i would like to run clear coolant hoses for my engine. i have been to the website that claims there the only company that makes them, they show a fourstroke engine. i was wondering if anyone has tried the clear pvc tubing with the nylon wraping inside? i saw one 250r that had that line on it but cant remember where i saw it, i just want to know if they rate tubing at lower than it can actually handle like they do on chains. say a chain is rated at 2000lbs it can really handle 4000lbs. thanks brian.
