Hello, I am the second owner of a 74 CB 750 K4. The bike was neglected by its original owner. He bought it 5 days after I graduated from high school on June 20th 1974. At this time it has 17,361 miles on it. I estimate that I have about $3,000 into it. The OEM exhaust alone were just over $1,000. If you are rebuilding/ restoring a 750 try David Silver Spares in England or cmsnl.com out of the Netherlands. Once it warms up it runs like gangbusters and pulls like a locomotive. Here is my delema, I rebuilt the carbs using Keyster kits. I have heard from other on line boards that many aftermarket carb kits are crap. When I go to startup it is extremly hard to start and keep running. It kind of acts like its not getting fuel. I had a problem before with rust in the tank. I have completely cleaned the carbs and used KBS coating inside the tank. It is like Kreem but much better. It won't destroy fresh paint unlike the others and works great. It seems like the idle circuit is not dialed in properly and the mixture screws may not be adjusted right. Any carb or tuning pros out there? Thanks for help in advance. And here are some pictures of my old horse.
