Mumbai use to be called Bombay. It is a very warm (hot) climate city with a population approaching 20 million.

The potential of hot weather and intense traffic is substantial. Not exactly where an air-cooled V-twin thrives. Think Miami with 20 million people.

 

Hscic has the same issue in Hawaii and fitted some cooling fans

Have you measured the temperature?

What part of the engine did you get your reading from?

How long was the motor running prior to measuring? (highway, or stop and go) (1hour, 30 mins etc)

Temperature of your location?

South Texas can regularly see days over 100 degrees and I have not had a cooling issue. I can even cover my oil cooler and the temp will rise but not to anything alarming.

Also, my sporty runs cooler in stop and go traffic than it does while on the highway.

 

Besides a good tune and all of the other good suggestions provided above, there are unconventional methods that work great.

Of course as bensonuk mentioned a cooling fan brings down temp perhaps 50-75 degrees in stop and go traffic.


Also one of the benefits of a Rekluse auto clutch is cooler operating temperatures which extends clutch pack life

 

why would you want to cool it down??? a motor that is hot on the outside is shedding a lot of heat, would you prefer that heat to stay in the motor??...a tune up to add more fuel to the mix might help (if it is not already correct)..you can buy some 'crotch coolers to help redirect some of the heat away from your va jay jay...or even (god forbid) come to the realization that you are sitting on top of the motor of the best motorcycle ever built and man up..

 

I totally understand the need to cool down your engine. I used to run 420+ in stop and go monitored by my Powervision tuner...there was nowhere to pull over for about 10 miles stretch so you don't want to starts pinging in that mess...better to take precautionary measures than have your engine seize. Spending a few hundred now will save you thousands later.

Everyone's situation is different so you need to assess how to best resolve your issue...

 

It's not the heat, it's the humidity.

Keep in mind the location of the sensor. It reads that hot because it is right above the combustion chamber. At least in the case of sporties.

With a sporty you need to monitor that head temp as well as the oil temperature to get an idea of how hot it is really running in my opinion.

 

One of my all time favorite bikes I have ever owned... never noticed it being any hotter than other bikes... also have owned 1200 custom, 1200t so as far as sportsers go i have some experience. Good thing you don't have a slim s!!! You really would think it is hot...

 

This is a rare thread... at least it seems to me.

I often read the Bagger and Softail folks crying about the heat (mostly on TC's). But, I hardly ever read of somebody complaining about heat on a Sporty.

I know on my own Sporty that's it's never been a problem. Before I did some tuning work on it, the engine (head) temps would often get into the 415 to 420 region. Since I've done the tuning (which fattened the AFR table up a bit), temps usually run in the 370 to 380 range on the hottest of days. Occasionally I've been able to get it back up in the low 400's when going up a slow stretch on a mountain road (35 to 45 mph). But usually it's pretty steady between 370 and 380. Imagine if I was stuck in stop and go traffic (try to avoid this if possible) it would creep back up into the low 400's.

I any case, I've never had a complaint because of the heat being thrown off by the motor on my Sporty. It's one of the reasons that I get a chuckle when the BT types tell somebody with a Sporty that they need to get a real bike. I laugh, and think to myself - "Ya, but you don't hear me crying like a whiny bi.ch about the heat."
