting on the dnya s ignition system on my 78. From what I have read in the instructions I received you are correct about Blue wire for 1 and 4 and yellow wire for 2 and 3. However, the directions do not indicate which terminal on the coil is for which spark plug, which...

I recently bought a 78 cb750k and it came with a bunch of spare stock parts. I can get you pictures just pm me. I have a rear fender in good shape with license plate and brake light, no dents. just needs a polish. (Brake light plastic is broke) set of stock gauges (tach and speedo) they work...

I have stock sprockets (18/48) on my bike and riding at 55 in 5th is revving quite high. Just wondering what rpm you guys like to cruise around at? I was thinking of going to 17/41. This would take me from 2.67 to 2.41 on the ratio. I also read somewhere that using prime numbers for sprockets...

I know cycle x makes a nice one. Check it out.

Yeah I was just thinking about doing it that way. Its dark out now so I might have to wait until tomorrow. Maybe I can sneak the bike into my apartment without people or my wife noticing. haha

All I am seeing online is that I should be getting the 35mm size... just confused as to why the manual says the forks measure 39.5mm? is that maybe the thicker part of the forks that they are referring to?

As title states, what is the fork size on a 750k8? I plan on ordering a pair of clip on bars soon and I really don't have anything to measure the forks with. I found in the manual that says they are 39.5mm? If they are that size, do I get the 39mm size clip ons? Also, what places would you...

gotta start my build sometime! I'm in!

So, I believe this is happening to the bike I just bought under hard acceleration. I was wondering how difficult the diagnosis is and the repair? I have rebuilt a c6 ford transmission that is good for 800hp but this is my first time working on a bike. Any help/pointers would be appreciated.

I was thinking it was maybe a loose valve. I think its on the left side of the motor that's why I had my phone on that side. Thanks for taking a look.

I also drove it and it has, from what I can tell, all of its power. It is definitely faster than what I expected it to be when I bought it last Sunday.

Ok so I had to put it on youtube... not really sure if you can hear what I am trying to get you to hear but its worth a shot. The first time it dies is when I tried to rev the motor... Also I took the gas tank off before this and noticed this bolt sitting inside a hose that comes from the...

So I recently bought a 78 CB750K and changed the oil and filled it up with 93oct gas since it hadn't been run in quite a while. I have zero experience with older bikes, but to me the engine does not sound totally right. I don't know if there is some sort of knocking going on in the motor or...

Thought I would add a picture. I got it running tonight fairly well. I noticed that the exhaust wasn't completely tight to the engine so I tightened that up. It got a little too dark to see if gas was still leaking from the carb but I plan to check it tomorrow afternoon. I took it for a...

ride as-is the rest of the summer/fall. then maybe tear into a few things this winter if I have time. I am going to pharmacy school so not sure I will have too much time. Plus I live in an apartment and not sure the wife will like it sitting in the spare bedroom or the patio. haha

They gotta be. Its just a bunch of random crap that has nothing to do with this forum.

Hi, I finally joined the forum now that I have finally found and bought a bike I liked. Today I drove about 350 miles round trip to purchase a 78 CB 750K. I got it for a pretty good deal and it came with a lot of spare parts including an original set of gauges in near perfect condition. Not...
