Hello everyone, I just joined the forum and wanted to say hi. I've had my wolverine for a couple years now. It's a 2003, Black, And I put 25 inch mudlites on it with black aluminum rims. It's been a great four wheeler but I'm have some issues as of two days ago and I'm looking for some knowledge. What happened is that i got stuck in the snow and while pulling it ut with my other four wheeler my wife went open in reverse on my wolvy. I ran back to where she was spinning and stopped her but it was to late and now my motor makes a knocking/tapping sound. I'm wondering if it's a rod or maybe a valve of something. Any ideas? I've never torn down an atv engine. Are they a pain or not to bad? Any help is appreciated. Thanks
