Hey Dave,
I recommend you have your OEM radiator recorded (clean and rodded will not cut it, old core is not efficient even when clean) with the recommended three core which can be found in the cooling the Tiger article. Fan is another big item that you need to change. Again, go with the 15" recommended in the article.
This way you will not have to cut your Tiger for a non OEM part.
I have done everything you have + the core and fan and my car NEVER goes above 180 in any condition. I have a mildly tuned 260 bored .030 over.
Before I did all of this work, my cooling temp would rise to 240 while at freeway speed. I found that my radiator was 50% clogged. It would cool OK at lower speeds and idle.
