1997 XLT 600 Triple. I changed the Primary spring to red and the weights to 10m blue. I changed the secondary helix to the one I found listed on this web site (can't remember the exact numbers right now. I think it was something like 38-43-36 but not sure). Sled now gets off the line perfect but it idles around 3500 after you ride a bit and it tops out at 8200 and about 65 or 70 MPH. What is happening? Is it running out of fuel? What do I need to adjust to bring the top end performance back up there?
