    Hi All.
    I'd like you guys to listen to my California engine but how do I post a video?
    It sounds a bit knocky at the top end to me but I need some opinions.
    It's a 2001 so has locknut tappets rather than hydraulic
    Thanks folks

    Quick edit
    I uploaded it to my YouTube channel.

    I'd say you're quite correct ! Are to we assume you've already checked the valve clearance ? Peter

    Ah Ha
    Done it.
    By the way I just bought it.
    It is in my garage so there is some reverberation but is this too clattery.
    Do I need to investigate?
    Thanks guys
    According to the service log the valves were done a couple of hundred miles ago
    So I need to check them

    Yes there is a little valve noise but I wouldn't consider it excessive. Clearance is 0.004 inch for the intake, and 0.006 inch for the exhaust. Be sure to halve each cylinder on the compression stroke at TDC. I find it easier to set the right then the left. You don't have to rotate the engine much to get to the correct TDC on the left side if you do it this way.

    What John said. I have the same year with 90,000 and had a 1998 with 80,000 miles. Yours does sound a bit too loud to me compared to either of mine. Could they be set at 6&8? Just to make sure it might be wise to actually pull out the rocker shafts and make sure the oil hole through it is clear. I once had a 1990 that had a big long curl from the original drilling of it blocking the oilflow. If you do I usually (wright or wrong) rotate the shaft 180 degrees because there is always wear.

    Per above, I would remove and inspect the rocker arms for wear. Some I have seen have had excessive wear and needed to be reground and/or replaced.

    Thanks guys.
    I should add that the bike is at 19,000 miles and the ticking is coming from both sides and not just the right as in my video.
    I'm hoping maybe someone didn't set the valve clearances correctly which I'll be checking on tomorrow.
    Better too loose than too tight I suppose.
    Would the grade of oil make a difference?
    It was changed recently but in the invoice they didn't specify what's gone in.
    Is synthetic or mineral preferred for these engines?

    Run full synthetic. It is worth the extra money.

    Interesting.
    I've come from the world of BMW where the general advice is to steer clear of synthetic in the older airhead and oil head twins.

    I started running the Shell Rotella T6 5/40 about ten years ago in almost all the bikes. $23. a gallon at Wally world and as much as twice that other places. I know John prefers Mobil 1 15/50 and that would be my second choice.
    We should have asked but were they always that noisy? 19,000 really isn't broken in yet.

    My wife has BMWs, both airhead and oil head. I run full synthetic in them with no issues. Sounds like you are hanging around with a bunch of folks that don't like new things.

    I speak FLUENT BMW and have owned so many of them since my first one at 18 years old, that I have lost count.

    I agree with John.

    In all my years associated with BMW, I have never experienced a single problem with synthetic oil in any BMW motorcycle engine, R, K, or F series.

    Sorry but the "general advice" you have heard is absolutely dead wrong.

    I used to ride with a group of BMW riders in San Diego that called themselves "Airheads". Simple by Choice was their moto, and despised the later "Oilhead" BMW motorcycles with their update designs. Part of me agreed with their philosophy, but couldn't understand why they preferred points over electronic ignition. Unfortunately, I've lost contact over the years.

    BTW, I endorse full synthetic oil everywhere! It is rocket science.

    Yeah I'm sadly familiar with these stalwarts.
    But I have heard that fully synthetic is very good at getting through seals on older engines.

    I remember this when full synthetic first came available. Never affected me. Old wife's tale?
