Just installed the hot cam auto decompression exhaust cam for my 2000 YZF426. I measured the valve clearances and they were good. I put the bike together and it fired right up but I can't help but notice the ticking. The cam chain seems fine. I haven't romped on it yet. It idles and runs ok but I only took it for one lap around the house. I'm calling hot cams tomorrow for info but what do you think?
