[QUOTE="oldguy, post: 1408627, member: 16965"] We went from a 125 to 144 on my 2003 RM and we had to lean it out afterwards. I never really paid attention during the summer because it got very little use but for ice racing we now have a 450 main and a 47.5 pilot until the temp goes below 20*F. at that temp we jump the main up to a 460. I bought all the mains from 430 to 490 (go in jumps of 5) and pilots from 35 to 52.5 (jump 2.5) at the suzuki dealer for about $4 each When you start jetting make sure you have a new plug and a clean/oiled air filter or you will be wasting your time. also be sure to keep track of changes and what they do at certain temps and humidity. I tend to forget details so I write down the specs each time we ride, then next winter we will have a solid starting point [/QUOTE]
