I went for a ride with a friend that has a 03'1000 2,500miles w/ a HMF full system and nothing else. We did some pretty hard riding and about an hour and a half his bike was leaking coolant pretty bad from the lowest center part of the radiator. It leaked alot more when he shut the bike off. I know some guys on this board have 1000s and I was wondering have they been blowing through radiators or this was just a freak of nature. any help would be apprieciated thanks
