problem

So about a year ago I bought two blaster and really mainly focused on 1 but now I’m working on the 2nd one and I think some work is done on it but I’m not sure what but I took it out one day to test it and it ran great then I sprayed it with some water and slowly the rpms go away and then...

My Dad owns a 1998 Yamaha Blaster that was in the woods for years. We pulled it out and got it running good, few days later it would die out on you when driving and make this nasty clicking sound! I tried researching it but cant find much.. I'm no expert so please help! Also clicking sound...
