Hey guys,
So before I get to my question, awhile back I had posted about my pannier flying off and options for replacement. So I bought a complete replacement on ebay and modded the hinge system. I did this on the other one as well. Here it is!
Bottom:
Inside, kind of dirty, I know:
On the Bike, can't even tell:
I'm not losin' another one of those things.
So now for my question(s): I also previously posted about it running hot. I've gotten it to the point where it runs consistently at a reasonable temperature, but it's still slightly warm. Based on this, I assume that everything is working as it should because the temperature of the bike noticeably changes with the temperature of the day. On a cool day, it runs cool. On a warm day, it runs warmer.
I was reading around on the forum and found a thread that mentioned the difference between the older and 'newer' radiators and water pumps. Apparently, the older radiators had a larger capacity and the older water pumps actually pumped more water at a faster rate. I saw a couple forums that mentioned replacing the 'newer' radiators and pumps with the older ones. I would like to look in to this.
-Is there anything I need to know, or is it just a simple swap of parts? I want to make sure that the older water/oil pump will fit right on the 16v engine.
-What year radiator should I look for? And what year pump, just pre-16valve?
-I was reading up on some of the older pumps and learned about an issue with the impeller nut coming off. Should I avoid buying that sort of pump?
-I also see a pretty big difference between the original cast impeller and the 'bladed(?)' one. Any difference in pumping power/force there?
Thanks in advance.
