If you were getting a true 95 mph with a Savage, you were doing right well. I would want to verify that speed with a GPS or a stopwatch before I believed it.
I was ridng that stretch of Hwy before wih my brother in law, who has a Nighthawk 750, and we were going about the same speed. He verified 95. And we were flying past the cars in the right lane that were going about 75. We often ride together, and of course at times you wanna know what goes. It always amazes me how hard it still pulls, like being behind a car in the right lane going 75, and then pulling in the left lane to pass, cracking it open, and all the sudden you're doing 90 already, and then it starts creeping towards 95, but eventually gets there. And that stretch of Hwy is flat, not downhill. It has no trouble maintaining 85 at a tad over half throttle. The bike has a gutted stock muffler stock 52.5 pilot and stock 145 main jet and a 2/3 spacer made out of 3 washers fron Lancer's jet kit. I had the other pilot and main jets in the bike, but it was running WAAAY rich, so I put the stock stuff back in. Idle mix screw is at 2 1/4 turns out, which is her sweet spot after lots of playing with it. Roll on from 40-70 in top gear is 9-10 seconds, verified several times. For almost stock, this performance is great. Others had to do alot more to it to get there. It even has the stock air filter in it.
