I would just install the Witt with new coils and be done with it. As for the accelerator pumps, I removed them from my Ducati 750 as well as the RGS and never noticed any performance degradation at all.

Lost count of the number of times I've said that on this forum. Each to their own I guess. There are those who swear they give the bike a great big kick in the arse ... Not so sure. if you want to be able to impress your audience by twisting the throttle on the stand and have the revs go ballistic like a fabbo GP racer in the pits, they're all yours!palebird said:

Okay, so ordered a variety of main jets and pilot jets. We are going to try those out in different combinations, all having all three 3 idle mixture screws reset to 1? as a starting point.
Now, it's near 1 1/8'th of a turn on all three.
It seems as if this is a sign of too much fuel at idle and the extremely easy starting could also point in this direction.
I've read somewhere and on this thread that a 1200TS should have #65 in pilot jets, but I am not so sure that thsese Work optimally. They may deliver too much fuel in the beginning and when it crosses over to mains, they may be delivering too much fuel. Just a thought.
I will try installing #135 main jets because of open filters and open exhausts.
Then if it's choking, I will vay those a bit up and down.
Then I will try a variety of smaller pilot jets, hence the assortment of 10 sizes of main jets and 10 sizes of pilot jets, all with small increments, that I just ordered. I'll use those for my own bike as well.
It seems from other threads on here, that some 1200TS bikes use #60 pilot jets.
I'll report back asap.
Kind regards,
jacques

Hi Jaques. Suggest you concentrate on getting your main jets right first. They do exercise some control over all conditions, to a varying degree - not just WOT.
My money has always been on 'much too-rich' for you problem.
You can experiment with rich-mains by blocking (reducing) air flow into the carbs. If the problem gets worse, you know which way to go - leaner mains.

Thanks, I'll experiment some more asap.
Tonight I installed a set of new #135 mainjets, instead of the #125 that was there after we tried a set of #110 which were way too small,a dn it ran terribly.
The #125 faired a Little bit better.
And tonight the #135 went a Little better stil.
So, inwards with the idle mix screws to compensate not to overfuel all over, and it drove a bit better still.
The problem is now, that it cannot pull on quick gasgiving, but if you give gas slowly, it picks up and goes all the way to 8000.
Well, we don't actually know, because the tacho cable broke. A new one finally arrived today. Great.
In first and second gear, it flies forward compared to earlier. 3,4,5 not at all, only when giving gas slowly.
So, problem are the same, but lesser and lesser.
A long pile of various main jets and pilot jets are now on it's way.
Also, we took a closer look at the dissapearing low beam. Sort of the guest of the week, and it turned out to be a few Things: some green corrosion in 3 electrical multiconnectors in the headlamp, and a slow relay plus a near broken wire on one of the supplies to low/high beam. All fixed now.
My friend installed a new manometer for the two interconnectes rear dampers and a new front tire plus inner tube. We fine adjusted the pressure to 32 front and 37 rear which felt fine.
I think we are getting nearer.
We have soem nice 40mm downtubes and big bore collector ready for installation in a few days.
My friend will install a new LED headlight into the old headlamp housing, which should minimise amp usage and enable low beam daylight driving (mandatory now in Denmark), plus actually cast a light beam
We'll see how that fares an dI will comment on that here as well.
I'll report back on how it fares asap.
Kind regards,
Jacques

Oh dear. I've never seen so much light out of a motorcycle head lamp!
It's extreme.
Fullblast.dk makes these.
Drove some miles on the motorway today, and still cannot take full throttle, except when done slowly, but it does drive fairly fine in 1'st and 2'nd.
My friend said that he did notoce an overall improvement after getting the #135 main jet.
Will try to see if we can find soem time for playing wilth pilot jets maybe tomorrow.
He's so stubborn and won't install the Witt Mk. II untill bike is running as it should.
Hmm...
Before we started on all this, it started easily and could idle okay. Hard to do anything in any gears.
Now, it's well idleing and pulls strong in 1 and 2. Slow in 3'rd,4'th and 5'th, but will eventually catch on and hit high revs, running fast.
Also worth noting was tha tbefore, it could hardly reach 110 km/h when driving nicely. Now it pull strongly past 130-140 km/h, but needs slow throttle to go higher.
Will report back as I'll get a chance to do anything to the bik
