[QUOTE="NO HAND, post: 324719, member: 18937"] Yeah eh? It's quite crazy the difference in jetting. I don't know what to think. The only thing that wasn't stock was that I put on a 01CR250 rubber airboot. It would have been such a pain to un-glue it again and test both airboot back to back. I can't tell if it's a step backwards or not. :eek: But what the heck. It was fun putting it on :confused: . To be honest, when I was comparing both airbooth in my hands, I had to look at them for like 10 minutes before I could notice a small difference in shape. I guess that is such a small difference that it has no effect on jetting. Oh, the other thing that isn't stock is the powervalve spacer. I measure to have 15mm of p.v. hanging out in the closed position(measured in the longest point). That forced me to use a 9mm pv spacer. I didn't do yet the Boyesen style PV mod. I was thinking about it and I plan to try it. I have to prepare myself psychologically to grind off that much material off my pv. Was it hard to do? I don't have much info on it. I just have a picture. Do you know someone who would have drawings or more precise specs? I would definitely give it a try. [/QUOTE]
