    Need some help to remove the throttle body for cleaning

    Hello from VN,

    I am planning to remove the throttle body (CB1k 2015) for cleaning after 12.000 km ODO, so need some help here if anyone can share few photos from the Workshop Manual for the process : remove and re-assembly the throttle body. Will very appreciate!

    dude, that's getting waaaay deep into the guts of the bike. essentially you need the entire fuel system chapter of the shop manual, and as you may be aware protocol does not allow sharing of that manual.

    however, if you can work your way in, you probably can work your way back out too. here are some relevant sketches that should help...

    good luck!

    WOW. Lots of information in the above post.

    Your throttle body, at 12,000 km, should be still as clean as new.---

    ... and I had exactly the same reaction. unless it has gotten contaminated somehow, there's NO WAY the throttle bodies need cleaning at 12,000 kms... or, in fact, ever!

    agreed, leave it alone

    the price of a throttle body should be enough to make someone leave it be

    I must agree. I pulled my TBs on my old 2002 F4i with 37k miles for a manual CCT install and they weren't even dirty at all. Unless you ran no air filter at all, I think its impossible for them to need cleaned.

    If the bike runs good and you’re just doing this for routine maintenance I have to agree with others please just leave it alone and ride the bike they should not be dirty at all. Just my two cents.

    that does not look good... at all... but hopefully the filter is keeping most of those rocks out?

    however most crap that gets through filter should get stuck in the injectors and fuel rails, since the injectors are downstream of the throttle blades. rest of TB should be fine

    only a couple of bolts will get the fuel rail loose and injectors pulled out (without pulling the whole throttle body assembly)
