Default Jumping out of gear.

So rode to work this morning and my bike wants to act op on the commute. It will ride just fine till I hit the Rpm's hard, then it feels like it is jumping out of gear and bouncing off the rev-limiter. I can put it back into gear and will jump out again if the Rpm's are too high. But if I bring down the Rpm's, it will ride just fine with no problems. I was thinking it was the gear shifter wearing out, not able to keep it locked in gear, but what is the consensus; clutches, shifter?

So been reading around and when it gets above the 7,500 rpm and it starts to jump or slip clutches, time to change out clutches. I am also going to do a write up video on youtube on how to do this with a Pro shift kit while I am at it(Might as well).

I have heard that OEM clutch packs are best. Can anyone recommend aftermarket companies like Dp or EBC?

slipping out of gear is usually because of worn gear dogs or bent shift forks. I doubt this has anything to do with the clutch.

I'm assuming that we are talking about 2nd gear here or does it do this with all the gears? What happens when you shift from 3rd down to 2nd and then run it up past 7k, does it slip out of gear then too?

Seems to be all the gears; 1st, 2nd, 3rd, etc.

It may not be jumping out of gears, seems that way though. Might be slipping. But only happens when I start to accelerate quickly.

I will see if I am right on the way home. Just started on the way on my way to work.

When it jumps 2nd does it go into N?

If you have a worn/slipping clutch, under hard acceleration, there will be a rise in engine speed (revs), without a corresponding increase in road speed. This will be more noticeable in lower gears and will increase as the clutch becomes more worn.

Jumping out of gear, is like the bike slipping into neutral and losing all drive and the engine revving freely.

It's not clear from your description, which symptoms you are experiencing.

Feels like it is jumping but pretty sure it is slipping, but when only when it revs high. Goes to a neutral feel, switch gears and the same until I bring down the RPM's. I can ride it fast as long as I slowly bring up the rpm's. So pretty sure my clutches are gone.

Good aftermarket companies for clutches? Everyone always says Honda is the best though.

Your last description sounds more like a slipping clutch. When you rev it up, it slips.

If you let the rpms come back down, (without shifting) you should then be under power again and you can hold a constant speed. If this true, then it's the clutch that is slipping.

I've never replaced my clutch yet, but if I did, I'd go with oem honda ones.
