Cheers kaw rider I am going to order one of these 30 psi caps and the semco hoses but also I am still going to try and install a fan. My mate has a bike shop here where I live and he is looking into a fan that Tuck posted to see what they cost here. Also looking at trials bike fans on Ebay as some of my mates have trials bikes and waiting on a couple of them to get back to me with the dimmensions of the fans on their bikes
