Okay, I just got back from the track with my project bike. I didn't update my thread, but it's a sampling of the "standard" gstwins.com upgrades: 0.9kg/mm springs, Kat600 shock and rear wheel, Pilot Powers, lunchbox, rejet, 1/5 throttle. Holy hell that's a good combo. I think it was Alpha's jetting numbers, which were right on, I didn't have to fiddle or adjust anything. It eats the stock GS for lunch.
Thousands of thanks to all the sarcastic bastards that have added to the general knowledge of this bike. There's certainly no way I could have ever built such a track eater on my budget without the knowledge of this forum.
yeah...i have to agree. I don't have a track bike, but the mods I have done have been great and it's been this site!!
