Check your battery condition and connections to it, and the cluster of negative wire connections to the frame under the tank l/h side must be clean and firm. You may simply not be getting good current to the shift motor.
DCT shifts empty
Hi!
So, this is my last try to find a solution for my DCT Problem.
Apparently there are no Twin riders in Germany knowing this problem (Honda doesnt care),
but I got the same answer every time.
"Clean your shifting motor"
My bike had 1800km on it, when I bought it last year.
First it was all fine, but after maybe +300 km I noticed that the DCT tries to shift from 1st to 2nd gear,
and will not engage at first try.
It got worse till I wanted to ride to Italy. It tried three times to shift into second gear, then it engaged.
I searched for this issue in some forums and cleaned the shifting motor, right before I rode to Italy.
It had lots of coal residue in it, which shouldnt be normal with this low age.
While riding my bike through Italy I had the first shifting failure at about 1500km after cleaning the motor.
I let it be for the next 3000km and it got so bad, that it tried to shift 3 times every time between gear 1 and 2.
It also appeared between gear 3 and 4 now.
A friend of mine has the absolute same bike and borrowed me his perfectly working motor to test it.
It worked finde, because I cleaned it as well, but there was a failure to shift too.
He never had one single problem with that motor in his bike.
Last week I made an oil- and filter change with Motul 5100 10W30, cleaned my miserably working motor again (there were kind of big chunks of coal in the Motor after the ride to Italy) and hoped that this will change something, but it didnt.
The bike runs better, but since then I had 3 failures of shifting after only 200km.
So here I am... What could cause this problem, if not the shifting motor?
I´m really desperate and I´m considering to buy a manual bike, to change all my (optical) modifications to the new bike and sell this piece of junk.
Hope you can help me with this...
Best regards
Tim

I'm pretty sure the OP is talking about the shift motor, when he says "motor", not the engine. And what he's calling coal, is probably carbon residue from the brushes wearing on the commutator ring. If the commutator has some gnarly edges between each contact, it could be wearing the brushes at an accelerated rate.Why on earth is the oil full of coal at such low milage?
Ja, so der unter part in pic drei, the copper parts, is the commutator and die mark going around the copper segments should be polished out with some fine carborundum paper, say 600 or 800 grit. Hold a piece of carborundum paper around the copper part of the shaft with light pressure and turn the whole thing with your other hand to polish the commutator. Should only take a few turns, like sechs oder acht. That will reduce the brush wear. Definitely check the wiring connections and battery condition too. Es tut mir leid, mein Deutsch sehr schlekt ist. Aber Ich liebe ist! 😉 Veil Gluck!
Your grinding paper will be perfect. The copper segments are several mm thick and you will only be polishing out 0.1 or so of a mm. As I said, just a few turns and it will be bright and shiny again. you want it to look more like the bit of copper up near the white resin. The brushes will smooth themselves out to fit the commutator. It's only dust and electrical arcing that has caused the grooves that you will polish out. Don't try and do anything to the dark lines in between the copper segments. That is insulation. Eventually, it will all be scratched again, but right now you have a problem so we need to try and eliminate any potential cause and the scratched commutator is one of these. I honestly think it will be a battery or connection issue.
