Loss of power, surging

Trauma said:

I have had a strange issue while riding on the highway. It happened once a while back, cruising on the interstate at 70-80 mph - then a few days ago, happened 4 times during a trip on the highway (200 miles each way), same conditions, 70-80 mph after the first couple of hours.

The RPMs drop to near 0, and then surges up to a few thousand, then back down to near 0. With full throttle, only going like 20-30 mph. Constant up and down cycling no matter what I do with the throttle. As I try to limp to a ramp it slowly recovers, then is fine. May not do it again for another hour.

I have an appointment with the dealer I guess to look for some codes, as it is not reproducible.

What did the gauge cluster look like? Mine did something very similar and it turned out to be a loose battery connection lol

I was riding at around 70-80 kmh when all of the sudden the bike was surging and the tach looked like a xmas tree with all the different warnings coming up. It would drop rpms and then all of the sudden go back to normal. Stopped at a friends and sure enough she wouldnt start. Went to go boost and thats how i found out the negative connection to the battery was loose
