my coolent resivore in my 03 rx1 was at perfect level when i started a weekend of riding and afer 250 miles the resevore was empty? no visable leaks? dont think its in the oil but has there been any know issuses with head gasket going bad in these motors where could it have went. i nitice alot of steam coming out of the vents hood vents when i stop on the trail is this normal too

If you are leaking coolant in the Engine Compartment, steam would be an indicator. I would check all the coolant lines and connections. Don't forget the one under the carbs, and down under the battery, etc.
The only ones reporting problems with head gaskets are turbos and that is not very often, either. There is no trend on Head Gasket failure.
Steam could be coming from melting snow, also. If you are riding in powder that is common. If you are not riding in powder, then I would say you may have a coolant leak down there. You may have to remove the Airbox and Battery to find it.
You can run a pressure check on the coolant system, if you can find a radiator handpump with the right size radiator cap.

the 03 rx would spit out coolant if it was at the full line in the tank, it seemed fine if left an inch or so below. fill it back to the line and ziptie a folded piece of paper towel over the end of the vent tube coming from the bottle. take it for a ride and check the paper towel, if its green you found the problem. as long as there is some coolant in the bottle when cold its fine. as for the steam, most is from the track blowing snow into the motor through the front of the bulkhead, 4 big holes for 4 small pipes.

The coolant level in my sled tends to sit well below the line. If I fill it up to the line, after a ride it is back down again, and when the sled is cold the bottle is nearly empty. It never goes down any more and I haven't noticed any leaks.
My guess is that the bottle is overfilled, even if it's just up to the marked line. It's most likely barfing the extra out of the overflow hose.
Like grader said, user a paper towel and rubber band to confirm it.

YUP..I agree with RaWarrior.
Mine is the same.

the bottle was completly empty after the ride y would it stip it out the overflow if it wasnt over full to begin with.

Check it when it is hot . Mine is almost empty cold but full when hot .

do you smell it (sweet smell)?

I doubt you would ever catch a whiff of coolant unless you had a big time leak and it was dribbling onto something mega-hot.
Matter expands when it is hot from higher kinetic energy on the atomic level. The atoms are buzzing around much faster when hot so collisions happen more frequently, slightly enlarging the substance. On a good groomed trail, the temperature of the coolant in my sled hovers right around 160 degrees F, measured at the intake to the engine. The temp light trips at 210. If your sled was originally at 20 degrees, that's quite a temperature swing in the coolant, and it's not odd that there could be a couple more ounces of coolant (by volume) in your system when hot. If it hits the cap with enough pressure, the button pops up and barfs excess out of the tube.
If it's not coming out of your overflow, the next place to check would be to stuff paper towels around the connections between the rubber coolant hoses and the steel tubes on the engine. Those can corrode and leak in time, though usually only if they've been recently removed. After a ride where the coolant went down, open the hood and remove the coils. Look down into the spark plug wells. Any green stuff in there? Shouldn't be if the seals on the coils are good, but it happened after I installed the temp gauge on my sled and one connection wasn't good.

All these variances in coolant level seem a bit odd. Mine seldom moves hot or cold. Maybe moves a 1/4" at most.
