i just sold it. i have pics if you want some though
now to answer your question. I was runnning 36's and 5.43 gears in the rear and i would max out at 65. that's around 3200rpm. if you want more top end, you have to gear higher which is numerically lower. Then you start to bog down that 2.5. i ran the 2.5 with 34's and 4.10 and my low end ******, especially on the trail. i could get up to around 70-75 in it but that was the pedal to the floor in 4th gear and running around 3K on the tach. basically your speed problem is that motor and you're not gonna ever be able to run past 80 in it doing bolt on mods.
