I looked at a 97 blaster for a guy today[he wants me to repair it].it was super clean until I pulled the jug.Piston and cylinder walls had a gouge and scratches,rod bearing seized,but best of all the 1st thing I noticed was the piston was in backwards.He said he had owned it for a year and had been riding it,but I was really slow but ran until it locked up.Has any 1 else ever seen a quad with the piston in wrong?
