I have a 2000 Polaris Trail boss and I want something lighter and faster. I have looked at a 250ex, 300ex, Blaster, and Mojave. I don't want to spend more than $4,000. I've rode all but the Blaster
My question is a Blaster being a 2-stroke how long will it last before needing the motor rebuilt? If I put about $500 into a Blaster what kid of speed will it get me? What is the best exhuast kit? How much does a big bore kit cost?How about the reliability of the motor after a big bore kit is installed?
I know these are probably commonly asked questions but I don't know anything about 2-strokes or Yamaha. Any information would help me decide whether to go red, green, or blue.
Thanks.

Personally I think the blaster is the "funnest" of the machines you mentioned, not saying its the best by any means, but it sure is a blast to ride.. You need to throw a top-end mabe once every year or two, depends on how much riding you do.. This is the second season on my blaster and to-date its running just as good as when it was new, compression is over 125lbs, good to go.. They are alot tougher than people seem to think, a new one will last you a long time. As long as you keep it clean and maintained.. $500 bux will get you alot for a blaster, mabe a nice pipe and scilencer along with a bunch of other stuff.. its gotta be one of the cheapest machines to hop-up.. Definetly try one if you can then you decide which is best for you.
