I putting on a ported cylinder and I'm thinking about installing a windowed piston and reed valve since it's already going to be apart but don't know much about them. Should I get a single or double windowed piston?
@@jaguars004 Sorry, maybe my question was not correct. Should I just use a permanent marker pen to draw a window on that piston's surface through the intake hole while the cylinder is in place? What position should the piston be at this moment? Or, maybe larger (more in height) window will be better? The more I search the more forms I see: www.picclickimg.com/d/l400/pict/172618957968_/66-80cc-MOTORIZED-BICYCLE-REEDVALVE-WINDOW-PISTON-HIGH-PIN.jpg cdn.shopify.com/s/files/1/2624/6138/products/27394062_575956106076491_1101105316_o_1024x1024@2x.jpg?v=1517007311 cdn11.bigcommerce.com/s-9pjycbbc8r/images/stencil/1280x1280/products/1323/1779/ENGJL-PKWDW__61692.1525297161.jpg cdn.shopify.com/s/files/1/1121/0508/products/gt90_ported_piston.jpg
Hey man I ordered a pocket bike off of minipocketrockets.com and they didn’t give me any tracking information. I was wondering how do I go about getting that and can I trust this company to follow through with my order?
I have a 40 cc 4 stroke pocket bike I'm looking to make it go faster do you know any parts not a boost bottle or anything to make it go faster something under 100 dollars
My "80" cc engine blew a hole in center if piston so I got a brand new one and the Windows are on the intake side its only four stroking any clues on y?
