My 1200 twin engine is coming up to 40k miles so am planning on doing it's second engine service. The service schedule in my owners manual has an item that just says 'camshaft timing' but I see not mention of this in the routine servicing chapter of the Haynes manual, so am wondering how to do this? From what I can see, the only timing adjustment is in rotating the sprocket on the camshaft and aligning this correctly in mentioned in the chapter about taking engine apart. This involves putting a locking pin into the bottom end gubbins and the hole for that is hidden behind the alternator cover. I'm guessing this is what I'll need to do, but am reluctant to remove the alternator cover as I had a leak from there not long after I got the bike, and it seems very fiddly to get off and on, with the cables and grommet, and there's no gasket for sealing from what I can determine. There are a few videos of youtube of people doing valve clearance checks on these engines, and they comment that you don't need to take alternator cover off like Triumph say. What I'm guessing is that they aren't bothering to check camshaft timing on their services, just the clearances.
