Hello and thank you for adding me to the forum and I want to give a shout out to the moderator who is an excellent Guzzi resource and friend! I have a couple of questions...

#1: I changed my oil & filter and cleaned the "sludge" out of the pan and while I was in there I found many fingertip-sized metal particles (draws to a magnet)...ugh...the bike is running fine before and after the oil change but I am hearing a loud ticking now. How can I track down where those particles came from? (see attached pics)

#2: I want to adjust the valves and I thought that I read INTAKE 0.004 and EXHAUST 0.006 is universal, just double-checking. Also, wondering while I have the covers off what else I should do or look for? Should I re-torque the heads as well?

I don't have a manual so where can I find some detailed information for working on my stone? Thanks for any information that you can provide and have a great day!

Gigi,

You did a nice job cleaning it up. How many miles are on the bike now? Those particles could be from a lifter or cam since they are magnetic. Yes the intake is 0.004 inch and the exhaust is 0.006 inch. If any of the gaps at the rocker are much larger than the specified clearance it would point to a lifter/cam fault. That would require pulling the cylinder on the side where the lifter failure occurred to replace the lifter and inspect the cam. Let us know if the ticking goes away after the adjustment. If the ticking doesn't go away it could be cam chain.

Thanks John! I knew you would offer some ideas and help with the situation, unlike the previous comment...I'll be sure to inspect the lifter and cam when I open it up tomorrow! I have over 22k on the bike, which is not a lot, do you have a link that you suggest for purchasing a new lifter? Take care and have a great day!

Do you have the tools needed to include a good torque wrench? You can look at the cam with the sump off. If you see scoring, that is a good indication of the failure. It may require removing both cylinders to identify the faulty lifter(s). Then you need to open the timing chest to replace the cam if damaged. You need an extra deep socket to get to the crankshaft nut. I had one made locally from two deep impact sockets. That requires removing the timing chain to replace the cam. At which time on assembly you can put in a better cam chain tension than what came from the factory. It may be a bit more than you want to tackle. BTW, this can all be done with the engine still in the frame.
 
Hi,

I too have a 2001 80th Anniversary Stone which I have just serviced.
I was told by Todd that the Stone wasn't available in the USA before 2002, so are you sure that it is a 2001 build date from the VIN#?
I ask this because it is right on the change point when adjustable lifters were replaced with hydraulic lifters. As you may know, there was a big problem following this change with lifter/camshaft hardening failure. This resulted in a large recall of bikes for changing camshafts etc.
The date of first registration on your paperwork may not be the same as its true year of manufacture, My Stone is 2001 but was not registered for the road by the supplying dealer until March 2004!
I suggest that you remove a rocker cover and see whether you have adjusters on the rocker arms as a starting point. There is a thread in the "stickies" at the top of the first page on the cam lifter recall with photos of both adjustable and hydraulic rocker arms for identification purposes.
Hope this helps!

Thanks for the info! I never heard this before but will check it out...

Thanks John! Did you see the next post regarding if my bike is really an '01?

It is not a hydo motor. I have adjusted the valves on the bike in question. I think hydo engines first appeared in the US in 2003.

You can check the 10th digit of the VIN# for the year of manufacture. Mine is a 1 indicating the 2001 model year. It also came with a Moto Guzzi 80th Anniversary badge on the fuel tank.

It seems that this is academic now, as it appears that John knows this particular bike and has actually adjusted the valve clearances.

I can only wish you the best of luck in resolving the problem!

Yes, thank you and my bike has the 80th Anniversary badge on the fuel tank, and a couple of years back John did adjust my valves so I think it is safe to say it is 2001, thanks again for your information!
 
Two points.

First, while a long shot, it's lots simpler than chasing other causes of "ticking."

I pooh-poohed a friend's suggestion that a loose header flange caused ticking. He was right; I was stooopid. That was it. Might not be your issue, but worth a look.

Second, I am an untalented wrench who loves tinkering and, as a result, have a bin of "leftover" parts. ;)

That said, I think you were unnecessarily hard on kiwi dave's "just ride it" suggestion; there's lots to be said for riding instead of fiddling. I have 102K on my EV, so I have ridden it, but would have 200K on it (and more on the rest of my moto-harem) if I had ridden more and worried and wrenched less. These days -- especially at my age :cry: -- I try to save serious moto-work for a tropical depression settling in over the Moto Grappa for a few days.

Good luck finding the tick.

1921!

Over at a competing forum, there's an example of someone finding a unmolested valve adjusting screw in their sump. These things happen, during assembly at the factory, or perhaps by a previous owner or dealer.

Makes this find miniscule in comparison,

That can happen, but I did a complete service on this bike a couple years ago and no metal was in the pan. As an example many years ago I found a piece of a lock washer in the pan of my MkV. One of the lock washers on a bolt behind the timing cover failed and it found its way to the pan.
