Hi folks, Just re-shimmed my exhaust valves recently, the bike was fine afterwards for a while but now makes a distinctive and fairly loud ticking sound which seems to be coming from the top end. It seems louder if I put my ear up by the rad (from the front). I don`t think it`s the MCCT and wondered if it could be to do with the valve springs?? It`s a bit louder than the soft tick of valve clearances. At first I thought it was the exhaust blowing from a bad seal at the head, kind of sounds like that, but the exhaust gasket is new - I replaced it hoping it would do the trick, but didn`t work. My bike (2005 DRZ400S) has an Anthena 440 kit, MCCT, hotcams stage 1, FCR41, MRD/SSW and so on. Has 22500 kms on the clock, about 7000 since the big bore. Will check the valve clearances again (did it when the engine was cold before) on Friday. Re-shimmed it to the hotcams spec. Any ideas??
