    Front Fork Oil, Seals and well ... a stupid question :) Cam Chain Tensioner ..

    Ok - lie to me if necessary ...

    I have a little bit of weeping (from my third marriage) with the front forks. Will try to slide something safe and thin in between the fork seal and the fork tube ... Regardless, I feel like the fork seals should be replaced with 24k miles (2016 bike).


    My dopey question relates to ... Can I add fork fluid without disassembly whilst on my unexpected road trip this week?

    Any feedback on which Fork Seals I should buy here in the USA?   


    Ted's Beemer Suspension shop? Other?

    Unable to get into the service shop for a couple weeks at least, and see just minimal oil on the fork ... no drips or puddles


    Cam-Chain Tensioner ... Mine is just starting to make a little noise, and I'm wondering (Naively) if this is a difficult or expansive (not expensive, but labor intensive) repair ... Valve check completed at 16k miles


    Thanks much in advance ... I'll hang up and listen now.


    Smiles, Scott

    Those are the seals I have used, and are pretty well priced as well. Your forks are going to have to be really squirting out oil for them to need you to top them up on a trip. I guess you could unscrew the right fork cap(providing there is no weight on the forks and top it offf a little, the left side(active) is a little more problematic because of the wiring.

    As far as cam chains go, if you want to replace the cam chain, then everything has to come off(ala valve check) as well as the 2 camshafts. You will also need the BMW special tool to set the timing after. Other options are the BMW 'Silver' cam chain tensioner, or a manual cam chain tensioner ((APE, etc).

    With a little noise I reckon it's just the good old black hydraulic tensioner getting a bit sticky. Get a manual tensioner and you're done. I've done mine now and all noise is gone, my OEM black tensioner was not moving too freely and I had a fair bit of rattle before going manual. All the manual options will work, up to you how much you want to spend.
