I was at my friends house today and he wanted me to try the bike out with the 01 clutch mod. So when I started it it was smoking like my yz125 when I first start it, It did it for about a minute and then went away, I was alot of smoke. then he told me it did the same thing yesterday when they took it out of the basement and fired it up. the oil is'ent over full, and it runs really strong. what do you think it could be??, I was thinking oil could have got in the carb when they carried it up the stairs.
