Driveline vibration happening under anything but light load ONLY in second gear from 1500-2800rpm or so.

I think my flex disc is ok. Don't know about the driveshaft center bearing, but if it were one of these, wouldn't it happen in all gears?

Driveline related, flex disc, csb, loose or unbalanced driveshalf can all cause it,get someone to look at it

^^ lol thanks for telling me what I stated to begin with.

Thanks rider, I guess that's most likely what it is.

If you know everything, don't ask for advice.

Drivelines are really sensitive, and 1800-2300 rpms is what speed range? If you're going that speed in first you have a lot more load therefore less play in driveline and less vibration. CSB is the second thing to check after flex disc, so go check it.
