'93 Arctic Cat EXT 500 EFI - Snowmobile Forum: Your #1 Snowmobile Forum

I just had a cylinder go out on my 1993 EXT 500 EFI....2nd time in 2 New Years. I found out last year that the previous owner had sleeved the cylinder. I sent it to Arctic Cat thru my dealer for ~$850 to re-sleeve it but it blew again. I'm left with one good cylinder and an EXT I no longer wish to fix. Any ideas on how to locate folks looking for EXT parts, particularly a good cylinder? Or, where I can locate a used, original AC cylinder? The sled is in really nice shape...no cracks in the fiberglass, no tears in the seat, etc. Thanks.

have you cleaned the carbs every fall? any seasonal service?

changed the seals? something had to cause it to go, if you burn down a piston and dont cure the problem its gonna happen again.

It's fuel injected, so no carbs to clean out.

As for the seals, I'm assuming the dealer took care of that when he rebuilt the cylinder last year. I guess at this point I'm either looking for another cylinder or to sell my one good one. Any recs on where to look? Thx.

punch used snowmobile parts into google, you have lots of choices. and dont ASSUME the dealer did the seals, make sure they are done.
