New to the ATV scene. My bro. begged me to get one. He has a 2004 yfz 450. I am pretty poor so I got a 1997 Yamaha Blaster last fall and I'm glad I did. Love to ride. Already addicted. Went on the trails up north on the last weekend they were open. Had a BLAST. Unfortunately my Blaster broke down at the end of the trip. Got a Manuel, flywheel puller, and my brother for help. Took apart the top end, just started cracking open the bottom. There's definitely up and down play on the rod. Don't know anything about it. I really don't have money to buy unnecessary parts. Any advice would be appreciated. I should already be riding. Please help. Have a fun and safe season. If you can mix those two? Haha.
