I bought a late 90's yamaha blaster for $250.

At higher rpms before i shift, the engine will occasionaly pop.

I'm thinking this is a bad head gasket

I'm not sure what year it is, so i was wondering if yamaha had changed anything on the engine requiring different size head gasket.

When i got it i mixed a gallon of gas with a 32:1 ratio with the yamalube 2 stroke oil.

I only rode for about 45 minutes before i had to turn it to reserve....

I'm new to 2 strokes but i didnt think it would get that bad of mileage from a 200cc motor...

Again this maybe because i'm losing compression from gasket

Anyway you can help is appreciated, thanks in advance.

Sounds like a jetting problem. My blaster was all stock except for a FMF fatty with LRD silencer. I can go on an all-day ride and still end up with half-3/4 tank.
