Post by ernest rudshtein » Tue Jan 02, 2018 2:06 am



im in need of some info you guys
im in the middle of a head gasket job my first time doing that
ive got all the parts off ( heads cams belts and rockers) cleaned all and orderd all new oem parts.
now im facing reassembly.
can anyone please post a link on the right way to reassamble all the parts? a quick litteral guidence is good as well.
i dont wanna do anything wrong regarding the cams/rockers/timming belts sync.
also, should i spray cooper sealent on the gasket, or OEM gasket already has sealent in it?
tnx for any reply

take the heads to a machine shop, tell them what you are doing.

ask them to resurface them "Just enough" to make sure they are totally flat.

they will know what you want, it is a common practice that SHOULD ALWAYS be done when putting new gaskets on.

if you don't, you risk having a water leak.... and that is no fun.

another question
the gasket i removed was an after market one- failled horribly. how can i check if the head was flatend in the past? if so, will it change the valve clearance? if ill take it to a machineshop to be flatend once more?
dont wanna end up loosing compression

regards

If you have a steel office ruler, lay it across the head.

If there is any daylight showing you will know that it needs to see a machinist.

or, just ask a machinist to lightly true it up, they do that all the time.
what they take off is extremely small.

when a head is flattened (we call it skimmed) they just remove a small amount of metal from the cylinder head where the head gasket sits, this has NO effect on valve clearances, but you obviously need to check the clearances once you have the engine back together. Just set them to the Honda recommended clearances.

Great stuff if used properly.

my dad taught me how to use it back in 1958....
but at the time, the brand name was KopperKote or something like that.

K&W owns it now.

Amazon has it, should be able to find it in any good auto supply store.

If you are using an OEM headgasket DO NOT use sealer on it. Can't say if it would help an aftermarket gasket.

If you have a flat pane of glass, you can set it on a table, coat it in valve grinding compound, and slide the flat surface of the head in a figure 8 pattern over the top of it. This will true up the surface, but it takes time and effort, and you have to be sure to get every tiny remnant of grinding compound out of it afterwards. I'd likely just have a machinist do it in a few seconds.

Or sandpaper instead of lapping compound.

Do remember that after doing this, the glass will not be usable for a window, so don't use your wifes favorite glass top coffee table to do this!! :lol:

gary seems u have done it before?! still married i hope :)
thank you wingadmin.
so i have places the heads, cams and cam holders, had one bolt snap inside and one that needed a new thread. did valve adjustment, new timming belts, fresh castrol 10/40 oil + oil filter and 95 gas, new-no silicate coolant, replaced both CDI( the PO cdi's where complitly melted) , checked coil resistance (3.2 ohm). after all been said and done i finally fired her up. sounded like a stubby bob 1957 truck on 1 cylinder.
so: the bike have set for 1 month while i was working on it- i was expecting a hard start.after she wormed up- she sounded alot better.
before i do a carburator adjustment- i wanna ask (and a bit afraid to ask ) i had the starter slipping a few times on first start ( have to say its around 55f outside)
so to finish the job- how can i save the starter clutch without pulling the engine out...?ATF oil? engine flush?
thanks to all repliers

The bike was built for 87 octane, doesn't need higher. Starter clutch is very common. One common fix is to drain off some oil about a pint more or less and put in Marvel Mystery oil, run it about 100-200 miles, and then change oil. This usually fixes it but not always. I've owned GL1100's and they all did it in cold weather. Then balance carbs.
