1981 GSX750 - cam chain

[phrode]

Do I need to split the engine to change the chain? It has only done 80.000 km, but there is a ratteling noise

[matt1100]

If it is the same as my 1100, yes. Unless you would gamble with a master link, most would not. Mine had a knock from the cam chain that went away after I rebuilt the tensioner. Cliff (bikecliff) has a tutorial on his site. Good luck

Before you go changing the chain measure it as per the manual. I bet it's fine and the problem lies elsewhere.

The tensioner guide, anyone know the site adress?

Have you measured the cam chain?

Unless your motor ran without oil for 200 miles the chain is fine.
(hint the bike would not run 200 miles without oil)

[phrode]

Thank you. Im going to check the tesioner :-)

New info and pictures

Well it is not -20 here so I have finally had a chance to work on the bike

I got the cam tensioner off, following http://www.bwringer.com/gs/camchaintens.html guide, but I cant get the knurled knob off the adjuster shaft. The guide is for the GS850, so i guess there is some diffrence.

Can anyone help?

You should be able to pull it straight out but you may have to give it a bit of a tug.

That tensioner is generic across the board. Are you stuck on Step 5 or Step 6 of his guide?

[phrode]

Im stuck on step 6. Tried pulling, but it wont come off. Can I heat it up?

[tkent02]

Maybe someone used locktite or some kind of glue on it.

[Guest]

Too much heat will destroy the spring. Heat gun may be OK but nothing with a flame.

[phrode]

I got off :-) My kid's little hammer, and a some careful work did the trick.
