I just got done riding the 250 around. But when I was done and shut it off.. I hear this sound it sounded like a the fan was still running, if bikes have fans I Don't know lol. But it was like (thump thump thump) kinda like a fan was spinning around wile it was slowing down. it started off fast but in about maybe 2-3minsloweddow and stopped..
The guy I got the bike from did not have the owners manual, so I cant read up on my bike and what's all in it

So any one know ware I can download a 2008 ninja 250, owners manual?
