maskmanLS6 Posted January 28, 2013 Report Posted January 28, 2013 I measured the distance to the port floors from the top deck of the cylinders and got a measurement of 53.95mm. would that be a stock stroke cylinder measurement? Quote
maskmanLS6 Posted January 28, 2013 Author Report Posted January 28, 2013 So i can run a stock stroke crank with these cylinders, i already have a stock stroke crank and pistons and plan to put it together this weekend. Quote
sleeper06 Posted January 31, 2013 Report Posted January 31, 2013 Yes sir it's not dropped but are they raised at all Quote
maskmanLS6 Posted February 2, 2013 Author Report Posted February 2, 2013 What measurement would i get from the top of the ports to the top of the cylinder on an unported cylinder? Quote
maskmanLS6 Posted February 4, 2013 Author Report Posted February 4, 2013 The measurements on these cylinders were 41.275 mm from the top of the transfer ports to the top of the cylinder and 25.4 mm from the top of the exhaust port to the top of the cylinder. Is this a fairly heavy port job? Quote
skywalker7374 Posted February 4, 2013 Report Posted February 4, 2013 If its 25mm to deck from the exhaust port, that is a really really super high strung set up. Quote
maskmanLS6 Posted February 4, 2013 Author Report Posted February 4, 2013 It measured 1 inch which is 25.4mm from the top of the exhaust port to the top deck of the cylinders. Is high strung meaning a serious drag port? Quote
Pasi S. Posted February 6, 2013 Report Posted February 6, 2013 31mm ex 43mm transfers. I have one set of stock cylinders out of -87 J-arm bike. And Exhaust port is 30mm from the deck. LOL. Everytime someone asks a stock port durations, he will get 10 different munbers. Quote
