She’s being a pain in the but and of course she’s missing pieces

Better you then me...lol...I'm no mechanic

those XLT extra light triple were popular around here for a while.

I think my brother has one yet

I hate those triples.
They run real smooth...until they don't. Seems like it's usualy something expensive; like a broken crank, burned up cylinder/piston, etc..
Throw them away at that point.

I see a pair of vise grips, so you're on the right track.

Have fun.

They always semed to have one plug fouled. But, for the record, there wasnt a better sound than those triples when they were running good....they roared

Plug foulers.Nice wide open,,,fouled plugs if you idled for more than a couple minutes.I "rescued" plenty of them with an old Polaris 440 fan cooled.

I had a buddy that bought one new and I had it on a tow rope more than once.

Most guys here stuck them hard in the road ditches breaking trail.

I never knew a snowmobile was liquid cooled

Owned a few in the day. Blowed one or two up as well until i learned. Easy to fix a blown piston. Dingleball hone the piston and slap a new piston in her. Good to go. Biggest issue with plugs was not having the carbs sinked. Once I started paying attention to that I never had another issue with either of them.

Some, not all

I have 2 of those in my shed, I like em most of the time, ones missing brakes both ran a couple years ago when parked but not enough snow and too heavy for what I use em for. Got a light skidoo wouldn't trade for the world. Xlts I'd sell for 1K together lol
