    Gen 2 Valve Clearance Check? Has anyone done it yet?

    I know there are topics on this, I just wasn't sure if I should re-ignite them or just start new Topic. Lets just start new Topic.

    So, I'm sure there should be plenty of people with Gen2 XRs that are way above it's 18k miles and are due for their first major service.

    My 20 XR has 20k miles on it and tuned, seems to run fine, no abnormal sounds that I can hear.

    Has anyone done Valve Clearance Check?
    Did you do it yourself?
    Should it be done, or wait til the next major service?

    I'm about to replace my spark plugs, should I open it up and check the valve clearance while I'm at it. I know I will need o-rings and cylinder head seal set, that will be around $300 all together.

    What are your opinions?

    My bike is still under warranty, so I took it to the BMW dealer to get the 30k km service done.
    As expected, all valves were within spec, no adjustment needed. And that is usually the case with these bikes. But please be aware that this first 30k km’s check is the most important one, because biggest changes in clearances happen as the engine breaks in from new. Later checks (60k, 90k) will show much smaller changes.
    They reused my head cover gaskets. Technician said that according to BMW they should be replaced only if they are found damaged or leaking during the service.
    They do, however, replace couple of bolts and small gaskets at the crank bolt cover and crank position sensor, since they are removed during the service, in order to rotate the engine and insert the locking tool

    Hmmm, seems like it would be wise idea to do it, since I'm going to be within reach and everything will be right there for me while I do spark plug change.

    This is the video on new Gen 2 engine, I found it on youtube on how to do it and what you need. It's in Russian language only tho if anyone is interested.

    No way you need all that just for a clearance check... 150 for a valve cover gasket? joke... 22 per bolt? also joke, I wouldn't bother, a fresh gasket like that seldom needs replacing, just be careful, and even if it's a bit leaky crusty, nothing a dab of silicone won't keep in check. at that cost might aswell take it to BMW...

    I might just need the 6 bolts, they say they are one time use, other o-rings and gasket should be fine.

    From what I read and found out, this service is about $1000-$1200 at the dealer. I do all my work myself, I'm pretty good at it. Last time I took it to the dealers, they were replacing my coolant\oil pump, they screwed up so bad that I don't want to go back there anymore. Oil was leaking, several cover bolts were missing, coolant was below minimum and they scratched my fearing, which than they said the scratch was there already. I don't know about you, but no dealers for me man.

    A BMW specialist then. I didnt replace anything on my gen 1 and afaik it uses the same style of bolts etc. And for sure none of that cost like 300 bucks. Up to you really, they say things for a reason, but common convention for certain things like replacing valve cover gaskets everytime makes no sense whereas, other things like performing routine brake cleaning which is arguably a billion times more important is severely overlooked.

    Unless the bolts are aluminium, and they are torqued to yield, or they have crush washers on them (which is what i recall they may have, but then again you can replace those separately) i wouldn't bother. I see no engineering reason to.

    Then even if you don't replace things like your valve cover gasket, a dab of silicone sealant IS a correct solution, not a macgyver or bodge job, just a different solution to factory. They use rtv silicone elsewhere anyway. No different to it being applied on the valve cover vs the timing chain cover.... anyway, just an example, but if the problem is a leaky bolt, im sure you can find alternatives to that too.

    Just my 2 cents. I'm sure I'll promptly be told I'm stupid and on the other hand if you're not worried about spending that extra $$ for peace of mind, then by all means, I'm just a tight arse.

    You're completely good man. I take in everything you all are saying, than I'll make my decision. This is why I created this topic to take in opinions. I really do appreciate it on everything you have said.  :152: :821:

    I did the valve over a year ago now and just follow the service manual there was nothing really difficult about it all my valves were in spec and I carefully reassemble in reverse order I have done other motorcycles that I had the hardest being a concourse 1400 where you have to work through a very small opening and remove the cams to replace shim under bucket I found this easier but did not have to remove the cams as they were in spec

    What were your specs? Did you record them on the sheet? I would like to compare mine to your just to see if I'm doing it right. Thx
