What is this about needing a special tool 7/16. anyone have a picture
of what they are (who ever are is) talking about?
Is it in a standard tool box? (novice)
If you have installed one can you describe the tool and such.
Thanks
I've been extremely happy with my 10 row vertical Jagg. I chose it because I thought it would be more efficient than a horizontal cooler - away from reflected road heat and less likely to be abused by rocks and other stuff that might bounce up from the road. If you don't know it's there and are not looking for it you can't see it blends in well with the black frame. Took some time to install it, but it wasn't rocket science. I choose to go without the cut off valve or thermostat - less to go wrong. In the winter, I let it warm up for a few minutes before riding.
I have the HD Premium that I've used through two summers in S. LA and have found it a very good cooler for our hot weather. It is an 8-row with "turbulators," like Jagg, but Jagg has a 10-row cooler that can be mounted either low like the HD or vertically along the left downtube. The HD comes with a thermostat, which I consider essential (or a manual bypass valve), and my limited experience with the Jagg t'stats is that they can be problematic. A friend bought one but the valve wouldn't open and the replacement wouldn't close. He gave up and installed a manual valve, which will work as well if you remember to use it.
I've never heard of a problem with the HD cooler and it cools effectively, so if I had to do it over again I would buy it. I'm running lean AFR's in the cruise range for better mileage and that translates into hotter engine temperatures, thus oil temps tend to run higher. In summer I never see >205° while the bike is moving >45mph and has never exceeded 230°, that only a few times in hot stop-and-go traffic. These are acceptable oil temps, IMO. FWIW I can also switch the PCV-AT into the richer base map on the fly for added cooling.
I personally feel that all TC engines should be equipped with oil coolers, especially the newer TC96/103's, and I wouldn't be without one on my bike.
I've got the HD premium put on for about a year without any leaks till I put in a PC and had it dyno'd. Brought it in to get it tightened up and watching for any further oil drools. Works pretty well till recently though.
