Do try to keep me posted on how well your 1200cc did down there and if there was any challenging in finding a premium fuel off the main road?
I had a 883 but converted it into a high performance 1200cc with Buell Thunderstorm heads, 10.5 high compression pistons, .536 cams, and it is chopper style so when I decided I would use the sportster from Deadhorse to Ushuaia I am now converting the motor again. This time I am going with 2004-2006 heads, and 04+ cylinder jugs, forged aluminum pistons, and a stock "W" cams. I will do a .030" clearance between piston and chamber on head so it can handle poor octane fuel. Kinda curious as to how your Sporty will handle fuel down there..
Thanks for doing the RR!
