Ok hole in piston two times
OK i have a polaris sl 750 1994. replaced all pistons and rings on it because when i bought it it had a hole in the piston.had alot lot of trouble with crap in the carbs .cleaned gas tank,took carb apart and cleaned them .put them back together to spec high speed and low speed set to the book.installed new high volume gas filter. sublementary fuel pump.as spec.asked how the piston gets a hole in it and the sublementary pump was the remedy,but tried to explain its not #1 cylinder that i'm having trouble with, its #3 THAT BURNS UP .Whitch ONE IS #1 cylinder, the front of the jet ski or the back of the jet ski? also i found in the valve set and needle 2@ 1.5 and one@ 2.0 i thought that was weird! well my ? is how do i not get another hole in the same piston again.i took it out today and it ran great for about 20 minites then went down hill from there .could not get any speed out of it after 20 min.pulled lastplug at the rear of the jetski and found a hole in piston again.i want to fix it again but i dont want this to happin again like every one else i cant afford it to happen again.
