Ok, I've been reading everything I can find about the carbs on my bike. My bike is bone stock with a K&N filter and it has about 25,000 miles on it. Im confused about what mods I should make to the carbs. Im not looking for more power or anything just quicker warm up and a smooth running engine. Ive read all these articles and posts about #20 pilot jets, 10 cent rejets, drilling out brass plugs to get to some adjustment screws, etc,etc etc. I just want know what mods are the easiest and what actually should be done, and what can be done without removing the carbs. Thanks, I just want a clear answer as to what i should do, and like I said im not looking to mod the hell out of this bike.
