I live in Alaska and I fucked up. I bought an 08 ds 450 and it ran great. I checked the oil. I Rode 2 stroke dirt bikes my whole life and only worked on cars and sleds. So long story short I was ignorant the cold checking and over filled it. Now it won't go into gear even the the trannt cycles perfect. . How do I fix it. There's not alot of info on it. Besides bearing issues ok rode it for maybe 10 mins
