I have one, but its the venture, lots of mods but none power or clutch wise, with the exception of Iridium plugs and Vforce 3 reeds. Look at my sig for all the stuff done to it.
Performance wise, so far since iv owned my GPS, had 125 on it with a decent run and the speedo was readin 135 or a little closer to 130, but iv seen speeds over 150 on the speedo but havent seen those conditions for a while. Racing my friends (formula 583, ZL500, two polaris indy 500, and a 488 fan polaris and yamaha exciter, I smoke their @!#@$ until the very end of the lake. Havent got a reading or length of how far I hold the lead until anyone catches up but it is near 10 seconds at least, and they are studded as well. My sled also has 16000 kms and never rebuilt or had any problems at all, super relaible.
Im looking to mod this sled next year motor wise and buy a spare motor just in case something happens to this one with the mods. Simple swap and keeps me riding.
2001blue SXR, can you please elaborate on the mods you have done to your 99, it is so rare to have someone else mod this sled.
Also, if anyone wants to post pics, go ahead. I would gladly do also but I cant put any of my pics on this site, even after reducing the size so tiny. Always trying though
