lms1977 Posted November 19, 2013 Report Posted November 19, 2013 wont the shorter rod help on the motor feeling snappy, with the longer rod they seem more lazy on the shorter stroke. it might have just been the combo thou. Quote
m671054 Posted November 19, 2013 Report Posted November 19, 2013 The 125 rod puts it at 1.95 rod ratio 115/64 stroke is 1.79 stk motor is 2.03. stk stroke long rod is 2.13 you decide. calculate the rpm you want to run and make power at then figure you piston speed. i bet you chose the 125 rod.

dozer Posted November 20, 2013 Report Posted November 20, 2013 (edited) crank works no longer sells a forged 10mm due to the amount of failures they were having (info from joe at crankworks). the billet one they sell has a larger center pin, 30mm vs 25 and i believe hot rods rods. tdr has a forged 10mm with 10 ball japanese bearings all the way down it and hot rod rods with a 25mm center pin. he also sells the crankworks one. just passing the info.

trickedcarbine Posted November 20, 2013 Author Report Posted November 20, 2013 Thanks guys. Gotta dive in to rod ratio education now as well. Quote
dozer Posted November 20, 2013 Report Posted November 20, 2013 interesting Dozer.... I bought a forged crankworks 10mil crank for my 10cub. from when I did my research a few people actually prefered the forged cranks vs billet. i was gona go the same route, forged crankworks. then i called them and they told me they no longer sell them because of failures. i know sprinklerman hasnt had any problems with his. the tdr forged one sounds like a good option too.

sprinklerman Posted November 20, 2013 Report Posted November 20, 2013 good to know though regardless! mind you im not too worried! most guys running 10mil's are running big compression / high strung set ups that tend to be tougher on a 10 crank.. my set up should be pretty cozy for the crank... lower comp (150ish) .. lower timing (4) etc... i know stuff like that makes a huge difference on engines and their duration of life Haha. Now your just trying to convince yourself you won't have a grenade on your hands.. Quote
sprinklerman Posted November 20, 2013 Report Posted November 20, 2013 ...not worried about a little jinx now are ya? You always have GREAT luck with banshees! Quote
sprinklerman Posted November 20, 2013 Report Posted November 20, 2013 . ...Loser. haha. Just install it right and run that thing! If it breaks, it breaks. They make more. Quote
