Cam/timing chain + valvetrain inspection

Hey folks! After removing the exhaust to change the bearing, seals and o-rings in the clutch cover/H20 pump i noticed the top end gasket was sweaty/wet so i thought id change that as well before it starts to leak..

So I need to break the timing chain and rivet it back together to get the head off, but would you suggest to change the entire chain or just a new rivet link? Also what specific parts of the valve train is to be checked since it's off the bike?

To clarify, it's a 2008 fe450 with 49.8 hours as of now, has been rode by me after the 32h mark. Chain is not off yet but the tensioner was 14 clicks out of 17 max, and has little play on the cam sprocket even with the tensioner off.

I know there is a lot of threads about this but nothing that I could conclude on anise most of them are already having more issues and I've had non but a small leak from weep hole.. probably bc of the long time period before me that it was just standing in a garage not being ridden.

Thanks, I really appreciate all help from experienced Berg riders!

Adding that I have found an industrial type 3/8 roller chain that I believe should be the same or at least function the same as oem if not better! Thanks!

Since you have such low hours, if it were me, I would just re-torque the cylinder head bolts, clean the area well and see if that will take care of it. Again due to the low hours I would keep the stock timing chain until you accumulate around 100-150 hours. There is nothing wrong with the stock chain.

The weep hole will always be a point of contention. If its just a very small dribble I consider that normal.

It can't hurt to refresh the water pump seal every 50 hours or so for peace of mind.

Thats what i thought as well with the gasket/seals just dried out since the bike was on a stand collecting dust the last couple of years before I bought it in 2018 from a friend of mine. It was just a minor leak of oil from wheep hole too.

I got the head gasket but all I would need is a new link for the chain if I do end up splitting the chain, right?

Thanks! I'll get back during the week with the results.

Hey!
So I ended up buying a "cheap" chain tool kit that is for drive chains to try and remove and rivet the new link on the cam chain. But I ended up breaking my foot instead of the cam chain... later that same day so haven't really done much but eyeball my bike wanting to ride again in the beautiful Swedish summer days.. Returned the unused tool as well but does anyone have a good way to remove a link without it or know a reasonable priced chaintool that works? And I still that new link to repclade the once pressed out, but I can't seem to find anywhere now..

yeh! a 4" grinderette!

but don't put a new link on an old chain?

there's an old saying about it that escapes me right now, something about 'the weakest link'.................
