I might recommend starting another post regarding the cel and give a bit history...it might get the attention of someone who has or had a similar issue...as it is now it's kinda buried in a tangent...but hooking up the rapid bike to a pc to verify everything is ok is a good place to startWhen I posted about the code, that was the first time I saw it. I have had the bike for only about 1,000 miles. The code popped after 150 miles or so with the rapid bike. have not restarted the bike since the code originally popped up the other day and yet the code remains present just with key on, didn’t have to start the bike. With key on I was able to change riding modes. The bike appears to function properly which makes me believe it is sensing some variation secondary to the rapid bike. I have not yet had time to connect my pc to the rapid bike and ensure all the rapid bike software is up to date. The seller told me they did it prior to shipping, but it couldn’t hurt to check. I was under the impression that rapid bike had made software modifications to prevent adjustments below 3500 rpm and avoid the CEL. Maybe not so ironed out yet.
