Im looking at replacing my stock transmission pulley with a higher number of teeth pulley (stock is 32 I think, I want 34 to lower RPM's on highway) has anyone done this? Pros or Cons? Also, how indepth is it, Im offshore so Im not looking at the bike at the moment to an idea. I know you have remove the Primary Chaincase to get to the pulley, once the pulley is off, are there any other seals on the tranny that need to be replace??
