Knocking sound
Posted: Tue Aug 05, 2014 7:48 am
Hello PCX peoples...
I live in the UK and have a 2011 PCXy which I love (the wife says I love it more than her... jury's still out!
)
I had the good fortune of having 2 weeks off in which time I didnt get any time to ride. I did take it out one day to my friend's place (about 40 miles each way) so we could do an oil change, clean the oil filter and change the air filter. After that we installed some leg guards on his Yamaha FJR 1300 and then went for a quick blast on his bike.. and blast is the word... man that bike FLIES... Awesome bike but a bit too big for my 5'7 frame so probably not something I would ever buy....
Apologies I went off topic there a bit... So yes We did the quick service bits and that was it. I rode back and didnt notice anything untoward. The bike was not used again for a week. As of yesterday I am back at work
Since yesterday I have noticed a slight knocking sound coming from the bike between 25-30mph on brisk accceleration. It doesnt occur on slow acceleration or really caning it but only at a very specific rate of acceleration on that little bit of the rev range. At the risk of ridicule, it sounds kinda like bongo drums (thats the best description my silly old brain can come up with). Its not loud but it is just about noticeable.
Is this something anyone has experienced before? I had a look on the forums but cant see anything... help please
