Hello, i have a 2007 polaris outlaw 525 irs and took the plastics off today too ajust the valves and noticed a crack on my cylinder head right along top were the timing chain sproket is. I dont think its cracked all the way through because its not leaking any oil. Well my question is i had a big riding trip planned easter weekend to haspin acres in indiana and want too know if i can put some type of jb weld on it to give me some time just for a day and a half ride and after i get back get a new head so basicaly will a type of jb weld give me some time? thank you

 

This is something only you can decide! Probably if the crack isn't that big and you don't think it might expand,them maybe JB weld or something similar might hold,but again it's your call. There are places that can weld aluminum/magnesium and may be able to solve the problem. Just call around.
