I need some answers QUICKLY!!
ok so i just got this badass 91 superjet 650 with group k hammer kit, i took it out riding today and it was awesome, the guy told me that the bendix was going out, so i planed on replacing it, and expected it to go bad.... it did at the end of the day after riding for at least an hour. so i pulled the motor just a little while ago, and decided to do a leak down test while i had it out. i pumped it to 8psi, and heard a hiss, the pressure droped to abt 6.5-7 psi and then held, so i sprayed soap water all over, and i saw where it leaked, it was the rear crank seal, but once it hit abt 6.5 psi it didnt leak down any further..... soooo then i go to take off the flywheel cover, and once i get it off, the whole area is covered in a coat of rust. i almost expected it when i saw that there was sitting water in the front of the ski when i got it, but anyway, so i pulled the flywheel and the stator is covered in a layer of rust as well. so here are my questions:
1) is it ok that the rear seal leaked down 1psi then stopped and held for over 2min at abt 6.5psi?
2)if the ski ran so great today, the stator obviously isnt bad bc of the rust everywhere, so how can i clean it off with out damaging anything? i used brakeclean and parts blaster on the flywheel. im sure the rust is the culprate to why the bendix isnt working right...
3) should i take some light sandpaper or something to the magnets on the inside of the flywheel?
i did do a compression test when the bendix was kicking in, and both cylinders were at 175psi, so as long as the leak down is ok, i believe the rest of the motor is in sound condition.
I appreciate the help,
Chris
