Getting my bike ready for a trip down to Baja over xmas. It's an 03 that doesn't have a ton of hours on it and was well maintained by the previous owner. starts and runs fine, lots of power, no smoke and it doesn't use any oil. I noticed last summer that when it was hot the compression felt a little lower when kicking it over. The bike never feel like it has a ton of compression, which I know is all relative and yes I know it has an auto decompression mechanism. Here's my question: should I be worried at all? I'm going to try and lay my hands on a leak down tester when I get home. I've only got a week off work before xmas to get the bike ready so time is of the essence. I'm going to check my valve clearances as part of my pre-trip tear down. I could MAYBE get the rebuild done before I left but it can take a long time to get parts up here in Canada and I doubt I would be able to get the bore mic'ed and a new piston installed within a week. Especially if I needed head work done. Am I being parinoid?
