Hi Guys,
I am trying to assist a fellow UK BMW club member with his K1100 who lives in Scotland, at least a 4 hour ride from me.
He recently bought the bike which has a low recorded mileage of 30k miles. He considers this is genuine as various bolts, while having surface corrosion, do not appear to have been rounded off.
While he is not new to the K series, he already has a K1, this is the first time he has had an 1100, so is checking it through, and fettling where necessary.
So why the posting?
He checked the valve clearances, and the bike requires two inlet buckets to be replaced, the exhausts are within spec. So a straight forward job to do, given that I have sent him the special tools to do the job. 11-3-700 camshaft lock tool, 11-2-640 Cam chain tensioner tool, 00-2-580 DTI holder/extension, and a DTI. He also has 12-3-650 the BMW static ignition tester, and 12-3-651 adapter cable for the K series.
The problem is that with the engine at TDC on #1 cylinder, the camshaft lock tool cannot be inserted in to the slots on the camshafts because one of them is about 1 degree out of alignment.
We discussed the possibility of a stretched cam chain, would this produce such an error? Or maybe a sticking/worn cam chain tensioner? Bearing in mind the low mileage I would have thought neither of these.
I have asked him to hold off stripping the chain and adjuster just at the moment, but he is quite happy to do that and measure it against a new chain if required.
I did a forum search and only found one set of photos showing a problem where the triangular cut outs in the sprockets where misaligned. I think that was an extremely worn chain.
Any suggestions.
Thanks in anticipation.
