There are 4 warm air ports that are incorporated into my hood. This pulls warm air from the engine compartment along with the the factory cold air intake. 100% completely stock setup.
The question I have is....if I block off the warm air, and the carbs get all cold air, does anyone see any problems. Besides leaning it out a bit. Still have stock jetting in it anyway, so it's a bit rich anyhow.
Thinking about this post of mine. If the engine is going to draw pretty much colder air by blocking 1,2,3 or 4 of these ports off.........the engine should be running richer because the air charge is less dense because of the cooler/colder air. I am thinking right......aren't I????????
i bought a 1999 srx last year that draws all of its air from under the hood. I would get bog when im riding in deep snow and when i am carving exhaust pipe outta the snow. So i find it hard to belive that a exhaust deflector will slove the problem. I guess the frusterating thing is... if so many people have had issues with this, myself included why has yamaha not addressd it themselves.
my mountain max700 tripple rolled chain case 153 track really likes the deep snow but the motor boggs out so imtaped up the vents on the front of the belly pan and up front no more problems i run with the air box attached and holtzman temp compensator so jetting is allways right so im going 2 say something 2 do with under hood air pressure and possible wet wiring on ignition. it would cut out on 1 cylinder
