Yes I am clearly mad.
To maxhag - its called carbon build up. I'm not going to polish them, but I'd say 'great condition' is not entirely unreasonable seeing as THEY ARE SECOND HAND. Shit are you expecting second hand pistons to be polished at a price of $37.50 per piston ?
And to the dude in Netherlands... really? You want me to ship some second hand pistons to you from Australia? And your're not a scammer? Let me guess - you will paypal me the money, then pull it out 24 hours later, or wait no, you will hit me up with some bullshit merchant bank thing where you pay me an extra $240 into my paypal then I just pay it back to you via a convenient off shore untraceable account. Yes?
Look ppl, if someone has a bigport 4age they want to boost. These are the cheap man option. If not, whatever, they are just sitting in my cupboard. All good.
