I overheated mine a bit not to long ago, melted my cam shaft sensor and damaged my head gasket. replaced them both and everything was fine. I'm curiouse to know what they said is wrong with yours. If anything you should be able to repair it yourself and save yourself a grand in lablor.

Do you have a remote oil temp guage?
on the hard tail the oil tank filler is visiable,, bdm has a temp dipstick.. you can lean over & look @ the oil temp in the tank..now on the mastiff I just bought you really cant tell.. I haven found a good way to install a temp gauge on it yet..that looks cool..

I did a few years ago, got caught in a parade in Philly. Bike got so hot I toasted the oil and it started blowing thick blue smoke, like smokescreen type shit. I changed the oil to synthetic and put some amsoil additive in there, and added a flow-through temp gauge from CAS-4. A week later my cam sensor went but no other problems. When I took my engine apart last year it all looked good. To my knowledge, CAS-4 is the only flow through temp gauge out there.

Mine never got so hot that it smoked. It was 3 years ago and it made a noise when I shut it off after being in Laughlin in the heavy traffic.
I'm being told new pistons, bored and rebuild. crank has .006 end play.
They are saying it looks like a piston tried to stick.
Motor seemed fine and used hardly any oil.
I only took it in to have new heads and a cam installed. I'm going up today to see for myself. I was surprised to say the least I'm at almost 18k on the engine

The Marlin Corporation makes a cylinder mount temperature gauge that measures head and oil temp via sending unit. Here's the link:Marlin Corporation
They make a nice billet single mount for a tem gauge and a dual mount for temp and oil.

Sorry, the website was always crap but hell it's gotten even worse since I last visited. Check here...
Oil Temperature Gauge for Harley Davidson
Be advised, this thing will break in less than 2000 miles. The top of the gauge will break from the vibration and just spin while the needle stays stationary. The fix is to glob some black RTV around the underside of the thermometer. I went through 3 of them before I figured this out. It's been good ever since, I've got about 15k on it.

I don't know about that thing, kind of looks like a cross between a turkey thermometer and a sink faucet knob.

well I went and looked at it today. It wasn't pretty.
Rear piston sits noticeably in the rear of the cylinder. when both pistons are brought up they both can be moved back and forth in the cylinder and the rear piston can be moved at least 1/16th. They took the rear cylinder off and the scuffing was ugly on the back of the cylinder. Piston skirts are all scratched up. There are tiny specs of aluminum embedded into the piston skirts
Looks like it's a full rebuild and balance. Crank is being sent to dark horse.
Don't know what caused this but I can't imagine the cylinders were very good to begin with when you can move a piston like that.
I called S&S today and they said 3k for a rebuild and a good 2 months plus shipping.
I'm guessing I'll be down for 3 months

Just curious, did you have any piston slap or noticeable valve train noise before this melt down?

I did have valve train noise but I think it always has. I did think it was getting a little worse. I have short pipes that are loud so that may have hidden the noise some
I talked with John Sachs today and he told me this was probably piston slap and a lot of people think it's valve train noise. When I switch to Amsoil and added the oil coolers the motor did quiet down but that was at 5k miles which was right after my Laughlin trip
This motor used hardly any oil and seemed to run fine. I would never have believed the damage if i hadn't seen it today. Hell I calculated my mileage on the way to this shop and it was 50mpg
I'm guessing the engine was overheated in laughlin 3 years ago but I don't think that explains cylinders loose as a $5 whore. This bike was never abused, no burn outs and oil changed regularly.
Both S&S and the shop that is doing the repair said it is very easy to over heat and damage one of these engines in traffic that isn't moving at a bike event.
I don't know that over heating is what caused this but the shop doing the rebuild thought so and said it looked like the rear cylinder tried to seize up.
