I saw that the cam`s of the camshaft are misaligned with the Cam Followers

Yes; I've made a new camshaft with drastically longer cam lobes to solve the problem until I can design cams better. I'll upload it for ya today.

2019_10_25: Talked to the gang last night and I've got a list of changes to make. In an effort to make the engine as compact as possible I've made it too compact! I'm going to increase cylinder length and conn rod length by 30mm. This will provide adequate room for a longer valve stem and a decent sized spring to seat it. It also allows room for cam follower which is dictating other changes to the upper crankcase.

My Crankcase_Upper Mod file has it on both sides

If you have can you message them to me lease if you can

Corrected today; Look for Crankcase_Lower_Full_Scale_Ed_03.stl Bearing supports are not needed in the lower half as there will be parts that bolt to the underside of the upper crankcase to do this. The bottom has to be kept open as much as possible for lubricating oil to flow properly.
