I'm waiting to see if it's a problem, too. My 2007 FLTR was so hot I had to do a Stage 1 with a dynotune which solved the heat problem. I'm surprised that my 2010 with cats has not felt excessively hot yet. I bought it last November so it will be another couple of months before I know. It would be nice if I didn't have to drop another $1,500 to fix a heat problem on this bike!

 

So far I haven't noticed a heat issue, but then again I haven't ridden the bike in 100 degree air yet. I think that what we're seeing is yet another case of internet hysteria. I can tell you that my Night Train puts off more heat than my Limited.

 

I love it. Clean air you know.

 

These pistons are out of my 2010 Ultra and have only 500 miles on them. I know that the cat has nothing to do with the way these pistons look but thought that you guys might want to rethink what you're doing as far a exhaust systems and fuel management.

Another 2010 owner with under 1000 miles pulled his apart for a build and reported exactly the same thing!

Kinda shabby in my honest opinion.

 

Well said. I've ridden about 15 different HD touring bikes over the past couple years. Lots of rentals. And some were cat-less, some had cats. And I live in California so all our bikes have cats.

Really, the converters are not a problem. On a 100° day, it's the heat coming off the motor that fries your thighs. Not the cat. Traffic plain sucks at that temperature.

That said, I don't know how you guys live and ride in the 49 states that do not allow lane sharing. No way would I ride on the freeways if I couldn't do that. Bumper-to-bumper traffic would roast me to death. What do you do? Skip riding if there's a traffic jam?

 

Traffic Jam? Is that served with toast?

Seriously though, here in the east coast you would have to be in a major city during rush hour to get a full blown "traffic jam". All we see is mostly "traffic".
Also, the only lane splitters we have around here are either drunks or people running from the cops...

Does your builder contribute the scorched pistons tips from a lean condition?

 

I'd be curious to know the builder's opinion. My 'Train's pistons didn't look that bad, and that bike was bleeding oil through the valve guide seals.

Here around DC, we get traffic jams something fierce. I try to stay clear of the beltway in the afternoons, because it's no fun being stuck on a black bike at a standstill in 100 degree weather.

 

Don't want to jack the thread about 2010 cats but sure would like to learn more about those pistons. Wondering if that is what a stock 2010 motor piston looks like after 500 miles and if so, just how bad is that and should corrective action be taken?
