Ouch, my eyes hurt now...Sentence structure and punctuation is your friend.
A 3mm stroker crank will basically drop right in, a 4mm requires the cases to be machined (trenched) to work.

A .040 over piston does nothing for perfomance.... overbore pistons are just for when you seize you top end and you need a re bore/hone, you must be thinking of a 240 big bore kit. I say stroker first get the ports matched and a nice port job, carb, pipe and advance the timing. Then later on when you have the cash buy a big bore kit.
basically to put in a 4mil crank you have to tare down your whole engine, send the cases to a machine shop and have them cut to fit a 4mil. its alot of work unless your building a full out drag bike, IMO i would do a 3mil, have it all port matched and good port done and it will fly.
it really isnt for the feignt of heart and you need to trench your crankcase and match the ports in order for it to fit/get the most performance out of it...im guessing you didnt try the search button? theres dozens of this exact thread lol
so a 3mm will fit right into the case i dont have to get work do on that but i still need to port what does that exactly mean im taking it to a regular machine shop incase they ask i dont know anything about that kind of stuff im trying to build it more for hill climbing not a fast drag bike but it would be nice to go faster
why do i need a bigger pipe i was told the pipe i had is the best you can get for the blaster and im really low on money im getting the stroker kit for xmas and the machine one for xmas i dont have the money for a new carb but how about setting up a different jets
oh ok but would you recomend getting bigger jets and new reeds i have boysing reeds or how ever you spell it and a k and n the fmf fatty with i think the 2 core fmf pipe im trying to make it have some more power more low end is fine im just pretty much climbing hills i just no nothing about 2 strokes its the first one i owned
Don't worry man, just use the search button and do some research, these tons of info here if you just look.
