Harley davidson 1953 Panhead engine

Really nice model of 1953 Harley Davidson Motor company Panhead motor. 
didnt desing myself, just make some changes to be able to print. Enough detail to scale the model till possibility of the 256x256mm printing bed. 
in original i had idea make it as secret storage for bottle in cylinders. which i quit later because it will be too big..  
if you will decide to print please be patient when removing the support in the heads and cylinders. but mainly the heads are really pain to remove support! and its quite fragile. it will be better to scale it up a little. for better strength. i just like to print for test to see if everything working as expected. No isue at all. 
I printed with PETg
didnt have any assembly plan, but i think that its a quite obvious..
