shipping them USPS is about the same price.
Wish i would have seen these sooner, i wanted to borrow/rent a set earlier this spring to compare to my r2's.
mine runs pretty low. if i top it off it just pukes it back out until it gets to where it wants to run. i dont run an overflow tank. hasnt overheated yet.
I dont know the technical stuff but this time around i built a pump gas engine and have been way happier with it, not to mention cheaper to ride. Its alot smoother.
too high or too far back there? mine would never draw coolant back into the radiator like its supposed to as it cools. ended up ditching it and calling it a day.
