I've been so motivated by this post, that I'm about to do a bunch of upgrades, though I'm befuddled by roller weights. I live up at 2000 feet in the mountains, and the main highway's at 3000 feet. My wife and I ride together, combined weight 260lbs. We're always going up or down. Down, we're topping out just below 70, and up, somewhere between 50 and 55 though we get there SLOWLY. We could use a bit more top end so people don't drive OVER us on the downhill, and MUCH better acceleration and topend on the uphills for the same reason. We're looking at getting a Dr. Pulley Variator (can't find naraku's at the moment), kevlar belt, 2000 rpm clutch spring, new jets (45 and 115), a dual flow unifilter, and lighter rollers...and that's where we're getting confused. We need to climb better, but don't want lower top-end speeds. The stock appears to be 13g for a 2009 Super 8 (though I could be wrong). Do we go 10, 11, or 12 gram and why? Thanks to everyone for this awesome string, and let me know if you have any other suggestions! Oh, also going with 35 watt bulbs to see if we can stop outdriving the lights. Our super 8's got 15K miles on it, runs like new, and we love her!!!
