Received the new radiator today. I guess/hope it will make a difference. Bike is 20 years old. Probably still the first radiator. But very clogged/deformed cooling area. I think the length(lack of it) of the front fender is responsible for this. Thus the reason why I installed an extender.
Looks neat, together with the new collector 👍. Somebody allready had problems with the radiator? Oxidated/bad cooling?

Good luck with the install!!
Are you going to mount a screen in front of it?

A fender extender has kept my rads in decent shape, unavoidable a bit of crud in the center lower, but all good. Russ had suggested a yearly cleaning with air conditioning foaming cleaner..... a good idea, and flush with garden hose from the back side if you can. I had my rad off, and there were tiny stones and some tar build-up.... tried to dissolve with mineral spirits or naptha with moderate success, in the end just picked/blew the stones out and carried on. Be careful with straightening fins, use a toothpick perhaps. I hesitate using screens, don't want to cut down on the airflow.

Your old rad has seen better days, congrats on the new one.

The cleaning sounds like a very good idea! Will keep it in mind.
I haven’t found a screen yet for my Gen I. But as RaYzerman said, I don’t want less airflow.
So I put my trust in my extender : ).

I've run Cox Racing radiator guards on all my FJRs, as well as fender extenders. I live in Phoenix where it's quite hot obviously. Sitting and idling often such as traffic lights and i've never had an issue with overheating.

My buddy holed his 916 radiator and it cost him big time to replace it. Cox screens go on all my bikes with the exception of the RC51 which has side-mounted radiators. Never noticed any of these bikes running hotter but I was at first hesitant due to reduced airflow.

had a Cox screen on my 1st FJR...'03 ball burner...ran that bike almost 90k and sold to my nephew who still rides it...since it was touted as a Super Sport Tourer I stayed of the loup cruises and toured the US...saved the radiator many times from road debris and rocks...money well spent anf highly recommended
