yeah if u have the gauge give it a try and see what its at .. it should be around a 100psi .. yeah i think mine had some type of sound when my compression was low ..

yup np .. i would go with wiseco when u do your rebuild ..Yamaha Blaster Wiseco Piston Kit 1988-2006

yeah i got it started and rode it around the yard for 10 minutes and its down to 25-30 pounds so i guess its time 4 a rebuild
