Exhausts and Engine » Cam timing check

I've just checked the cam timing on my 40,000 mile 2015 1200. I borrowed all the tools required from the BMW Club UK.

Both sides were out. The go/no go gauge is a very good fit and it wouldn't even try to go onto both cams.

I reset both sides with the cam chain tensioning tool in place, this simulates the spring force on the tensioner plus the hydraulic force when the engine is running.

On replacing the tensioning tool with the original tensioner the go/no go gauge wouldn't fit. So the tensioning tool does make a difference.

I also checked the valve clearances at just over 3 hours since the engine was hot. They were all in spec. I'll check again in a couple of hours and report back on any changes.

I'm out on the bike tomorrow and I'll be interested to see how she runs. New plugs and air filter are being fitted as well as oils and filter.

I am pleased that the BMW club were able to help you.
People think it's very 'pipe and slippers' but I see the members as no different to contributors to this forum. Very friendly and willing to help if they can.
The quality of the magazine varies from month to month but has the occasional good article and also offers discounts on products from a variety of suppliers.

Was the club able to provide all the tools required to do the cam adjustment and what was the hire charge?

There is a £50 deposit and you need to pay return postage. I'm also posting some of the items to another member.

I bought a 3/8 16mm torque adapter but the club are buying one too.

Included was an ISO of the BMW manual

2 things, having checked my valve clearances at 3 1/2 hours from a hot engine and then 7, there was no change in clearances.

I've been out today. I don't believe that the new air filter and plugs would have made a discernible difference. Both the old plugs and air filter were far from being desperate for a change.

Initially the bike felt a little crisper. Later on, riding familiar roads at 60+ mph I found myself comfortably holding 3rd gear where before I'd have felt inclined to engage 4th. So it's smoother as the rev's rise of that I'm sure. I still get a familiar tingle through the seat though.

Is that required at all? Definitely not part of maintenance schedule. Did you find the cam chain tension off spec?

See post no 1 Cam timing check "Both sides were out. The go/no go gauge is a very good fit and it wouldn't even try to go onto both cams. "

Sanemancurred,

When you applied the cam chain tension tool did it take a lot of force to get it click 3 times? Did you use your fingers to thread the tensioner in or use a small wrench on the nut at the bottom of the tool?

Duckbubbles,

Thanks for the reply. Appreciate it. I was having trouble getting the cam tension tool to click and thought I would ask others about it before I broke something.

Thanks again.
