Hi there,

I'm fixing an old K100 2v and I was wondering if removing the intake box is compulsory for taking off the body throttle butterfly in order to give it a complete cleaning. If not, how should I do?

Thanks beforehand:D

You don't need to remove the plennum chamber to get the TBs off but it does get an oily film inside and you may want to clean that. You do need to remove the air filter box to get at it easily.

What's the process for getting the TBs off the intake rubbers and back on again without removing the plennum chamber, K Freak?

Is it:
1. remove gasket clamps and intake rubber clamps
2. remove each gasket individually
3. remove TB assembly
4. reverse this procedure to install TB

Both the posts are a bit ambiguous Rob. I was thinking of removing the plenum from the TBs after the whole lot was removed from the bike. I have not tried to remove the TBs only and I don't think it would be a good thing for the blood pressure, very difficult if not impossible.
So to answer Domingo again you need to remove the airfilter box then the TBs with the plenum in one piece. Getting the TBs seperated from the plenum to remove the TBs by themselves while leaving the air filter and plenum in place would not be at all easy.

Thanks, Kfreak. You just verified what I suspected. I'm going to do a TB replacement and looks like it will be a full frame-off job. It would have been nice if there was a way to do it without removing the frame from the engine but I kind of figured I was dreaming.

Thank you guys,

I'll keep you up to date about how things have gone.

I also think that the best way would be removing the airbox filter. I got a job to do.

might be a good idea to check in with gith.

he did the transfer from k100 to k1100 tbs ...and im sure there was no engine . frame removal attempted

check this thread

I need to redo the post so here goes. (we all have different names for parts and it does get confusing especially for my ancient and overworked brain)
The plenum is the box directly above the TBs and does not need to be removed from the TBs but the air filter box on the right side does have to come out as well as the Air flow meter part of the air filter box, it can be left connected to the bike and will fold back and sit on top of the frame if the electrical cable is not tangled with the TPS Cable.
Even with the air filter box out it is a very tight squeeze but the TBs and plenum as a unit does come out in one piece.

Hi there,

I'm here again and the job is done. What I did was removing the snorkel on the right side and also I took off just the air filter. At that stage I could loosen the clamp's screw which holds the big pipe betwen the plenum and the air filter box. Once I pulled this one there were no problem and I got the TBs in my hand. Easier than expected.

Thanks for your quick responses.

I'm totally sure this won't be my last question

yay !!

I'd like to say that I had absolutely no intention of annoying anybody posting here. It's been a matter of total ignorance, maybe I should have read the main page before posting. Please, accept my excuses, I'll try not to do it again.

Good on you as they say in NZ, please don't be discouraged. I and every member looks forward to reading more from you about riding in Spain and to further questions.

The main reason we try to keep questions in the relevant section is that it enables people in the future to browse a section and find information more easily and to keep an eye out for questions about an area of interest to them.

There are many members with a huge knowledge of these bikes that have the most incredibly detailed information in their heads and getting that information is so useful to the rest of us who want to work on a given area of the bike.
