I have had my Griz600 for over a year now. I noticed last month a wining noise when I slowed down and now the bike wont move at all. The high gear will bearly move but the motor revs way up. The low gear does not work at all. The rev limiter keeps the reverse from going anywhere also. I am probably going to drop it off at the Yami shop near my house but would like to know if anyone has any idea what might be wrong. I can work on old cars and trucks but the 4 wheelers are not anything like I have worked on before. Any suggestions or ideas would be great.
