I've just completed the first thousand kilometers with my new HP4 and I'm able to reproduce what seems to be a DTC bug:
When in second gear between 20 and 40 km/h, gas almost closed, almost no traction, the DTC light sometimes blinks (fast orange blink meaning "DTC is working"). Of course, based on these conditions, it should not blink at all.
Although it is not systematic, it is easy enough to reproduce it and, with a little training, to even keep the DTC light blinking for few more seconds (trying to preserve the low traction and low speed conditions).
During a specific 10 km testing session I was able to get it maybe 20 times or even more.
This happens only in Rain mode or Sport mode (I was not able to get it in Race mode and did not test Slick mode).
I checked it happens with or without the heating grips switched-on (could have been an electric power issue, but it is not).
I checked it happens with the Slick plug in or out. (Not sure if the fact the Slick plug is inserted has any effect on the other modes. Remember that it is a French bike and the Slick plug also enables to bypass the stupid French 100 horsepower limitation).
I checked that the chain is normally stretched. Maybe the chain being too loose could have had an effect in case the DTC also monitors the engine RPM (not sure it does). But it was not this.
It is well the quick orange blink meaning "DTC is working" that I get (and not the slow orange blink occurring at bike startup meaning "DTC not yet ready").
Few videos of the case can be found here:
and for info a video of the slow orange blink occurring at startup to show it is not this one that appears in the above tests.
I will have the bike serviced for the first thousand kilometer service this week.
Maybe removing the 9000 RPM limitation will solve the issue but I would not bet on this.
Other HP4 owners experiencing the same issue?
Any suggestions for a resolution?
Thanks in advance for your feedback.
