I'm wondering if he would be better to leave it the way it is as well. It's great to see a low mileage survivor. It may not look like it just came out the showroom, but it is original and would make a great rider. Go through it and make whatever minor fixes are necessary to freshen things up and make it reliable. You can restore a sled a hundred times but it is only original once.

Having the rear bumper/lift bar attached with four bolts would be better than just two.

Many tomorrow I will switch the carbs and see if the other side fouls out ir misses... That should give me a better idea whats up here. Theres a few wires need gone over too.... But if I'm taking the machine down I'm likely just wastIng my time playing :D
I would not change the carbs from side to side. There was a service bulletin that came out later on that instructed the carbs jetting to be changed for each specific cylinder. Just clean the carbs taking note of what carb has what in it and keep them seperate. Nobody wants to clean carbs you just have to do it.

The vents under your windshield are open. Later there was a kit that closed them, then I think in 81 they molded these vents shut. In the lower clutch side of you belly pan I see someone blocked off the holes for clutch cooling with a plate. I am not sure if that was part of the aforementioned kit or not. Someone on here knows more about it than me and might chime in.

That sled could use a little work here and there but overall a very nice original. If you want to restore one there are others in much worse condition. Take your time dont rush into anything. It will ussually cost you more if you are in a hurry.

Good luck

Nice find. I like 80 Liquifires, even if Deere built nearly 9,000 of them.

Technical advice: Crank seals! They don't last 33 years. The missfire on the mag side might be a lean condition caused by a leaking seal. Bill is right, there should be a cover under the hood vents below the windshield. I would suggesting getting one from a parts sled, as I think it affects radiator performance.

Tasky, you have a point about the jetting being different from side to side, but I thought that didn't start staggering the jets until 1982. Worth checking the carbs to see what you have in them.

Good luck with the sled, and I agree that she is pretty.

Thanks guys. Question .... I heard swapping out the carbs with that from a arctic cat jag 440 fixes the finiky from these machines. Eliminate the odd carb setup where they used the float bowl ad apart of the carb function. Any truth to that?

As for the restoration, I'm still on the fence.. Likely will. Hey, does anyone here have a pic if the underside of their 1980 hood? Would be good for comparison to see what I'm missing and how it's placed exactly. Thanks!

I can hardly wait to get her up and running again. My only regret with this sled is not starting the de-rigging and restoration sooner.

Older post I see, and nice find!! Looking at that miss-fire on that sled with that low of miles, I would have to comment that it looks to have been an on- going problem for some time. Look at the paint left on the Y pipe of the mag side compared to the PTO side. Shes had a cold cylinder for a very long time on that cylinder...Rob.

The misfire turned out to be the rev limiter, unplugged the miss is gone. I Replaced the limiter and the new one causes a miss too, I can only assume that something else is causing it.

I ran the sled for a few days, over heated it and the head gaskets let go. We are past that now and the the sled is back together and running decent.

Starts easy, idles good, runs like new for about 10 minutes then it gets lazy anything beyond 1/2 thritottle. I wonder of I should replace the or coil. Seems like the problem is related to heat, like the electrical is bad.

Anyways, here's a short video I took just yesterday
