Hey guys, I REALLY want more power from my sled this year. I dont have 3000 to just blow on a sled and then go through that. Plus I love my ZR 500 so much that after the motor blows I'm going to but 600 jugs and pistons in, but anyways, I need help with performance options. Whats out there to do to this thing? I know clutching and I've been looking at a few different companies, what would you guys recommend? Can I put reeds into it also because its a efi sled, if so what brand? And the BIGGEST problem I had with the sled the last time I rode it was when I was cruising and then hit 50-60 it just bogs, backfires, and won't let me get over that until I let off the gas, let it cruise and then give it gas and most of the time it runs great again for about 15-30 mintues. It starts up first-second pull and idles great. I found out that my clutch spring was broke in half so I replaced it with another stock one and got all new bushings and things for it and put that back on about 2 months ago and it doesn't take a second to kick in now, so I hope that was the take-off problem I had last year. So guys please help me get more performance out of the sled. Give me websites or even guide me on the site to this stuff cause it's taking me awhile to just look around on here to research information on here, SO MANY FORUMS, thanks for all the help and information guys.
