sudden jerk

[jch364]

ok so here is what just started happening today. when i leave in first gear and hit it hard i feel a sudden jerk. same for second when i screw it on good. when i am riding normally nothing happens. smooth shifting no problems. no jerking. now. i just put a new clutch in last week. i dont think that is at all the problem. i am hoping that it is not transmission. i do have 42k on it but this is a sudden problem and only when i hit it hard.
I think that it is the front sprocket needing replacing and is slipping. it has been on for some time. been to the drag strip several times. of course i will have to take the cover off to be sure.
anyone have something like this happen?

I would check the chain and sprockets, and the cush drive in the rear wheel. It could be slipping too.
