Wow, that gear is roached. I would replace it. I would also closely inspect the gear it mates with.

Mate that's right through the hardening and bits will fall off soon. Inspect every gear.

Either you have been unlucky with a badly manufactured gear or there has been some other stress, perhaps oil related in the past.

That damage is going to get worse and the bits of metal that fall off will wear or damage other parts in your transmission.

There are some used transmission gear sets on Ebay. You will need to check the part numbers to make sure they cross over to your year bike.

Thank you for your help.
On ebay I just found the whole clutch.
not what I need. I need primary gear 5 and primary gear 3and 4 and then those opposite.
