About a week ago I purchased my first quad a 2001 Yamaha blaster. It was a family friend and got a good deal. It runs and drives great, back brake needs some work. However when I did a compression test it was stuck at 100 psi. The guy I bought it from said that the top end had just been redone and it hasn't even had a full gas tank through it. It was sitting for a couple years though. I am very stumped and I have no clue what to do. I was thinking that there is a leak in a gasket or something, or maybe that the head wasn't really redone? I just would love some advice on what to do.
Thanks.
