Smoking from cold

Duaneage,
I was referring to an earlier post by someone else. They removed/replaced the camshaft for every valve - at least that's how I read it.
 
if you referring to valve shim clearances you need the tappet drepressor tool. this allows you to swap shims without removing the cams
 
so duaneage
you say leave alone because compresion ok (leave barrels on)

so do you not think its a good or not to take head off and try and sort out valve guides/stem seals.because it will keep on smoking if i don't do any thing
and i hate it smoking and guys (with there xjrs ,triumph triples ) says well it is 24 yrs old and at least she's still going. aaarrgggggg

o i wish money was no problem a

Your compression looks good, the rings are probably fine and the valves are probably OK as well.

If the smoke gets in your eyes remove the head and change the valve guide seals. They are pretty easy to do with the right spring compressor, look around for one that can get down between the buckets and compress the spring. I would wait untill you the head is off before getting a tool to be sure it will work properly.

You can test the valves with the head off the engine this way:

Put the head on a bench upside down with the cams REMOVED so all valves are closed.

Use a level to make sure the head is level on the bench. I shim a head with wood blocks and clamp it to keep it still.

Pour kerosene or diesel onto each combustion chamber and wait a few minutes. If no fuel leaks past ( or at least not a lot) then the valves are good to go and no attention is warranted.
 
You use a tappet depressor tool to press the buckets down and then pop out the shim. No need to remove the camshafts.

Many KZ Kawasakis used shim UNDER bucket valves, requiring camshaft removal, but GS models use shim OVER bucket valves -- the cam lobe bears directly against the shim when the camshaft rotates.

Some later 16 valve gs models used screw and locknut adjusters -- no shims involved.

The valve adjustment procedure is very clearly documented in both the Haynes and Clymer manuals, so you really ought to get one.

If you're in the US, the tappet depressor tool can be found here:

The tools are on this page (scroll down to the shim tools):
http://crc2onlinecatalog.com/tools.htm

CRC2 also has the shims for $5 each.
 
Hi folks
me again have just re assembled the head and amazingly all of the valve clearences were well within tolerance even with a slight lapping with fine paste so i was well pleased, but my next question is this, as i had to remove the carbs i thought i would give them the once over so i drained and removed the float bowls (removed a generous dollop of dog muck from the bowls)but noticed next to the main jet another jet which had a sort of rubber bung stuffed into it all but one were fine the last one had perished and now doesnt exist as it has fell to pieces,What is it for and can i get a replacement/alternative
cheers all
Graham
 
sorry folks forgot to tell you they are mikuni carbs with the flat tops
 
Hi Graham,
I think I might have some in my box of carb parts let me look when I get home from work. If I do I will mail them to you, just pm me with your address.

HI GARY

IS YOURS UP AND RUNNING YET
does it still smoke.did you just replace valve stem seals

mines stripped down .i think inlets side fine
exhaust valve stems measure 6.94 to 6.96 so that seams ok
guides as i said before not so easy to measure
1st a 7mm drill fits easy (max tolerence in book 7.10)
so i thought if i could force something down hole then measure it
so what ithought, tried carrot and blue tack but not sure if accurate got reading from same guide 7.22 to 7.30 if these are right ive got to much slack

yes i know it sounds maaaad i'll try any thing maybe a spud next
unless you know different

so if i do change ,looking in haynes manual it states put head in oven 150c then drift them out ..has any one done this? did it work whats it like getting new ones in .


do they need reaming (why ream :?: )
