Sooo I decided to take my chances with an ebay one. Bad idea. It was one that looked like this: Lasted about a week, from 'carpluz' (from hong kong)on ebay, $37 US delivered. Bit the bullet and bought a genuine one - RRP $220 - ouch.. but got it trade for $193. Funny enough, looks like the aftermarket one above but thinner - i guess thats what they copied it off. Bike has run perfectly since. Seller has agreed to a refund if I post back to hong kong, so not all bad. Moral of the story, just be wary when buying these aftermarket regs.. even if they are so much cheaper than genuine. Ive heard of some after market lasting many Ks, and some not working at all. Mine did about 250Ks.
