[QUOTE="BSWIFT, post: 1416649, member: 16802"] The jetting links at the top of this forum is all you need along with a spread of jets. Follow Spanky's guide to the letter and you will have your bike jetted properly and be able to tell when you need to change for varying conditions and how you ride the bike. It is very important to start in the right place and make one change at a time. Insure you have a clean filter, fresh fuel, proper premix (regargless of the brand of premix), and no other problems. Your premix ration should be within the proper range of the oil. OEM's recommend 32:1 but many members run other ratios. I run 40:1 in all my 2 strokes and use my old premix for the weed whacker and chainsaw. Use an oil that is retilly available and in your price range. Stay consistant with your fuel and your mix. Most pump fuel varies so buy from the same place when you can. Spanky's guide works. Read it thru before you start and keep it handy while you are doing it. I jetted my YZ250 5 years ago and still run the same plug. Granted I have not riden much in 3 years but the bike starts 1-2 kicks every time. Good luck and have fun. [/QUOTE]
