How to Deck / Level Head Gasket Surfaces : Honda CB175/200, CB350, CB360, CB450, CB550, CB750

[@speedphreax]

Nobody told me this simple trick until, after many years, I figured it out myself when I was looking at the kitchen counter top when I was doing the dishes. Works great and saves a lot of money if the only option you have is to have it done by a machine shop.

I wish I saw this video before I buttoned up my CB360 top end. I discovered upon re-teardown that my head and cylinder were warped, which accounts for the oil leakage in the head gasket. I will be using this method to get them perfectly flat!

really enjoying the videos you guys have been doing lately, always great info, thanks!

Thank you. Great video. 👍

Excellent 👍😀

It's like the cheap version of a Starrett surface plate. Nice technique.

I picked up a 1 inch granite cutting board and had a friend throw it under a surface grinder. I can now cut cheese with a .0012" accuracy, though not even trying that after rubbing engine parts against it.

What does this do for cam timing? Not taking enough off to effect anything?

[@alishalchi1260]

Brendan my man, I love your videos, parts, and service! Can you please try to source transmission parts such as the detent wheel. It's absolutely impossible to find and these 450s are notorious for failing. Can't find one NOS. Guaranteed you will sell thousands

[@barretglasnapp6427]

what is the advantage to using gs850 pistons?

[@sloanchapman8847]

Hey Brendan, is it ok to do this to the valve cover and top side of the cylinder head or is it best to leave them alone? Cheers

I have a cb350 with a rebuilt motor and it’s leaking oil from where the head and cam case meet. I’ve torqued it a few times but it’s still leaking. Do you recommend this process, when doing the gasket change?

[@Common-motor]

This will help any machined surface where gaskets meet. On the gasket in question might try using a thin sealer like gasgacinch with a new gasket. Not a common gasket to leak, but anything is possible.

[@roygriep4004]

Just wondering if I would have to pull the motor to deck the cam housing and replace the gasket. Or can I remove the cam housing with the motor in the frame on a CB350. Thanks for your help!! ,

[@Jambi555]

@@roygriep4004 Unfortunately, as far as I can recall the motor needs to be removed from the frame to be disassembled. There's not enough space between the motor and the frame to be able to pull the top cam cover off of the eight rods, so you need to pull the motor.

Where do you find an oil dropper like that?

The original gaskets are asbestos, just keep that in the back of your mind while your working on these old bikes
