I went to the sight you had suggested and they were all out but had a "similar" bolt they said.... Wrong part. I called 3 more spots and couldn't find it. Not sure of the dimensions either.
Part is-BOLT 90021-469-000

For sure was going to flush the oil. Pretty black.

Looks like pickings are slim on eBay, but that part you have doesn't look right. You may be better off having something machined if you can find the specs

That's funny timing. I just came across the same part. Weird my searches didn't come up with that, when I searched for cb750 bolt it popped right up.
$13 for the bolt and $23 to ship and 2 weeks to get here. Hope it's faster, I'm chomping at the bit to ride!!!

Sucks that it's that expensive, really makes you shake your head when parts like that are just 'missing'

Just found this, sorry. You seem to have the bolt sorted now, but that thread is cactus. It's a common problem with these motors as the bolt is over-tightened and the thread gets stripped. A pain in the arse to repair considering it's size. You'll have to drill it out for a new helicoil. Problem will be getting access with the motor in the frame. I've only done them when the motors are out, but guys have done them insitu. Just gotta watch you catch all the swarf.

My guess would be the PO couldn't be fagged to do it properly because it's such a pain.

Bikeboy, funny you mention that. I finally got the bolt that I was waiting for and the PO had stripped it out and the bolt wouldn't fit. I work with numerous parts and found one that got in the hole. I have no idea if it actually puts tension on the camshaft chain but it's running for now. I think that I'm just praying that it keeps it going.

How else can I repair it?

Same bolt was used in all the DOHC motors, from the 750 to the CBX. Oddly, the -469- part of your code is for the '80 CBX, but they usually use the model the part was first used on, which was probably a '79 CBX (422)? Anyway, looks like you're sorted ;-)

Still would rather use stock bolts. I'll check out that 422 bolt see if perhaps it fits better.

422 bolts didn't fit, too small so what I had in there will have to do.

Today's project was that I was going to take off and replace my air compression shocks and replace with coil springs. Mainly for looks not for comfort.

Anything I should be forewarned of anything?
