Barn Find CB750 health check and tune up! Now that the bike is up and running I am working to make sure it's sorted mechanically and getting an idea of its overall health. In this video I show the condition of the cylinders, do multiple compression checks, adjust the valves, sync the carbs, and diagnose an oil overflow issue the bike was having! I give this bike a 95 on the 100 scale for condition. For now all that's left to do are small jobs and simply enjoy the bike!
Compression figures:
Pre first start cold: 100 / 120 / 120 / 80
After 60 miles cold: 140 / 151 / 151 / 145
After valve adjustment and 75 more miles cold: 149 / 125 / 135 / 145
Warmed up figures: 165 / 160 / 165 / 167 = FANTASTIC!

This is Steven England Southwest England 71 years old and I watching your videos and I think you do brilliant. I don’t care about your little mistakes. I think you are ace on everything you do. Keep going to give up.

This is SO much fun to watch. Honda’s are such legendary motorcycles that if properly maintained they can run forever. I’m telling you that if I was nearby I’d have volunteered to come help as I’m sure Many other subscribers would. Sets cover coming soon? CBX! Yeaaaa 😁👍🏻

Great job in putting this legendary motorcycle back on the road, where it deserves to be. Sounds really good too. The only upgrade I might make would be dumping the points in favour of electronic. More accurate, less to go wrong and nobody sees it. Really enjoyed the whole series and look forward to other projects. Good work!

I've been working on my 1982 Honda CB750K that's been under a tarp for the past eleven years. 1st on the agenda was to empty fuel tank (left it on the bike). Used my Pennzoil fuel transfer pump. Carbs were run dry at shutdown which probably saved the carbs ! Filled tank with two quarts Marvel Mystery Oil and then topped tank with fresh fuel. Left tank sit several days. Emptied tank and filled with fresh fuel. New oil filter and oil plus new air filter. Start up time. Open fuel cocks. AMAZING.....engine fired up second crank ! Now that I know it runs it's time for cleaning, polishing, repainting miscellaneous items ( Rustoleum charcoal metallic). Currently painting with the metallic and plan to use Crystal Clear for final 2-3 coats. Next up......new levers, mirrors, hand grips, horns, headlight and headlight housing. Also adding Nilite LED lights. Should sparkle when I'm finished. JimInCincy

Totally love your videos. This one tugs my heart strings. I am a 69 year old Aussie, and I bought a brand new CB 750K2 in 1973 when I was 18 years old. I rode a lot of miles on it. From Mildura Victoria to Cairns Queensland when I was 19 (Google that, it was a long ride) plus heaps more. That Bike was like my first love. I am now an old man but still own 6 Motorbikes. Four BMW’s, one Triumph and my most recent purchase is a K8 Suzuki Bandit 1250 that I am having an absolute blast on riding Twisty roads. Keep up the great entertainment with your videos and you will keep this old man happy.

Was thrilled to see the follow up on this iconic SOHC. My best friend had one in the late 70's that he dearly loved and had for quite some time. Had forgotten just how sweet they sounded when they were in good tune. Thanks for sharing the trek back to bygone days.

Great video! You do a great job of sharing the process - sometimes fun, sometimes frustrating, always rewarding in the end. I've done quite a few vintage bike rescues (just finished up a 1979 CB750K) and it's always a good day when they're dialed in and running like they should. Looking forward to more CBX videos. Thanks for sharing!

Great video and in no way excessively long. I love the fact that you’re keeping the patina. It looks like a proper old bike, well ridden, maintained, but not doted on.

Great video. I enjoyed this from start to finish.

Great video! It just goes to show how tough these SOHC engines really are, and I always liked the mechanical aspect of setting the valves & cam chain, & synching the carbs(wait'll you do your CBX carbs!)to get it all dialed in and running bitchen! We all have made mistakes in the process of doing adjustments, recall lighting off my fresh 1270cc CBX engine with a lot of expensive parts in it and it was running on 4 holes, turned out to be valve clearances, reshimmed and vroom! Rocketship.

It is videos like yours that give me confidence to approach very much simpler tasks to accessorize and maintain my new NC750X. Impressed at how you diagnose your mistakes and own up to them, but this is just an aside; the real take-away is your normal patience and thorough, methodical process to get it done. Really impressed with those compression numbers. That barn find really turned out to be a gem, didn't it?! Congratulations on reviving this bike so that you can enjoy riding it.

Thank you for this series of Honda clips. I especially like that you share thought, theory's and tests even ones that not go so well. We all do them you just do them especially well.🙂
