ROFL! Seriously dude! Nice way of putting that in writing!

Calculate Engine Displacement The problem is that uni has 14mm Piston pin & ZMA piston has 15mm. So u need to put bush in piston which is not reliable & using a bigger piston will give a whole lot of vibration. Next is that u need to put ZMA sleeve & taking of around 9mm off will make ur bore thin & will heat up the engine nicely. So u need to use fully synthetic engine oil to keep the viscosity of oil. You can use ambition 59.5 mm piston which has 14mm pin & make it 160.77 CC.
