If you need a ride, i will loan you a bike as I have several.
Wow, that's a helluva nice thing to do. And brave too! Good for you man. :clapping: You should be teaching "how to make friends and influence people" classes. Jeez!

And to think I've always heard Californians are all self-absorbed, materialistic, ego-driven and possessive! :huh:
Uh, you don't know the meaning of the word 'loan', do you? ;)

- Guido "The Capper" Tortelli
TWN, I know Steve well. He cared enough about me to visit me as one of my first visitors after my descending aorta replace last 28 December. He is a very experience rider and a great guy. To define "Loan", its come get it ride it with no strings attached. My bond is my word these days. I'm not pissed at you just wanted to clear up what I said is what I meant, no strings attached.

Later

sincerely

Well congrats on 100K. Let us know how this pans out as some of us want to see that milestone on ours.

 
Sure, something else MIGHT break--its 100K. So what--you fix it as it needs it. I'd pull the head, check valves/guides/rings, replace what's worn. Or, go ahead and complete re-build with new pistons, rings, valves, guides, bearings--like new--for a helluva lot less than a new engine. Dealer says "new engine" because 1 cyl is low--typical stealer BS.

 
Pull the head, rebuild as necessary, or as others have pointed out grab a wreck of ebay.

There was an 06 down the road from me for less than $1500 that looked better than the one posted earlier.

I'm sure all the parts you need would be good ;)

 
I had Mickey at Mickey Cohen Motorsports in Placentia, Ca. do a leak down test and the results aren't good.

cylinder no. 1- 115lbs with 29% leak down.

cylinder no. 2- 113lbs with 50% leak down

cylinder no. 3- 0lbs with 100% leak down

cylinder no. 4- 50lbs with 85% leak down

Instead of trying to rebuild this engine, I bought a used one at Rancho Motorcycle Dismantler for $1000.00

They said it only has 2000 miles on it. I think they have had it for a while because about 18 mo. ago I had a ignition switch go bad and I bought it there.

Its funny, everytime I need a part for one of my bikes, they always had it.

I don't know what made the engine go bad so quickly. In july I had the Muzzy pipe and Power Commander installed and the bike made good power. (Check out the dyno chart at the muzzy pipe sucks thread)

I sure hope I don't get a ticker!

Thanks to you all for your help.

 
I guess it would be cost prohibitive, but it sure would be nice to break down that engine and figure out what went wrong.

What a bummer. Not good.

I will be hitting 100k early in the springtime. So far, with 91k, mine still runs like a ***** ape, though Warchild still insists it's a ticker.

Hope yours is an anomaly.

So, now for all the particulars..............What kind of oil, oil change interval, gasoline?

GROUP BUY for a teardown! Or... better yet.. have one of the board gear hedz do it for a coupla beers! I too would really like to know..

Mostly mobile 1, always synthetic oil.

Changed every 5-6k miles.

I used just regular gas.

Yes, if you don't want to do it... At the very least save that baby for WFO or something... I'm sure there are enough of us to chip in to ship it there and we can tear into it ;)

I would be very interested in knowing if it was top end that gave up or something elsewhere.

And what Skooter asked. Oil, change interval, gas, etc, etc. Even though it probably doesn't matter all that much unless you used something really off the wall.

 
Not sure if memory serves me right, but wasn't it 03SilverBullet who was seen doing *gasp* BURNOUTS on an old tire at the dealer? Did he really disable the rev limiter before multiple track days? Did the Muzzy exhaust and PCIII hole the pistons? Is it true he regulary installed knobbies, removed the air cleaner, and went beach riding in the dunes? Or do all FJR's self destruct at 100k? Where is ODOT's tree when you need it? Stay tuned boyz and gurlz.. The truth will eventually be known! :D

Hey 03'.. sorry to hear you are having spend $$$ on your ride.. sure doesn't seem right that the motor would implode at 100k. Keep us posted??

LOL, all of that would have been OK if he'd have used:

Not to question your wrench but the leak down numbers doesn't tell you where the problem is . If it is a bad intake valve you will hear the leakage through the throttle body or air intake and if it is a bad exhaust it will talk to you out the pipe and finaly if it is rings you will hear it through the crankcase. The numbers are fine to look at but if the leakage is just in the valves then you don't need to pull the engine to do the head. Yuo could still buy the spare motor and use that head and save the rest for later.

I hear it through the intake.

According to Mickey the other cylinders are leaking through the pistons.

Thats why I think I will need more than a valve job.

 
Until this motor is torn open and diagnosed by a competent wrench, it could be anything? Something just doesn't sound right with this sudden decline toward failure, since it sounds like it was running tip top until just recently.

I understand the facts of the diagnosis, but I would also question your dealers move to offer you a new engine without first proposing a diagnosis to determine exactly whats up inside there. I also understand that some dealers do not like tearing into engines and prefer to stick to routine $ only tune-ups, so maybe they are one of these?

If you are close by to turbodave, I would book your FJR into YOC and pay for a few hours of a very experienced crew of wrenches to find out the real scoop of your engine, it might be well worth the $'s. If you decide to fore-go this route and just install a replacement, you can trust YOC to do a top rate job.

 
Hmm....hate to say this this way but something seems odd about running fine all those miles and then putting on a pipe and PCIII and hitting the dyno and a subsequent failure.

Sounds like there might be a lean spot in the PCIII calibration that may have caused burnt valves...???...or even a holed piston. I would suspect a burnt valve rather than a piston/ring problem but never say never.

That is one of the problems with doing tuning work on a high specific output engine like the FJR has. They are typically not very forgiving of beging run hard with a fuel injection calibration that is slightly off. And if it was "tuned" on a dyno for max output then it is even more scary because what makes nice dyno numbers is typically too lean for day to day operation and hammering on it repeatedly....or running for periods of continous WOT. Easy to burn a valve due to high exhaust temps and/or get into detonation from too lean a mixture and/or induce preignition via plugs that are too hot for the (now) too lean A/F ratio and/or get into detonation induced preignition from leaness under heavy load.

I suspect that there is a correlation between the pipe/PCIII/dyno tuning and the loss of compession and high leak down rates.

Excellent points. Sorry his engine went boom, but you're making good and logical points.

And frankly... I wonder, why the pipe? Are there actually people that think this bike isn't ballsy enough? Most people will scream it's a sport-TOURING bike.
