Auto decomp spring on 2002 FE650

Hello
Took the engine out of my FE650 for the first time (for me) and having a poke around. The link below is a video of the the auto decomp, should the spring be firmer than this?
Also checked the cam chain tensioner and it was fully extended to the end "click". So a new cam chain I guess? Anything else I could check while I'm in there?

Cheers lads

Great videos, very helpful!
But when Iím changing the cam chain what else should I be looking at while I have the engine out?
Iím looking at your website Taffy for a new headgasket, new cam chain and auto decomp spring. I already have the black plastic cam pusher thing, so that should be good?
I couldnít find a rocker cover gasket (is it called that on motorcycles) on your site, do you have one?
Donít have any issues with the valves but would it be worth changing to the double spring valve springs? Got single spring at the moment.

Cheers!

But when I’m changing the cam chain what else should I be looking at while I have the engine out?
A; well I'd put sealed cam bearings in. I'd change the cam to a road & track based cam, remove the stopper on the steel cam sprocket (usually an M5 allen bolt and nyloc nut), your inlets will be tuliped and rubbish, the 4 valve seats won't be square and so the valves won't be sealing

I’m looking at your website Taffy for a new headgasket, new cam chain and auto decomp spring. I already have the black plastic cam pusher thing, so that should be good?
that pusher thing? a Cam chain tensioner blade or CCTB. head gasket = two words.
we always split words like kick start and side stand. ADC and modified spring. if that 650 is on the road = change the cam

I couldn’t find a rocker cover gasket (is it called that on motorcycles) on your site, do you have one?
that is because the rocker cover to head is a silicon seal no gasket job. Use wurth sabesto RTV sealant and get the black

Don’t have any issues with the valves but would it be worth changing to the double spring valve springs? Got single spring at the moment.
of course! its a 100% must. and you do have troubles with your valves, its just that your standards are lower than mine. Your valves are only seating for 20% of the entire 360 degrees. Every single engine we have to have the valves faced and the seats cut and never, not once do any of you (plural) or my customers have them done. You just can't see it.

I do a FB video of the ten things you need to do to make a husaberg start and it was aimed fairly and squarely at the 2002 650 owner.
