Hi i am currently getting a new end cap for my exaust wich increases sound and performance and it says to jet my carb if i get this, any one know how hard this is and how to do it ???? is it worth doing??????? all replies will be appreciatted!!!!!!!!!! thanks -Mark_

 

take your air box lid off too or atleast the snorkle. The new cap will give you hardly any noticeable gains, it might sound better so you think your going faster lol

search for carb jetting guides on google or something, there are a couple sites with full instructions and pictures.

 

definatly worth doing. jetting the carb will make a big difference. go to dynojet.com and buy the kit for your bike. it gives full instructions on how to jet your carb.

 

if your keeping the stock pipe and replacing the end cap and removing the air box lid ,a 142.5 small round should work fine
it would be a good idea to get a adjustable needle DJ is one of the most popular ones out there . the 4th clip space is were most have them set at
some day when you replace the whole pipe then you will have to rejet a lot bigger
jets ,165 main and a number 25 air jet
