I just recently picked up an '87 TRX350D 4x4. It fires right up, even with the kickstarter, but there is an obvious ticking sound in the top-end at idle. This ticking sound becomes a very loud tapping sound as the throttle is opened. I shut the engine off when I heard how loud the noise got at higher rpm's; it just didn't sound healthy at all.
Any advice? I'm new to four-strokes and could use some advice before I start an engine tear-down.
It seems like compression is very good and the valve clearances must be in spec or it wouldn't start as easy as it does. I've checked the cam chain tensioner and it seems to be working properly. Just looking for some guidance...
