Hi all, newbie here.
Long time Yamaha snowmobiler, new to Totallyamaha. Neat to finally find a site that still talks/knows TSS sleds.
I bought a clean 1990 Exciter last Spring ($400!) It's all cleaned and prepped to ride now, but I have a question.
The air vents immedaitelt below the fairing; is that the air intake? As I recall from my "old days," the Bender cold air kit covered over the top of these two vents and sucked air from the back edge.
This Exciter has a plastic cover under the vents that seals them closed. I assume this is to keep snow off the carbs, but do I want this plate there? I ride mostly trails so not a lot of snow will actually get there. Should I remove this?
Also, are these carbs liquid heated? I see a line from the thermostate area of the head going to each carb.
Thank you,
Tom

Yes the carburators are heated with engine coolant and the hoses were the cause of some short rides if left to rub on something. Make sure they are well secured. Unless it is extremely cold where you ride I would find a way remove the lines from the head and plug them. I think later models had a valve that could be turned off, but i don't remember exciters having a valve. The original idea was to prevent carburator icing.
In regard to the block off plate, I would remove that also, unless (again) it is extremely coolldd where you ride. All exciters had a breathing problem which at its worst would cause vapor lock in the carbs.
Unless you are operating in deep snow(which the exciters were not very good at anyway) open up all the hood vents and let some air in there. Also, make sure the carb bowl vent lines are in place, secured and extend all the way down to the bottom of the block. Sometimes these vent lines get out of place or worn thin or broken or removed or whatever and cause venting problems for the carb bowls(especially on exciters).
Also, when you stop for a break, prop the hood up with your helmet, let it defog a little bit and let the engine compartment air out. Keeps them darned exciters from vapor locking!!
Good luck with the exciter, they were a lot of fun once you learned all their little tricks!!
