well I have the head off the 4k out of my old 55 and I had the head shaved and cleaned up a bit at the time so figured if it works too my advantage id use it
Hey guys I'm sure someone will chew me out for this but I can't find the info any where. Just wanting too know if a 4k head on a 5k will improve it or not?
:2thumbs: cheers for the help guys...but am now thinking bout heading down the kahanacross track insted so not sure if I will chase these rims up but thanks again!
