I have a raptor 660 that is doing something a little weird. If i just go along slow it is fine but once I put some pep in it the thing seems to skip every 4 seconds. At first I thought the chain was slipping but I can not see any wear or visually see it slipping. When it does it there is a loud clicking/clanking going on. The weird thing about it is that it does get up and go and will accelarate even while doing this. Any suggestions?

 

are your sprocket's in good condition not worn out?
