Throttle me!

So, I have managed finally to get my rough running 2003 GSA running nicely. After a lot of pratting around, I managed to balance the throttle bodies - nice

However, while I was there I noticed that the main adjusters the ones that you're not supposed to mess with; have been adjusted (the threads on it are way to clean about 5 or 6 mm on both sides) the rest is tarnished, this, I think may explain the drama I had getting it to run nicely. However it must have been like that for at least a year (that's how long I've had the bike) and the rough running is a recent issue...

My question is, do I need to worry about it - should I attempt to reset the things to factory... The oft mentioned, in hushed tones, zero-zero method? Will I be doing any damage if they are out and I leave it alone.

As I understand it the 0-0 method is not primarily for the 1150 as it uses the motoronic 2.4 rather than the earlier version on the 1100's, but it can work if you use a different value on the volt-meter .310v rather than .370v

Running sweet....

I did the deed last night - rode to work today, what a difference; this is the bike that everyone loves. Never really got it before, no surging, no loss of power under load/acceleration, no lumpiness.

The process if anyone is interested is

1) have a big think (decide do you really need to do this), drink tea and gather your nerve
2) Check you can get an accurate reading across pin 1 to 4 on the TPS (Ignition on, side stand up, but don't have engine running)
3) Loosen the throttle cables with the adjuster then loosen the throttle stops on both sides until you can see a small gap between the stops and the bit where the throttle cable attaches (what ever that's called)
4) loosen the torx bolts on the TPS
5) turn the TPS until you get a volt reading of 0.1
6) Lock the TPS at this reading - lots of prating around required!
7) Gradually turn the throttle stop screw on the left hand side of the bike until you get a reading of 0.31v (although I've seen other numbers suggested ranging between .31 to .42v)
8) Tighten up the locking nut on throttle stop
9) Congratulate yourself and have more tea, don't go near the Throttle Stop on the left, again, ever.
10) Close the Brass idle adjust screws on both sides. Then open them about 2 or 2.5 turns.
11) Start the bike - it'll run rough. Let it warm up to normal temperature.
12) Balance the throttle on right side using throttle stop screws.
13) Take out slack in throttle cables
14) Set tick over and fine adjustment of throttles using idle screws
15) job done, more tea or even a beer.
16) Test ride the following day and realise you forgot to allow for the fast idle lever, re-balance the throttles, taking more slack out of cables and fine adjust using idle screws, remember not to mess with throttle stop settings.
17) more beer......

Hope this helps someone......

That's exactly how I did it when I got my tbs back from Vern having been refurbed. Some previous owner had messed with the screws as had I. Not as bad as is made out as long as you have the tools.
