I had a problem with my clutch slipping and just befor i changed it i noticed that under full throtle in 2nd gear it seems to junp around 6k. i went ahead and changed the clutch, now it doesn't slip anymore but it still jumps in 2nd. any ideas

 

How does it shift otherwise? With a clunk? Check the pinch bolt on the shift mechanism... sometimes they loosen off and you get play there.

 

It shifts smooth as butter and there isn't a problem unless i'm on the throttle hard above 6k and only in 2nd
