Hello everyone, been lurking for about 6 days now searching feverishly to see if anyone else has had this, sadly I simply cannot find any matching posts.
tl;dr= rotating wheel while in center stand causes a clunking noise as if gears are being engaged loosely.
I recently purchased a 2010 VFR1200FD that I've had my eye on for sometime. On the drive home however I noticed that approaching stop signs I can hear the something making a chattering noise. When I got home I put it up on the center stand and while checking things over I believe I stumbled upon the source of the noise. Now I have to question, is this normal. Allow me to describe:
1. Put the motorcycle on it's center stand.
2. Start the bike
3. Shift it into drive (hear the clunk of the DCT engaging)
4. Cut the engine off via the key (this leaves portions of the transmission engaged)
5. Grab the rear wheel and rotate it CW and CCW
What I note when I do this is that there is small amount of distance that the wheel is easy to rotate (~20 degrees), then it's as if the linkages hit something that causes resistance inside the transmission and small clunk can be heard. If I rotate the wheel vigorously CW and CCW it actually makes a clunking noise as if two cogs are hitting together. Almost like that feeling when two gears have to much spacing between there teeth so there is space between the point of engagement.
I've change the final drive oil, and while doing so felt inside and note that there is no free play inside the gears. Then removed the lower fairing and felt the drive shaft through the rubber dust cover and note that there is no free play from the shaft. What I mean by no free play is that I can feel an equal amount of rotation of the drive shaft for the amount of turning I am applying to the wheel.
This leads me to my suspicion that perhaps there is something in the transmission.
So here's what I need help with:
1. Am I crazy and this is normal for a DCT?
2. If you have a DCT with a center stand, can you please go do the same thing and let me know if you find.
Final note, I have called a Honda dealership and they ran my VIN and this bike has had the recall work completed for the final drive and shaft.
Edit (Final Update and Closure)
So in the end, this just comes down to a poor design in the Honda VFR1200F and FD transmissions which includes a bit to much backlash. Such that at lower speed the wheel and transmission keep racing each other, this causes the backlash to knock the gears back and forth. Sometimes the wheel is moving the shaft and sometimes the transmission is moving the shaft. When the vehicle switches between these two states the backlash knock occurs.
