If you're bike is running good in all ranges, and you are modding the carb, only because of something you read,......good luck ! You won't be the first to get into trouble by throwing mods at the carb w/o an obvious reason to do so. As was said, determining the mods a carb may need can depend on many different conditions.
Statement 1: Thank you. This would have sufficed.
Statement 2: Unless you're illiterate, I can safely assume that if you modded or will mod your bike, you probably modded your bike because of something you read as well. People here suggest 155main and 55pilot. I read that. I will be doing that based on what I have read. Therefore, I am modding my carb because of something I have read. Thanks for good luck if you did not intend irony.
Statement 3: Again, unless you're illiterate, my reason for modding my carb (as mentioned in OP) is because I will be replacing the intake and exhaust with the most free-flowing, tolerable devices available, seeking maximum power and acceleration. This reason is obvious because it is clearly written in the first post. Therefore it is an obvious reason. Therefore, I am, indeed, modding my carb with an obvious reason to do so.
Groupus, THANK YOU! I will seriously consider that.
To everyone else, thank you for your contributions from experience. It is exactly what I was looking for. It is always great to have a good source of information about these issues. I'll get the 155 and 55 jets and half spacer. I'm about 100 feet above sea level, so this should be more appropriate. I'll also do the carb tuning as Lancer suggested in the Tech section. The one where you unscrew the pilot screw until the bike runs better. (start at 1.5 turns, turn in and out as needed etc.).
