Hey guys I have a 03 blaster with open air box, fmf gold series pipe and fmf power core 2 silencer. I checked the main jet and it's the factory jetting. The quad seems to run strong and the plug is still on the blackish side wich makes me think I should leave the jetting alone. I just want to make sure I don't melt or break anything without the proper jet. Any info would be great.
