I noticed whenever I power wheelie, there's this hard click noise and I can feel it when it happens. I'll typically be doing 30-40mph and hit the throttle, simultaneously, there's the hard click and then it's gone but the sound usually makes me sit it back down. I just noticed this but I also just learned to do decent power wheelies so I'm guessing it may be the chain/sprocket? Haven't gotten a chance to look yet but was wondering if anyone has had a similar issue and if I'm thinking in the right direction with the chain.
