Soooo the engine seized on the 750 today and my mechanic says there's no hope. That being said it's time for a project. He's recommending we throw a triumph speed four engine in her. Getting some feedback from y'all

Gas is slightly dripping/pouring from the bottom of the carbs. I know it's a safety mechanism but it's pouring too much for it to be normal. Will my carb rebuild kit fix this problem or do I need to go into more detail

So this is my first post on here so give me some slack. I just got my 1979 cb750 cafe and it's been a hastle from start to finish. Most recently I was traveling on the highway and was push 75-80 mph and all of a sudden a very lowed and consistent 'chopping' or 'pop pop pop' noise started and I...

Hey Guys, I'm in the middle of a rebuilding a CB750 1981; This is my first ever build and It's been a whirlwind of forums, google, youtube and a local motorcycle shop to get me on track to this point. However, I've hit a bit of a snag; the bike wont start / fire, and I wondered if any of you...

Garage build over the past year...thanks for checking it out. The goal was to keep the frame and mounts stock to be able to go back to original if desired but still customize it a bit.

Hello all; new member to the forum. Wanted to log my build on my two CB750's that I picked up this past weekend, been wanting to do a CB build for the last couple of years and came across a deal on these two bikes that I just could not pass up! Ended up getting both bikes and almost four of...

Intro... Picked this up just before Thanksgiving weekend. 78 CB750K. 14k miles. Been sitting in, and next to a barn for 25 years, or more. Goal is to get it back on the road as a reliable rider, and enjoy as an original survivor. Maybe put some flat bars, and give it a more muscle bike look...

Here she is, picked up today. A 1979 CB750F SuperSport. The GL1000 that I last rescued will have to move to the next room for a while I guess. Had to remove the calipers and pull the bake pads out to get the wheels freed up to load/unload it. Before I took it in the shop (basement garage) the...

Hey Everyone, Thought I'd post the story of my 1977 CB750F. All my moto-buddies have newer bikes, and all of my gearhead buddies are into 4-wheeled vehicles, so I'm hoping this forum will be a nice way to keep track of what I've done and maybe get some emotional support! I bought my bike...
