I just bought an 03 CR 250 and before ever riding it I went all over the bike and while checking the transmission oil level I noticed what looks to be hairline cracks around the oil level check bolt and also around the kickstarter on the case cover. I'm not sure if its a defective part or are they just casting marks? I doubt if the dealer will stand behind it, being an MX bike, so I'm not sure what to do. Can anyone with an 03 CR check and see if your bike has these? Thanks
