Hi guys
I'm new to the forum but thought I'd add this.
I recently melted one of my pistons on my gen4, and basically a very long story short - it turns out the cause was a dirty fuel filter. This added load to the fuel pump which intern caused loads of crap with cylinder 4 (Cylinder 1 and 4 has different cooling routing so it's "hotter" than cylinder 2 and 3).
We have pretty poor quality fuel here in South Africa, but I just wanted to put it out there. Service that fuel filter every time you service you bike :grin2:
Also, I was told on hotter days, try not to go below half a tank of fuel since it adds to the core temperature of the combustion chamber..
The bike was a little lean at first, which I was aware of - after changing the filter and pump, not lean anymore...I'm sure a lot of you know this, but just in case.
I carried on and got the worst of it :headshake:
