Did you ever check you tank vent tube?
motors fried. i got a 99 indy 500 anybody want some parts? lol bye bye citgo sea and snow
The oil did not make the crank seal go bad, if that is the problem. Over 20,000 miles between my brothers last two sleds and my last two sleds on Citgo. The oil did not cause the problem.
So how in the world is it the fault of the oil ??? You have a lean fuel mixture... more than likely by ripped carb boots or plugged jets in the carbs..... OIL WILL NOT BURN A HOLE IN A PISTON.
If you no longer want to run Citgo... you can send it too me...I'll use it. I have 9000 miles on my Viper and it has never had the engine apart.... but I know how to clean carbs.
my buddies acted the same. guess what cdi box fixed the problem
2005 Polaris switchback/RMK 600ves. newer 15x144x2 track, slp skis, handle bars raised 6 inches. scratches, cover, etc. etc. etc. no problems ever. Changed drive bearing when installed new track. Well maintained. Ready for trouble free riding. $3000 , comes with trail pass for MI. Ready for boondocking, or anything else you can find. Motor has never seen discount oil. All others $3500.
magor air leak or lack of fuel = big whole , very sad
Indy what happen? I thought you said in other threads that is the best motor ever made for snowmobile. lol
I blew up 2 of those motors, 1 in a 1991 500 and a 2003 500 rebuilt them both 1991 is long gone still have 2003 still running good with over 10,000 miles on it.
rebuild it not that hard you can do it. redo top end and new seals be good as new.
I have always ran citgo sns!
Buy a yamaha and change your name to teenvector, teennytro or teenapex. : ) No, more engine problems.
03 500 is different motor and 91 500 was like the first year of it. still one of the best motors, i got 8,000 HARD RIDDEN miles out of it.
