Hi Mike,

My comments inline:

But when I just tension the throttle cable a little bit, the revs are not rising yet, I hear this rattle. Not very loud, but it is there. It seems to come from the left side. First I thought it was the valves, but I don't notice any drop in performance whatsoever. It runs as smooth as ever, it's just that rattle.

A couple of questions:
*do I need to do both sides at the same time? They are subjected to the same wear.

Usually, the R/H side wears faster than the L/H side.

*I have a 1997 R850RT. Are the throttle bodies the same?

Dunno what you mean by the same... But I have kits for your bike, both right and left side.

*what are other effects of the wear? What's this surge?

Besides the annoying ticking sound, I have found that by repairing the TB's, a valve adjustment and a sync, the surging was gone. I still had surging after only doing a valve adjustment and sync.

Surge is when you keep the bike at a constant rev while cruising but the riding is not smooth - you would have uneven speed for small periods of time, but constant. Nut sure if observable on the tacho but you can feel it while riding, the bike would like drop the revs then come back. Most probbably to feel it while riding at 2000 RPM in 3rd gear.

*My bike's got nearly 160.000km on the clock. Is that a reasonable milage for this wear?

Most probably. The spindles on my '96 RT had wear on them @ 47k km's. It depend on how much do you use the bike inside a city, where the throttle sees a lot of action, resulting in wear.

Also I had a lot of customers having this issues on 1150's, these bikes usually have lower mileages than the 1100's since they are newer.

So it's not a subject of manufacture year but a matter of mileage and how much do you ride inside city or outside(wear is directly proportional with how much you use the throttle).

Best test is to get the fairing off the bike and get your fingers on the back of the TB's, and check if the pulleys, where the cable goes around them has any play. It shouldn't. Play in the pulleys mean that the spindles are worn.

Ok, thanks. I'll check when I get the chance.

I mean that the topic says R1100/1150, and I have an 850. So, that's why I asked.

Yes, I have checked with realoem.com and the intakes have the same code. So the kits fit to your bike too.

We can continue this discussion on PM.

As an update:

I have found that instead of using a copper wire to remove the bushings, a bent plastic zip tie works even better.

On some recent repairs I just bent one zip tie and put the screw inside it. The bushing comes out easily ;)

Hi Istvan,

I am glad it all worked out fine for you ;)

Thanks,

One added aspect I didn't see mentioned.

When I disassembled my TB's I made sure to match the butterfly plate to the bore. This of course required that the throttle stop screw be 'changed' which leads to a whole nuther level of complication in terms of getting back to the stock setting. So this step may not be worth the extra hassle for most folks.

But if the stop screw has been messed with, then do make sure you tweak the placement of the butterfly plate in the bore. Granted it's not a huge deal but it can affect the wear of the plate on the bore and will help close up the differences between the 2 sides wrt matching their idle settings.
