125-200cc 3rd gear "skipping"

I have a 96 wxc250. The sprocket deteriorated quickly without noticing and I began to hear a clunking. When I checked I realized the front sprocket had lost about 6 teeth. I changed sprockets and chain but there remains a problem. Now, only in third gear, there is a rhythmic clunking. I haven't opened it up yet but I'm thinking the chain probably jumped on the sprocket while I was riding in third gear and when it grabbed I think it snatched a tooth or two off of the third gear on the sprocket shaft.

First, do you guys agree with that line of thinking? Anyone deal with something like this before?

Second, where in the heck can I get a new or used third gear?

Maybe a moderator can change the yellow cc icon to "all 2t" please. Sorry

I would think you could still order new gears.

the gears for third are shot. best to find a spare transmission or parts motor. 2nd and 3rd are what get hammered. sometimes individual gears are expensive. the good news is that are very wide range of years will fit your bike. time to split em and see if anything else is worn. i wouldnt ride the bike anymore.

Thanks. I'm going to open it up Thursday.

Gear failures arent really that common, but it does sound possible in your case.
