Recieved ebay 1986 radiator today and with one extra row it has 8.3% more cooling seface. When trying to remove a threaded plug from the thermo switch hole I damaged the solder joint
and had to resolder
. After repairs I did a test fitup and everything is good. I also bought a small radeator from a VFR 750 at the wrecker, and am looking at how to add it to the system. The other option is to relocate the original 1983 radiator and run the coolent through both, this would be the best if I can find a good location. with 1.9 times the radiator area all cooling problems should vanish and the rejetting can procied, so that I can get close to the optimum 14.7 air fuel ratio and be in the 80 - 90 mpg zone. I am still waiting for the smaller jetting from Honda. I have also made a new undertray and will work on that tomorrow...
