I recently put my beloved bike in for a service and came back with the news that my bike ticks loudly under the seat where my fuel is when i turn on my bike. I know its normal for this model... but its very loud. I was told it was my fuel pump... but then i read on the trusty net that it could be my carby, fuel line, battery. I really dont want to be fixing one thing and finding that its not that and some thing else. Does any one know what it could be???? and does any one know how much a fuel pump part is... i was quoted at $150 upwards to 300?!
