I've had a YZ250WR Blaster for about 15yrs and I'm still working on it. But my all time favorite hybrid is Paulie B's 400 Blaster!
IMHO .. 03 thru 06 Blasters with hydraulic brakes are great atv's. The engine has lotsa potential without ruining reliability. I love the transmission that suits the Blaster perfectly. The suspension is where the Blaster needs help. Unless you have a need to solve a long list of little naging problems I'd recommend a late model Sport quad that already meets your performance needs. Do the regular maintenance & ride!
