I'd use a stethoscope, well, screwdriver, tip against engine, handle on bone in front of ear & then in the ear, too. Top left on the engine, to see if the valves are claching a bit. Then, on the right side, too. See if you can hear clicking. Whirring is normal, because the cam chain slides on the guides. After you've listened, I would still open & look. This will allow you to gain the experience of having heard the sounds & seen the mechanical parts that make those sounds. IF the noises arent good & you open & see it in need of maintenance, then, you know what it sounds like when its time for work. If it sounds okay & looks okay, then later, if it starts sounding different, then its time to look again. Likely time for a cam chain. Dont pay someone else. Buy the tools, get thew book & we will talk you thru. WE? Yes, I just volunteered these others to help you, too. If you pay for the maintenance this bike needs, you will spend more than the bikes worth in a few years AND, your riding season will be spent with your bike sitting in line, waiting to be worked on. Most of the tools needed can be "El Cheapo" tools. My allen wrenches are from Harbor Freight, never stripped any. The cheap torque wrench from Sears is doing me fine. Looking at the torque specs, the bolts are to be torqued to any number of foot pounds, between 7 & 12( I think thats the range for the header studs) & looking at the manual, I noticed the range was wide on all the stuff I expect to ever touch, so an inexpensive torque wrench should do it. If you arent very strong, then for just a few bucks, an impact wrench, I have 1/2 inch & 3/8ths, a cheap compressor, just a small one to use to break nuts loose, will make it easier on you. I was able to reinstall the clutchpack without a backup holding the engine because the impact would run the nut home before the engine would spin. Must have worked, that was about 4,000 miles ago. All in all, this is a crude little bike, simple & forgiveing. Dont be afraid, wade on in. I was skeert, even tho I have a good mechanical background, but these folks talked me thru & just paying the labor on the cam chain would have cost me more than the price of the compressor & torque wrench.( I think, anyway)
