             I might be one because I'm finding all sorts of problems that I'm not sure are real problems. I need your help.
            
 Does a black exhaust and exceptionally bad fuel consumption have anything in common? I get about 150 miles out of a tank and I use to get way more when I bought the bike.
 
 I also noticed that the exhaust is becomming very black from all the soot.
 
 Gearing up to second has a slight clink sound and down from third to second has a loud clink sound. The rest of the gears sound like they always did.
