Abandoned $150 Honda 750cc Build | Will it FINALLY RUN?

We bought a 1980 DOHC Honda CB750 for CHEAP! The DOHC 750cc engine had a hard spot in the engine rotation, which we found out was due to multiple stuck valves in the motorcycle engine's head. We service the head by installing new seals and cleaning the valves, and reassemble the engine with new gaskets. We shove the 750cc engine into our cross kart and see if this abandoned CB750 engine will run!

Who else wants to see the cross kart vs trophy truck at Busco Beach. Like so John and Ike will see.

[@bradleyj.fortner2203]

Not a big fan of the cross kart. Little wheels, no ground clearance. I'm amazed it took them as long as it did to smash something on the bottom of that thing.

[@TheBestOrion]

@@bradleyj.fortner2203 yeah, it definitely needs more ground clearance. Still cool imo.

[@barndawg707]

@@bradleyj.fortner2203 Just needs better ground clearance and a skid plate to protect the engine. It's a HOOT!

[@BROKEN.WRENCH.GARAGE]

Yessir!!

[@ActivityPhoto]

The difference is these guys are no teenagers but they still approach things like they are. Did anyone see them try to lap the valves or check the clearances. Then they kept the starter button pushed until I'm sure the starter was over heated. A little starter fluid would have helped a bunch. Don't get me started on the condition and lack of equipment in that so called shop.

[@garageofscrap]

@@ActivityPhoto you don’t need lots of equipment to do something, a decent mechanic can work with very little to achieve what they want. And just because you didn’t see them do something doesn’t mean they didn’t do it, if you watch Isaac’s channel you will see that he’s a highly skilled mechanic and wouldn’t try to start an engine without correctly setting up the valve train

[@bocabral1433]

Yes it's okay to crank them and let them idle to make sure it's going to run before wasting any more time if it's not. But however it's not good to Rev on them without the exhaust.

[@bocabral1433]

I was okay and understood why you did everything you did. But you guys let me down this time what happened to getting the exhaust on and a test run ? Okay I guess it was a way to get us to come back and watch another one to help support the channel that much more which I watch everyone anyway.

[@CarsandCameras]

Question time: is it time we start spending big money for engines that we KNOW work, or do you like the trail and error process with these cheap non-runners?

[@carter.s9678]

Trail and error

[@looshskadoosh2369]

Every once and a while it would be nice to see you guys buy a real nice new motor but for the most part, trial and error is the way to go. Also, I hope you guys have a wonderful Wednesday!

[@gokartbob6478]

Both, just do what you want.

[@discingaround]

Mix it up! Maybe do a comparison video of a new and used/not working engine. Show the ups and downs, the spend on each side, and which one the team prefers.

[@garageofscrap]

Would be cool to see one or two high powered modern engines like the 919, but I like the trial and error revival style videos

[@rjc862003]

put proper carbs on it jesus at nearly a Million subs you need to be upping your game

At least the aluminum Y intakes like Moto Migs did on his

[@nielsdebakker3283]

If I followed correctly they have the original carbs but they wanted to wait fixing them carby's up until they knew this engine was a runner. So no more excuses, we want to see and hear that engine scream on its original carbs.

[@robertschemonia5617]

Agreed. And sync them! I have an 81 KZ750-4, and I was amazed at how much better it idled and how much more low end it had after I synced them. Kinda sucked, but was well worth it in my opinion.

Would like to see you guys get back to doing more revival videos. Getting old engines and getting them going again. Is a bit more relevant to some of us low budget builders, and being in Australia aswell engines and parts aren't as cheap new here. And the challenge and the knowledge learned along the way from reviving an old engine. It seems more satisfying to me starting an old engine that hasn't started in quite some time. And seeing just how bad some can be and still run😁 Would love to see more like your earlier videos.

"Mushroom the heads of the valves gettin' em out"...get some brass punches. The brass is softer than the material of the valve. It will help prevent the head from mushrooming, and works just as well on bolts and other such things that deform easily when met by the hard face of a hammer.

[@dave1135]

What I've done to get stuck valves out is spray inside the intake and exhaust ports with Wal Mart choke cleaner, it still has that "old school" bite that will dissolve the carbon and varnish. Gumout cleaner doesn't have the same strength. I'll then tap them down, spray the stem, tap it back, spray, tap again until they get loose. If the valve is rusty, I'll substitute kroil for choke cleaner

[@ardinlovett4359]

You guys could use a carbide valve seat cutter with slightly larger valves. Heavier springs ect.
