I am looking for 2 calculations .
The first is engine bore and stroke to engine cc's. I tried my own version and came to 745cc. I think I may of got this wrong.
The second is a calculation that calculates engine rpm to rear wheel rpm. It's on here somewhere but I cannot find it. it goes through all the gear ratios.

Remember Bore is the full with of the cylinder but in calculating volume you need the radius which is half the bore.

bore is 102mm so. The the formula is Pi x 51 x 51 x 84

I use this may need to drop a few numbers in there for the XX but it works.
