Never unscrew a camshaft this way. The valve springs are pushing from one side and try to bend or break the camshaft, even though these camshafts are relative short. The last bearing block may not take the force of this leverage.
@@vrooom666 Definitely generally true. Just wanted to add, for others benefit, that service manual will also typically list the order of tightening/loosening.
No. Everyone with eyes knows its not firing. These idiots dont even know what a torwue wrench is for. They were torquing accessory fasteners. But didnt torque the cam journals. Or crank caps. They also didnt put oil on anything. I wouldn't look to them for any knowledge they do this only for money from youtube.
@@krotchlickmeugh627 probably wouldn't matter if they had torqued them. Their torque wrench is probably shot. It looked like they were using it to break bolts loose I stead of a breaker bar lol.
If the jets are clogged and they didn't clean and adjust the carbs, it will be misfiring. But there are also other 'issues', like valve clearance check that wasn't shown in the video. I see new pistons, new rings, but were the cylinders reglazed ? Or the valve seats re-cut and polished ?
They didn't show the state of the bore, the crank journals, the valve seats, I can't even tell if they stuck new big end bearings in. I'd like to know why what was wrong with it to begin with to understand what they did to 'fix' it. My guess is probably ruined bores from overheating after seeing the broken water pump in which case new rings and a black paintjob aren't going to solve your issues.
@kennethconnors53 - didn’t you know, there’s a whole army of people out there dumping and trashing motorcycles just so restorers like these can “find” them on their travels (normally followed by another chap with a camera just in case of such a “find” - how lucky is that?). Furthermore, none of these bikes have registered owners so ownership automatically transfers to the restorers.
I thought u were supposed to turn the engine crank with a wrench as rebuilding it? so it doesn't explode when you start it from the new grooves and lands in the cylinder walls? Or is he using the original internals?
Might wanna upgrade the regulator on this model of bike, mine blew not long ago just from added heated grips and led lights. Not sure what to upgrade too, or even if I can just use any old regulator like one from an r6 or something that can handle more electronics, but definitely put some thermal compound on it once you install it so it transfers heat to the frame better.

Hmm, bit of an unorthodox pattern for loosening cam bearings and head stays, ending up still fully torqued at one end of the head with all the other bolts loose is not really ideal, but anyway..
The engineering on these Honda engines are truly amazing, just like a fine handmade swiss watch...Damn Honda u scary :)

lots and lots and LOTS of rpms, it is the only way also look how tiny those little pistons are, they look like free samples of a real piston.
This is not a restoration. This is engine painting and assembly on dead spare parts. And that damn sealant, sealant everywhere. OMFG
Yes, I agree. Sealant everywhere, he even didn't tear off excess of sealant... And the old rusty coolant pump... Cylinders surfaces...
The people that don't know about engine rebuilding will look at this and think it's cool.. the few of us that know will cringe 😬

Yes.
Cylinder 3 was not firing either.
They also didnt torque anything important.
