Below shows one of the possible approaches to the treatment so that in my opinion it was the hands and feet. You can take a different course, there are no strict rules. All downloads are below. For those determined there will be nothing to jump.
Word access - to the conversion to 300 are suitable only without combination of ET cylinders 250 due to the angle of the exit window which the recess 75 does not change its position significantly. When the diameter of the recess on the fire ring disappears and the piston at TDC of the cylinder liner extends its height. The project is part of the head into account.
The most important element is necessary to rewrite the head:
1) The volume of the combustion chamber must be chosen so as to keep the compression ratio of 10.5 - 11: 1 while maintaining squich distance from the bottom of 0.9 mm. Chamber volume in the traditional way to measure the syringe with the liquid for assembled engine. Often I meet with the measuring head on the table capacity. This is so abnormal that it does not take into account the curvature of the bottom which is not flat.
2) Cat squish area, pull out of the up, so that the angle formed between the top surface of the head and was a divergent 1 - 2 degrees in the direction of the combustion chamber and not convergent. The diameter of the surface must be at least equal to the dimension of the piston, ie 75.5. I did continue to the next cut was good.
3) the ratio of the areas is proposing to do - squish chamber 60/40.
4) alteration must manually start the match Squish, since the dimension of 0.9 mm, it is very important for the performance of this type of head. It is only matched by Squish dremlujemy having a chamber to obtain a distinguished capacity.
Cylinder:
Without philosophy. In my opinion, it is good to take a ring of fire, because in a system where the engine hangs on the head once, and it helps the two centers the head is always in the same place. edge proposes leave sharply. This will facilitate the production of the seal by tightening the screws with a sense of the seal ring 250. The sharp edge will cut beautiful album of aluminum and have gicio równótką seal after the removal of cut waste. Luz ALMOT piston assembly (Hall) 0.05 mm. Honować cylinder to give a thick dimension stone. Then you need to do a rock intermediate 2 - 3 jumps to alignment inequalities that will plow the ring. Between the cylinder and the head is necessary to give even one aluminum pad. Motion below assumes that the most typical after inserting a 0.5 mm should appear 0.9 - 1 mm gap.
Dwg file I threw a few drawings from comments. Geometry is the curvature of the bottom and the same head 3d, taking into account all the above-described. Using a model of the head of the design height of the fire ring must be performed on 1.5 mm. His average external +/- 79.80 mm. This should be from the machine and the ability to process a circle into segments. (Turning it regards not the case here) People in the subject will know what it is, and here it is not important. The head is to be included on the ring that hides inside.
Well, that's it, here are some photos of the comment and the necessary materials. If there are any questions, feel free.
The probe must be placed on a table so as to maintain the parallelism of the table in the vicinity of 0.05. You can safely do so properly by placing plates of different thicknesses
