Second Gear Slipping

And it's worn halfway up the sides too if it's the guy I'm thinking it is...sports bikes would be struggling against him...
 
Been getting the same thing mostly when its cold for about a month .

You pop it in second it goes in and starts pulling through the gear all of sudden feels the like pinion on the bevel drive is 3 or 4 teeth missing or it like you hit a pot hole and got a bit of wheel spin ..I shut the throttle think wtf and gear engages again .

Funny enough my bike is an 06 also and its only done 25.000 miles ! not best pleased about this
 

Only in second? ....'cos that there is dislodged circlip symptomatology...
 


Mine has about 4 the same mileage as yours. I have yet to have a good look at what came out of the be beast but will do on Saturday and post some pictures of the dog gear and the input and out put gear of the second gears.

Was a very expensive repair but what the heck in the 16 months I have owned the beast I have spent 10k on it

Yep only second the rest of the cog swapper works just fine .

Even if it is just a circlip have to remove the gears shafts from the bike ?
