Porting

Alright lo i was about to say im outting all this money in it it better do something. an im runing either 18 inch or 20 inch mudsharks i think there actually 18 im not sure i plan on buying a new set so i didnt pay much attention to em there kida just on there for now an yeah i like my trail riding more ill use the 13/40 tooth. Im also looking for an exahust theres a kinda beat up fmf gold series for 100 buck no silencer online

lol nawww. i run MX and 18" with 13/40, and i find myself running out of gears a lot, and i dident have my cylinder ported at the time lol. but if u trail ride a lot, id go with 20" tires and 13/40 like u said. that thing will rip! also idk if this is complety true, but i would get the pipe first before you port. porting on a stock pipe would suck major.
 
just did that an alright so i dhould get a new pipe first huh?... is my stock carb gonna be enough with all this? obviously rejetting will have to happen

yea. stock carb will/ should be enough. and YES jetting should be changed! haha. later u can upgrade carb to like 28mm or something like that. i would use stock carb, jet it correctly and see how er runs.
