Cam chain buzzing noise

[darrsi]

Just an update on this.


It was the cam chain along with the associated parts around it that were worn and needed replacing.


But just a word of caution for anyone thinking of getting this type of issue sorted in the future.
It really isn't straightforward at all, as not only are some parts hard to get, but one important part is actually discontinued as well.
I eventually ended up getting parts myself from abroad, but they are few and far between without a doubt.


To make matters worse, due to these bikes getting on a bit now the engine parts are not so easy to remove either, as I have just found out the hard way, resulting in engine removal.


Add to that, the damn exhaust header bolts get worse with age too so have also been a problem.
I "snapped" one a few years ago on removal, and when I say snapped it was like I was undoing a stud made of chalk.
And on refitting my exhaust my mechanic snapped one too.


All in all it's going to be an expensive and drawn out experience, but the reason I persevered is because I know the bike and everything else that's been done to it, so when I get it back on Monday it should last for many more years.

Epic faff. So it looks like you were right all along in your suspicions and were not imagining things.

Helped me out very quickly.

If parts are on their website they either have them or can get them, otherwise you won't see them at all.

Cost aside, they did say my pistons, valves, etc, all looked good, so my regular oil changes paid off, and the fact my cam chain has not faltered for 64K is also a sign of reasonable maintenance.


My bad, I overlooked this part of the engine, and I'm paying the price, but lesson learned.

[/quote]I don't know what maintenance can be done to prolong the cam chain actually over what you have already been doing maintenance wise. Other people on here have higher mileage fazers without any camchain issues wonder if it was a previous owner that have caused its demise

The previous owner treated the bike as a toy, it was in a bad way when I bought it at 26,000 miles.
It had clearly been used, abused and dropped.


As you all know by now my bike's mainly a commuter, so it's not like I'm out ragging it all the time, the chance would be a fine thing.


There's a bike on Ebay with the same mileage as mine, from a dealer, basically saying everything is great apart from "cam chain rattle at start up but goes away when revved".


Be warned, that noise ain't going anywhere else, it's not good news.

There should be laws about that the same as there are about cruelty to animals  :\

had 50k miles on the fazer I have and restoring it now. cam chain replaced and valve clearances done. all 14/16 valves were tight lol
but since then the first test drive was great, lots more power and the chain ticking is gone.
