We're kind of doubling back now - we've covered most of this. The tiny little "decorative" oil coolers seen today, if they perform any real function at all, only serve to save the oil from thermal breakdown so that it can continue to lubricate. Superfluous in a day and age when many appropriate oils have such high thresholds for such that the wheezing, underpowered engines to which these coolers are fitted will never reach that threshold. So this is where the marketing guys win the engineering argument - the customer expects to see an oil cooler as an indication of increased power and performance. The engineer knows it's not required. The customer does not. The marketing guy says to put it on - the "more powerful" bike "needs" one... nod nod, wink wink...

Consider that the new $9K HD cafe racer is a 750 water cooled twin with radiator and won't get out of its own way, made in xxxxing India too. Now I love Indian food and Mahindra tractors are great too, but an HD???

Does it surprise me that they put an oil cooler on? Yes Did it surprise me that they put a 1930s Indian clutch in a 72 AMF Sportster...Yeah. Did it surprise me when all of the hard facting in the 72 transmission was glitter in the oil in 10K miles? Yeah.

Did more research and found a claim that there were 240 1972 LT-1 Vettes with factory A/C.....engines were solid lifter.....another bet I would have lost to join the 1965 327/365 Vette with factory Air....

i never had much interest in Indians but hearing they used a wet clutch in the 30's got my attention.maybe that's the reason i never had much interest in indians?

I'm now left wondering if there is some reason I have missed about why a wet clutch is more desirable than a dry clutch ?

I have always just presumed HD gave up on actually trying to fix what was the real problem, sealing them off from the oil" and just took the easier option.

Yamaha with their race bikes went the other way. As they started to produce a lot of HP they went to a dry clutch. Seems obvious enough to me.

But maybe they just weren't smart enough to make a wet clutch work ?

The little TZ's need to slip their clutches for the first 50 yards just to get under way. You'd think a wet clutch would be perfect for that ! It's very easy to make them slip.

Oil helps to cool the clutch

Plus....if you get oil or grease on a dry clutch like in my BMW.....guess what

Us old Ducati kids wear tee shirts that say "loud clutches save lives". That distinctive dry clutch rattle used to be the hallmark of the make. Now, with increasing power, they've gone wet.

And do they have hydraulic clutches or do you have to have arms like Popeye The Sailor Man ?
