bogging trying to engage clutch rmk 900

hey , i have just got the new motor into one of my rmk's its idling fine but i have it up on the stands and when you rev it , it will bog out and some times die, unless you go slowly and then as soon as the tracks spinning it will rev fine.

so i imagine this is the clutch ?

i havent tryed riding it yet so im not sure what it dose with any load on it

also it has the check light flashing once but constantly is this tps ?

sorted it out , was the tps ( wire had come out)
