So im posting to ask a few direct questions. Most of my questions have been asked but it seems because there are so many different opinions, I cant seem to find direct answers. I am starting a new build, not my first build but it is my first banshee and 2 stroke build. I am starting with the engine and then i'll pick up a roller and go from there. This bike will only be the trail/fire road bike. With that being said it seems that the build most people go with the 4mil, cool head and ported cylinders. I have been trolling the forums and have noticed a bunch of different things that I should do. Shift star mod, pancake bearing, portmatch the cases to the cylinders, are the immediate ones that come to mind at the moment. Now my questions are, when I pick up a +4 crank from HJR, will I need to do anything specific to the cases? I know a few people have mentioned the rods hitting. I have seen people prefer the 115 rod because of reduced side load, but will I see a difference between the two? I am working on the just the bottom end at the moment but just need to make sure that what I drop in it will work with what I want to do on the topend. On the top I would like to go stock bore ported with coolhead and stock carbs. Thanks in advance for any guidance
