JETTING QUESTION???

I just bought a 1993 900 and in the process of cleaning the carbs i noticed that the stock jetting was in the bike. The bike does have a uni filter and a d&d slip on. If any one would know what to jet the bike without buying 5 diffrent jet sizes it would be very helpfull. I do know how to check plugs for jetting and so on... but would like a good starting point (2 sizes up 3 sizes up etc..). Thanks to all that reply!!!!!

Man you don't ask for much do ya Are you planning on changing the needle also or just bigger jets? If all you intend to do is change the jets then I'd go up 2 sizes -- I'd also get rid of that crap filter and go back to stock or go with a K&N or BMC street filter. If you go with the aftermarket filters then start out 3 sizes up. Now if you go the needle and jets route then you'll just have to follow the instructions. Since the aftermarket needles are so much thinner (EPA -- who needs EPA) I've actually had to go down a couple sizes when jetting. The thinner needles flow a lot of gas.

Good luck.
