Thanks for all that, yes I had ground the shims to suit but have now replaced them with new ones. I didn't realise they were hardened.

I have the timing done, still looks a small bit out, could this be from chain wear? When should the chain be replaced? Theres 60K on this bike.

Thanks

The chain should be ok until the tensioner runs out of adjustment. I've got 67,000 miles on mine and there's still plenty of room on the adjuster.

Timing chain for a 900 here. That may get you started. I don't know the differences (if any) from a 3VD to a 900.

That's weird, the photos are still showing up on Facebook so they must have changed their storage system so the links no longer work.

Try this https://www.facebook...mp;l=4d458f092a and I'll see if I can relink the photos in the original post

I've relinked both the first post with the checks and the later one with changing the shims, so hopefully they should work ok. Until FB change their bloody system again. Might be worth me putting them on my webspace I suppose

First of all, I have to say I'm so thankful for carpe-tdm. I've learned a lot, and currently trying to do all the servicing and fettling on my own 900.

Now I checked clearance, and swapped around almost all of the shims. I had a couple of 0.12-13 on intake and two 0.22 on exhaust. I opened them up to 0.16-17 and 0.26-28. I left the 0.16 as is in intake, and the 0.24 on exhaust. I think I did everything according to the manual, but the valves are now really loud. I mean, REALLY loud. I didn't bother with adding moly grease under the buckets. Just used a dash normal multi grease. And I forgot to splash some oil over the cams before I closed the lid. Are all engines this loud after a shim change (clearance opened up so much) Should I drain it and open again? No problems with the cam chain tensioner btw.

Just wondering if you pushed the shims in fully, they are a tight fit. I used to swap the shims then replace the bucket and give them a firm tap with a small hammer to make sure they were fully bedded in. 

 

You might find that they bed in over a few days and make less noise.

 

After you fitted the shims, did you turn the engine over manually and then measure the valve clearances again ?  Or did you just fit them ?

I made sure they were seated fully. A really tight fit. And I turned the engine around a couple of times. I have a sneaking suspicion I forgot to tighten the cam sprocket bolts. Had to redo the timing following day, due to too much cake/beer at first attempt. Think I'll pop it open anyway. No sweat now that I know the drill.

You can now put the cam shaft back on (remember the lobes on the left cylinder face away from each other) and torque it up correctly (10Nm), though I leave the guard that goes over the chain off until I’ve got the timing set. The front side of the chain will be tight, but the rear will be loose because the tensioner’s not in. Using screwdrivers or allen keys as levers though the holes in the middle of the cam shaft rotate the shafts towards each other to get the timing marks aligned and the front side of the chain is tight. You’ll find you can easily turn the cam the other way a bit and skip the chain on a tooth if it’s not quite right. Once it’s in place put the tensioner back in, then the tensioner spring, and check the timing again.

I've seen a few complaints on how to keep it all timed while getting sprockets fastened - there is a tendency of cam chain skipping a few teeth on the intake sprocket. I found a solution to this, maybe one could do this before removing camshaft sprockets ?

It appears all my pictures have buggered off again, bloody facebook.  I've bunged a link to the album in the first post for now but it would make sense if I sorted this out as it appears to be useful still.  Does the gallery on here now work to host the pictures?
