I am sure that your bike didnt blow up because it had a 170 in it, a 158 is stock. There is another problem. I ran a 175 in my 04 and won a LOT at the sand drags. I have a 168 in my 06 but it has very few mods (I race XC now ). There are a lot of variables with jetting but most similiar bikes are going to be real close. What pilot jet and needle are you running?
