http://youtu.be/EDqI1mgtiRw Along the lines of Hughlysses and Skifastbadly, I started to tear into the engine. Not too far, but plan on about 2 hours a day until done. (Message edited by rdkingryder on August 08, 2011) (Message edited by rdkingryder on August 08, 2011) | ||

So far, only gotten the exhaust off, some of the engine mounts, disconnected the harness. Still need to remove the idler, rest of the mounts and drop the engine down so I can disassemble it for further inspection. Hope this doesn't costs a small fortune.   | ||

Ok, weird, I am having trouble posting pictures. Ok, got it.  [IMG]http://i103.photobucket.com/albums/m135/rdkingryder/Ulysses%20Mods/UlyssesEngineWork005.jpg[/IMG]  (Message edited by rdkingryder on August 08, 2011) | ||

I would modify that cali-canister for hiding stuff in. | ||
| Teeps |
The canister, though agree is ugly, does keep fuel smell out of the garage. An important feature for folks that live in houses with attached garages... | ||
| Rr_eater |
Mines gone for years now, attached garage, no fuell smell, prettier bike for it. ONLY time I smell gas, is fill up and go straight home (about 3 miles). Dont do that, and no gas smell in the house!! Just saying, YSMV Bruce | ||

Ok, dropped the engine out today, not too bad really.   http://i103.photobucket.com/albums/m135/rdkingryde r/Ulysses%20Mods/UlyssesEngineRemoval041.jpg Tomorrow, i'll start tearing down the engine and see what's up. | ||
| Rdkingryder |
Weird I can't seem to post more than 2 pictures. | ||

When you post multiple images. keep hitting "preview/post message" until they all load. Whatever you see at "preview" is what posts. Zack | ||
| Rdkingryder |
Thanks Zac, will try that. I've disassembled the engine and found the rear rod with play at the big end. Not really surprised as the engine noise was a bit quieter than Hughlysses. I am glad I found the cause of the problem.     | ||

RDkingryder, How many miles do you have on your Uly? (I may have missed that somewhere along the way.) | ||
| Etennuly |
Wholly crap! That one piston looks like it had been in a house fire. I hate to ask what kind of oil you had in there.  | ||
| Teeps |
If this were mine, and I had the $$$. I would get a set of these: http://www.nrhsperformance.com/partscylinders.shtm l for the reassembly. | ||
| Ourdee |
I wonder if that is from splooge ingestion? | ||
| Kenm123t |
Thats carbonized oil Looks like i will be adding head temp sensor to run the fan on temp WOW ! I have one on the M2 looks the rest will too. The piston on the front cylinder looks worn on the skirt. Is that normal? PAMMY ! what do you think? | ||
| Etennuly |
Was that a blown head gasket on the rear cylinder? | ||
| Rdkingryder |
Bike has 30K on it, first change at 1K, then 3K and after 5K used nothing but Harley Synthetic, changed every 5K with new Buell filter. The spot on the rear head was from leaky valve cover gaskets fixed under warranty. I'll try to get a better picture of the pistons, garage is kind of cramped right now. | ||
| Brucespoint |
What is the Build date? This has to be a bad batch, tooling slip up, Bad Monday... What is the pattern, all same. Is My 07 going to grenade when it hit's 30k? If So, I want a Word with the motor company, Not Right. b. | ||
| Rdkingryder |
Bruce, mine is a late '07, June iirc | ||
| Rdkingryder |
Ok, took some not so well lit photos. Rear piston...  Front, see now this one looks bad...  | ||
| Paul56 |
How do the bores look? I see light vertical scratches through the coating on the skirt, but still see original tooling marks under the coating. Rings look free and clean. | ||
| Skifastbadly |
For those of you with 07s, keep VERY good maintenance records. When I tried to get HD's attention, as soon as I told them I changed my own oil at 20 and 25K, they were done with me. | ||
| Hughlysses |
I'm sorry to say all that looks VERY familiar. | ||
| Skifastbadly |
Something just occurred to me. It's probably nothing but sometimes the devil's in the details. A couple of thousand miles before my failure, I changed my own oil...and I overfilled it, which is easy to do on these bikes. As a result, I got a lot of oil blown into the intake. Hugh, Rdking....you didn't happen to overfill before the failure did you? | ||
| Etennuly |
Any one know the piston to head clearance? Lots of carbon piled up there. If it builds up enough that the piston touches the head through it that load goes to the rod bearing. A problem for GM in '97 on Vortech heads with flat top pistons. Good reason to go to a spooge can. | ||

Hugh, Rdking....you didn't happen to overfill before the failure did you? Not AFAIK. Any one know the piston to head clearance? Lots of carbon piled up there. If it builds up enough that the piston touches the head through it that load goes to the rod bearing. A problem for GM in '97 on Vortech heads with flat top pistons. Vern may have hit on something. My engine had a lot of carbon too. It's hard to say though whether the carbon was the cause or effect of the crank disaster. | ||
| Dfishman |
That makes me feel better about my '06 'cause I know I've kept the carbon blown out of it.I do know that when adjusting valves on my Honda XR650R I had the plug removed & looked in the cylinder & saw hardly any carbon buildup on the piston.I'm not sure if it is from keeping the rpm's up or the use of Seafoam in my fuel that keeps the combustion chamber carbon free.Who knows.I'll just keep maintaining & running the piss out of my bikes(without abusing them) & worry about fixing them AFTER they break. | ||
| Brucespoint |
Seafoam for Me! Plenty of WOT too! =8^D If Carbon is the problem, pull that back head off at 20,000, dodge the bullet? be sweet, fingers crossed for that. Meantime Batch Analyses. build dates on All premature Motors? b. | ||
| Rdkingryder |
Hmm, carbon build up. I did seem to notice more than what should have been there. Bike is rarely in stop and go. My commute is 25 miles each way hitting the freeway almost from the git go. My speeds are usually uh, "efficient" to get me to work on time. I'm usually in a "hurry" to get home as well. The carbon would seem to indicate some oil burning or maybe excessive oil getting into the airbox and then being burned in the combustion chamber. Will look at the front piston for the same. I don't recall overfilling it at anytime though. | ||
| Etennuly |
This excess carbon build up is not so much from not running it hard enough, but rather from the fuels we run and recycling oil vapors, and in the case of EGR systems, superheating the intake charge by trying to re-burn too much exhaust gas. It always seems more prevalent in super hot cylinders verses less hot ones. I have been kind of studying this process since my third 1997 Vortech engine failure that I proved to be due to carbon build up in the combustion chamber. On my bike the intake runner has a build up of near a quarter of an inch thick of carbon in the bottom of it. A sign of a very hot zone. So far my theory concludes that if we take the fuel/air mix, add a little oil vapor, heat it in an oven it will turn into hard tar like carbon residue not unlike what is stuck in the combustion chamber and on superheated surfaces of the intake plenum. I have run across the same carbon build up in my EGR'd diesel where the heat from the turbo gets the aluminum intake runners so hot the carbon buildup nearly closed off the intake ports to the rear cylinders. |
