Not to be one to crash the 600R party here, i love em but my 23 i sold at 8000km blew up the top end the other day. He mighta put 2000km on it not sure. So at 10k they are due for a rebuild. Feel bad for the guy but i paid 18 out the door and sold it for 8500 i think.
The machines new or old parked outside shoulda stayed parked on saturday morning at -37c. Nothing good happens at that temperature. Seen a few clubs fighting to fire em up and its just pointless.
