so i'll go for a ride, it'll run fine going up the trail (low rpms 7200 once its running but i think thats clutching cuz my plugs are always a nice color) but anyways it'll run consistantly up the trail then i go and do a few carves in the powder and it boggs down like i lost a cylinder or 2 and then will just start running again, and cut out again. could this just be water getting in my wireing? or a weak coil? it doesnt do it at home when im trying to work on it just when i get up in the mountain in the deep snow, i need to figure out how to track down what the problem is, any ideas??
