05 450x....Literally stepped off the bike at about 1 mph in a really tight section on woods...turned out I put her down on a something hard. Crappy Works Connection braces bent inward and actually pierced the rad on the side...left rad....oh the irony. Well I've got some Unibiker cages ready to mount but I need a new radiator. Plan on getting the old one repaired as well for a backup, but for now what should I be looking at the replace the broke sucker with? OEM, aftermarket? This 'crash' is going to be expensive enough so some super fancy hi-flow rads that are $$ don't make a lotta sense to me. All I'm interested in is toughness and not having to dremel my bike into swiss cheese to get a fit. Best place to grab them online too while we're at it. To replace, I'm guessing it's simple as drain coolant, remove hoses, replace rad and top off coolant? Do you have to purge the air from the system? If so how do I go about doing this. I just plan on running a vanilla ethleyneglycol/water mix. I plan on replacing all of the coolant rubber hoses while I'm in there screwing around....should I just buy then precut and formed or would a generic roll of hose be just as effective? What gauge is the stuff anyway? Thanks for any info!
