Title: noob engine rebuild/ DO NOT USE HIGH OCTANE FUEL!
Post by: drkslayer on June 14, 2007, 01:16:56 PM
so... I posted on here awhile ago... I was pissy and just let ole girl sit for awhile, then got a hair up my *** and decided to pull the motor apart and find out wtf happened...

well... I heard this nasty clanking after coming back from a ride... I thought for sure it was in the head...

but strapping it to the truck, and letting my buddy take a listen definatly brought the sound down, so I knew it was something to do with the crank...

now that I've got it apart, the first piston I took off, I noticed the problem...

the left c-rod came loose... so loose I can rock it back and forth... how lame...

the only thing I can think of was the 101 octane I put in it like 2 months ago... 3 tanks later and I have issues...

I wouldn't reccomend it... even tho it made her scream... it unfortunatly did damage...

any reccomendations now that I have it apart?

should I replace everything? or just the bearing/ have the crank turned... I just moved and money is tight, and would like to keep this as cheap as possible... anyone in the area that would mind making a new riding buddy in exchange for some guidence on the rebuild, and free beer?

here's  where I stand...

Keep going, you're still going to need to inspect the crank journal under that c-rod.

yeah so tell me how too high an octane rating will damage your engine.  I'm sure you mentioned it, but I just can't find it.

I just  cant see 101 octane hurtin the GS :dunno_white:  damn engine is just more durable than that.......Now stabilized jet fuel on the other hand :o

yeah, high octain didn't do that, it was just bad luck.

Maybe if you used high octane fuel instead of oil....

Pretty much the only major cause of failure in the GS motor is lack of oil.

Might as well split the cases and check all the bearings.

I dunno... with only 11k... and I didn't have problems till I used the high octane stuff... and turns out both the c-rods have play... one worse than the other...

I mean... bad luck or not... usually there is a reason... oil, careless rebuild, whatever... and I can't really find one, cept for that...

Considering jet fuel is just diesel or kerosene, it could do some damage, and wouldn't be any fun to run.

with the appropriate compression and timing  JP-x could be used in a diluted form and would produce insane numbers but reliability would be severely compromised.   in a stock setup it wouldn't ignite.....be like water in your gas :icon_confused:  you'd probably need to figure out something other than the stock spark plugs too..........hmmmmmmm ;)  I might have an idea for my totalled GS :icon_twisted:

depends on what you  jet fuel you get .. you can get TTL100 and it is fine. you can run that in your car ... or in my case i use to run it in my dirtbike ........ it all depends on what you get ..

dude i run 130 at the track and 10k miles later i don't have any problems. that provably from you winding it out like a Buddha Loves You and thinking that the 101 oct fuel is going to keep it together.

don't blame it for your recklessness

In the US
100LL is standard aviation fuel for piston engine aircraft
Jet A is extremly high grade kerosene
JP-8 is a high grade diesel thats' had the sulfer removed

I was an aviation line service technician and pilot until I injured
myself.I pulled a muscle in my stomach and give myself a
hernia.Now I can't return to work because I lost My FAA
Airmens Medical Certificate.The doc says that my strength
has been compromised and I couldn't fight the controls of
an out of control aircraft long enough to recover the flight.
Sucks!I really miss the money.Sorry.Didn't mean to go into my
life story.

Fly on my friend,fly on.Find and fly with a military pilot from nam era.I did.
Learned to recover from almost anything.I also learned to fly inverted in a
Cessna 152 without ripping the wings off.The tower didn't like that when
we done it over center field.They claim we were encouraging other pilots
to fly dangerously.  :laugh:

Yeah, Nam era pilots are bad-ass :icon_twisted:  One taught my uncle through about 90 hours.  He gets bitched at all the time for making low-passes of the runway before landing :icon_twisted:  ( I'm talking like 2-3 feet at 150mph+ )   I get bitched at because I like to take my time recovering from stalls :icon_twisted:   So much more fun coming level at a few hundred feet rather than 1500-2000.  Gives the instructor a good wakeup :laugh: :laugh:

Wow, lots of pilots/student pilots here, cool! I have my commercial single engine land and sea and I'm working on my CFI right now. I fly skydivers most weekends to help build the hours.

The only thing about jumpers is that they don't really give a sh*t about the airplane (since they're planing on jumping out anyways) So you need to know when to say no and walk away from a messed up plane.

Once when I was decending at about 165 MPH the door rattled open, ripped off, and smacked into the tail, beding it about 30 degrees  :o
That was my scariest moment.

I've got over 30, but I'm grounded for the next 5 months for injuries I sustained landing out in a glider.  It's torture... but it could've been much worse...

I'd would've jumped out then.Emergency landings can be fun,if you know you'll survive.  :laugh: I'm an adrenaline junky.  :cookoo:

like taking it to 9 grand every once in a while is reckless... wait... no you are right... yes... actually I would just sit in my driveway and redline it cuzz I liked the high pitched whine...

the name-calling is helping alot too... keep it up :flipoff:

You gotta work to f%$k the GS engine up.  I've taken it to 12k several times and consistantly run it at 9k for extended runs.     Never flinched :thumb: :thumb:  The only way I know of to kill a GS is run it dry of oil :o

diito....ive taught people to ride on my bike....they have wound it up to as high as she wiil go and still held together.   Just face it dude you forgot to put oil in it.. I know the gs like to drink it. and if you had a leak that would make it worse. dont blame it onthe octane.

ohhh. and since we are talking about flight stories.. .one time i clipped a turkey on a short runway take off.  :o  yea that was great.... :cry:

Title: octane noobs
Post by: Gookie on June 16, 2007, 05:02:16 AM
Biggest noob comment ever, tuner cars in general, and people who think they're going to make their Hyundai Elantra a rocket ship...

"Octane" is a rating, combining several factors, that determines a fuels resistance to pre-ignition. So, unless your vehicle REQUIRES high-octane fuel, or you're using it as a band-aid for other problems in older vehicles, the only way it's going to make your vehicle faster is by weight reduction in your wallet...

If it existed, you could put 3,000,000,000 octane in the GS500, and the only thing that would have bought you is the assurance the engine will never, ever, knock...

Octane does not mean "more energy". (well, it does to a certain point, but, the differences are so minute, you wouldn't be able to notice them...)

Anyway, that is all...

so... I have the 2 1/2 quarts of black oil I drained out of the bike when it started making the noise... this is 800 miles after I had it serviced, tires, brakes, timing chain adjust, tuneup, and supposave oil change...

everyone (the assfucks included hehehe) claim it was oil, and not the fuel... can I go after them, or just suck it up? I just moved to buff, ny... and I had the bike serviced in seattle before I moved...

is there a "rebuild kit" that I can buy, or should I inspect each piece individually and go piece by piece?
Title: Re: noob engine rebuild/ DO NOT USE HIGH OCTANE FUEL!
Post by: nastynate6695 on June 18, 2007, 07:18:32 AM
black oil.....nice... :thumb:  are you sure they just didnt polish off the oil filter and give the bike back to you without changing the oil.  I know shops that do that stuff.   Thats why i always change my own.

Get a Haynes or Claymers manual it will explain how to do a rebuild ( at leat I think it will does in my other Haynes's )

Buy the parts you need don't think they really make a rebuild kit but I know they sell all the gaskets in a set.  Just follow the book and rebuild your engine.

And guys does it really matter why his engine is f%&ked?  He's looking for advice on how to fix it.

No rebuild kits except for aftermarket gasket kits. Partsnmore.com and ebay are the best source for them.

Piece by piece is the only way to go.
