i want some opinions on an engine build. i currently have an 05 bottom end with an 07 crank and the older style oil mod done to the cases. i have a 100mm nmotion cylinder to go along with it. my question is do i leave the bottom end alone and run the 100mm cylinder or should i put in my 6mm long rod stroker crank and go with a 98mm jsr tall cylinder? i know there will be alot more added cost putting the stroker crank in but im sure the power will be more also. i also want something that will be reliable and that i dont have to be into all the time. again voice your opinion on what i should do because im undecided. i do all types of riding so its not just a drag bike.

I would ask this question on YFZ TECH, they know their stuff on getting a fast reliable bike



If you do end up going with the storker crank make sure you get the crank balenced for what ever piston you plan on running. Without the crank being balanced you might get some serious vibration

Just my thoughts.
