First of all i would like to say a big hello to everyone!:banghead:

Im new here & have done a search on this problem which seems to be very common! :cheers:

But i would like to describe my symptoms before i go ahead with splitting my cases.
My bike is great through gears 1st to 4th no probs but in 5th the gear seems to stay in but every 2 seconds ish the bike snatches only when i have the power down? but is fine in 5th if im just cruising about 1/4 throttle. Does this sound like a faulty transmission or something far simpler?

Any help or advice will be greatly recieved.

Worn lugs on the 5th and third gear pinions, and a bent shift fork. Time to split the cases.
