Just under 500 miles. Warm sled up properly every time out. Premix in first tank....switch in ethanol mode... All updates done. Sled has good power from 0-60 but not as good as I expected compared to my 99 zr 600 efi. After 60 mph the power seems to drop off...however the sled will eventually reach 90-95 mph. The conditions were ideal -10 to +10 and hard & fast trails. Im not an expert & would think the sled is capable of a lot more. People are talking about adjusting the valve cables, throttle cable, adjusting the clutch, loosening the track etc.etc.etc....all of this tweaking to get the sled to run over 100.... If I had known it was going to be this bad I would have never bought the sled. To top it all off I pulled the pipe off yesterday & took a look at the pistons...noticed some scratches....WTF!!! I have babied this machine...with a full understanding of motor issues. My dealer is 2 hours away...hopefully he will get this thing fixed...without charging me an arm & a leg! Thanks for the help.
