Rattle on start up in cold weather when bike has been stood for a while?

[jeff evs]

The first time I had this is when the bike was laid up for around a month and the temperature around zero degrees.
On start up there was a rattle which lasted for around a minute then disappeared.
Anyone else had this issue or heard of it?
I've seen a couple of posts on other sites saying they have had this problem since the first service.
Could it be an oil viscosity issue?
Any help would be welcome, thanks
Jeff

Should be tha cam chain tensioner discharging oil during long stops

I get the same clattering sound anytime i start it when its cold out (<40F) and the engine is cold. It doesn't matter if it sat for 10 hr or a week. It goes away soon as there is a little heat in the engine. I thought the sound was coming from the clutch, but its really hard to say. I would love to know what the cause of the sound is. So far, I've chalked it up to MG character.

If it's a tinny sound, mine does it too. Sounds a little like the exhaust shields resonating at a different frequency on start up. Hope that's it, I can ignore that and it won't cost anything

If the bike has hydraulic cam chain tensioners that could be the source. Common on 1100 and 1150 BMW boxer engines on the left side. Fix was to replace the left side tensioner with the 1200 version.

Even the 1200 version BMW needed upgrading. Had to do it to my 2004 R1200CLC. Quieted it down a lot.

Yes, it is a tinny sound and I did check the exhaust shields but they were all good.

Thanks very much for your replies .
Cam chain tensioner does sound like it could be the problem.
Will take it to the dealer which unfortunately is a five hour round trip since my "local" Guzzi dealership ceased trading.
Thanks again for the input.
If I get a decent video/recording I'll post it up.

The hex head 1200s had the good tensioner. They came out in 2006 or 2007 I think

I'm on my second engine. First engine was ticking at idle and coming from a Cali 1400 I did not really notice till a few weeks had passed. I took the bike in and they replace the hydraulic tensioners with no affect. Bike was only loud at idle and when cold, at about 140 F it quieted down and in all other respects was fine. In the meantime, I had a bad crash on the Cali and was out of the riding business for about eight months so there was no time pressure on the replacement which took about two months. Got the bike back changed the oil and filter after 600 miles and it's been great...
