Thanks for posting the before and after! I'm on the foc-uk website and found my way here after searching around. My top end has EXACTLY the same rattle noise and now I know what the problem is. I had the carbs out already last year following a long trip where I believe some dodgy fuel (and the original fuel filter on a 45000km bike) led to blocked pilot jets. It's all been a learning curve and I wasn't aware of the cam chain tensioner being under the carbs. I'll have to whip the carbs off again (they need bench syncing anyway) and I'll get at the tensioner. I just hope the chain doesn't need replacing as I think that's out of my skill level.
Dan Lucas Hello, im not convinced the cam chain itself if the fault going by my own experience. Id say its more to do with the tensioners. I replaced both while i had my fazer and the noise still returned and was advised to reset the tensioner once more to make her quiet again but by that time she was up for sale again. It does seem harmless but rather annoying to listen to.
ajls2 Yes I read that you replaced the chain in further posts. It might come to that as my bike is nearing 50000km. You managed to replace the chain without breaking the engine right? From reading the thread I see people talking about taking the cam lobes out, was that a required part of the job? I've done a few top end rebuilds now but never tackled the bottom end of an engine
@danielbrimelow Hi Dan, it cost me £300 at a private garage, that included the replacement of the chain, the valve clearances being done and the carbs balanced. Use a soft link cam chain if your gonna get yours done.. saves splitting the engine and the job can be done in the frame.
60,000 miles on mine. The only things that have caused problems have been cracks in the rubbers that go between the carbs and air box and some sludge from the petrol tank causing the carbs to need cleaning out, tank flushed and a fuel filter fitted. Other than that, just normal service items - bearings, chain and sprockets etc. My fazer has been ridden hard, track dayed, toured to Czech Republic, Italy, Spain. It's been more reliable than my bmw. The best 3 grand I've ever spent
@ilikejumpstyle usually valves tighten and you wouldnt hear any sound, it is most likely your chain\tensioner making the noise. If you have a good mechanic near you it would be worth getting amother opinion.
Some fazer engines seem to suffer from this.. it seems there is some slack in the cam chain thats taken out once the bike heats up and reaches its operating temperature. Advancing the tensioner one click often cures the noise and it can also disappear by itself through time.. General advice is as long as its not making the noise when its warm its nothing to worry about. Search google for fazer owners club, theres some top people on there who can also help.
You could but it would only be a temporary solution and isn't really recommended as all your doing is advancing it till it clicks once, but the adjuster should do this itself once the chain is slack enough to allow it to advance. You may find once it does advance the noise will be gone by itself.
I have asked the local moto-store, but they say it is normal, like many street bikes does this sound and there is no reason to worry about it as it is normal.It still would be a big relief for me if the tick would be gone on cold starting.. So can I just tighten the tensioner a bit?
Why is it so that my yamaha fzs 600 fazer is making a ticking sound when the engine is cold ( when I start it at the morning , for example ), and when the engine gets warm the ticking sound is gone? Can you help please ?
