Our FORGOTTEN 750cc Powered Cross Kart Returns to FULL POWER!

Our 750cc cross kart build returns to full power! We bought a 1982 DOHC Honda CB750 motorcycle for $150 with a stuck engine. We found that the half of the valves were rusted solid, so we serviced the head, and reinstalled it with new gaskets. In today's episode, we find our CB750 power plant doesn't have spark, and doesn't idle. We change coils, check timing, and rebuild the carburetors until eventually it runs right! And STRONG!

Thanks for Watching!

    I'm going with a couple ring lands are broken, the fact your only using 2 carbs when u should have 4. Maybe its not getting the correct gas mix per cylinder. I didnt see any compression test or leak down test. It could be bad valve seats. Theres something that yall are missing for sure. I Love the channel, but I wish I could be there to help you pump out more content and get everything running correctly. ❤

    Loving this machine. In agreement with comments below about the intake setup. It's a huge restriction being half the carbs needed for the engine as compared to stock, plus the intake branching is not exactly efficient. This thing would slap so much harder with a set of four FCR's. Still a fantastic bit of kit, no matter how it's sliced tbf. Keep it evolving. =]

    One thing is for sure you either don't give a crap about your health or you are just plain stupid or abit of both. I am speaking from experience. For years I subjected my self to engine fumes Im 65 now and if I enter a room with an engine or a space heater is running my throat swells shut and my face and ears turn beet red and my face feels like its on fire. I become deathly sick in minutes from an allergic reaction that I have no dought would put me in the hospital if I do not get fresh air in minutes. This reaction came on over a period of subjecting my body to toxic fumes and now I can look back and see how stupid I was. Same with eye protection twice being in a hurry, I had to have metal slivers removed from each eye. One has a blurred spot to this day from a scar that has required me to wear glass's to drive. So, I am no stranger to stupidity I only wished there was some way to get others to think more about their safety. I can say it is truly not worth it. But; u-know it will never happen to you, Because; your Superman with a capital S stamped on your forehead when your younger. Only it's not truly Superman it's really more like STUPIDMAN.

    The whole Alcohol In Gasoline Causes Problems After Storage is a myth.. We have never had alcohol in petrol in the UK (nor Europe as a whole?) and every time I go to rescue an engine that's sat for a year or more with fuel in the carburettor and/or tank there's varnished fuel in the bowl, the emulsion tube is fubarred, the jets completely gummed up and the tank internal surface treatment is dissolved (and the gas a horrible green colour). We only have 95 and 98 RON petrol and none has alcohol (or maybe there is alcohol at the petrol station but I've never seen it and never not had the choice of alternatives).

    How many engines do you have of that type ? Break them all down . Assess the parts . Rebuild one engine of all the good parts . With the expertise the three of you have now . You can have a really good engine . Hell you probably can put two together . Obviously one better than the other . Don't be afraid you've broken down stuff before . You got this . Only get a new engine if you want the new project

    Newer Suzuki GSX-R motor. More power, fuel injection, easy to come by (and cheap), liquid-cooled, reliable. Probably better for the application. Especially since there's not really any shortage of wrecked GSX-Rs around. Or even an older carbureted one. But, the fuel injection is a plus IMO.

    I am thinking two options: proper carb synching with a mercury tool or similar device and/ or ditching the CB750 all together and going with the tried and true (from the same vintage) KZ1000 as a used and abused privately owned, or bought used and abused and it still ran strong Highway Patrol issue donor motorcycle. Those Kawasaki's have ran the gauntlet privately owned and commercially owned and still to this day I see them occasionally on the road 40 years later. Better yet, get a hold of an H2 750 or an H1 500 engine and.... Well if you are familiar with them, enough said.

    im betting that engine is fine, some times the oil control rings have crap in them and after a few hundred miles they stop smoking unless the oil seals on the valve stems are shot, which has nothing to do with compression, all cylinders must have the same compression, or your wasting money

    Hey guys. First step in a good tune up is to confirm compression is balanced across all cylinders. Within 10% of each other. Second thing I see is you are trying to feed 4 cylinders with half the carburaters the bike came with.now that u have a sonic cleaner surely u can find 2 more decent carbs to put it back to stock configuration. Third(and this is just my personnel opion) put some bigger tires tires on that thing! Get it up outta the weeds and make it roll over obstacles easier! Keep up the good work.i enjoy ur channel.

    It is very important to have all 4 carbs in sync VERY in sync I think this has been your problems all along. You need to have the all 4 fuel screws turned in or out the exactly the same. You can buy a carb sync tool. DONT BUY ANOTHER MOTOR UNTIL SOMEONE HAS A BETTER UNDERSTANDING OF TUNING CARBURETORS.
