Hello! New to the forum and new to a Grizzly. Just got an 09 Grizz 350 2wd. Guy said was sitting about a year. Well I got it to putter a little with the pull cord and starter fluid into carb. So I bought it. I took carb off cleaned it, but it back. Checked oil, haven’t changed it yet. Oil wasn’t black, still looked pretty new. ATV looks to have no mods at all, still has stock tires. No hourmeter/odometer to know how much it’s been rode though. Using the pull cord is ridiculously hard, Amazing compression? So that fixed it, it fires right up with no choke and idles fine, revs up fine, gears are fine, engine feels tight. But after 15-20 minutes of riding I looked and oil had pumped back into the air box so hard it came out the side of the box and was running down onto my left footwell and down that side of the engine, and air box was 1/4"+ deep in it. Sooo… I let it cool. Check oil, it’s now so low it doesn’t touch the dipstick. (checked without screwing it in) is this right? I then topped the oil off until it touched the top line on the dipstick without screwing it in. Then I took the breather line from air box to head and made sure it was nice and clear and it wasn’t pinched. I cranked the motor and covered the crank vent on the head. Can feel air but it’s light, pretty much the weight of my finger can seal it off, and I let it idle about 5 min and not a speck of oil came out that I seen. The pressure felt about the same as my Timberwolf 250s vent to me. So shouldn’t have blow by, compression feels GREAT. I refuse to pull start it it’s so difficult. Is there a compression relief valve for this thing? It has never smoked once, when cold or hot, at high rev or anything. When I idle it with no air filter or lid on and choke maybe 1/4 way on now and then I’ll get a very faint back fire, but figure that’s about normal with the lack of filter and choke on. What you guys think? Needs valve adjust? Timing? It sounds good. I’ll check these things tomorrow. Also spark plug was good. A dry and clean plug with a light rusty color.
Anyone got a link for a download of a service manual for one of these? That would be helpful.
