Bought the bike new for 5600 from OTD motorsports First ride: Blown fork seal result: fixed under warranty Second ride: Welds holding chain guide to swingarm failed, sending chain into case-saver, breaking one case saver mounting post, destroying chain in the process. result: Yamaha "Good willed" me a new swingarm, but I still had to buy a new chain and case saver, and had to fix the case saver mount myself with JB weld, because Yamaha wouldn't help. The bike was not under warranty at this point, so I guess I can't complain. Third ride: Had a blast, went to change oil afterward, oil came out same color as off-white paint. result: unknown. Hopefully Yamaha will help, but bike is way beyond warranty. There's a blown gasket or seal somewhere in my motor. Right now I am kicking myself for not buying the extended warranty. I'm afraid to ride this bike anywhere now. Thankfully I have a 2005 yz250 2 stroke that works every time.
