i was just wondering what the average time was till people rebuild their trailblazers. mine is a 03 250 and i have had it 1yr this month. when i do rebiuld should i go with a wiseco piston and should i get it bored over. it is currently stock except for a k&n air filter.thanks for any input

 

Go with a Wiesco for sure. But I wouldn't get it rebored unless you have to. My friend has a 99 TB250 that is all stock and still has the original spark plug in it. So they can go pretty long before a rebuild
