Description of 'pinking' required
Hello,
I am currently in Costa Rica on my way from Alaska to Argentina. I am riding a Yamaha XT225 and lately have noticed a funny noise every now and then. It is like a high pitched tinkling and usually occurs when I am going uphill or if I am in too high a gear for my speed. Someone has suggested this could be pinking but I don't know what that means.
Could someone possibly describe:
1. What pinking sounds like
2. What causes it
3. What damage it does
4. How to cure it
Thanks very much in advance to you technical people.
Cheers,
Lois
