WTF, CURSE OF THE DYNO!!!!!!! *IT"S TRUE!!!*

[starshooter10]

the curse of the dyno is TRUE!!!

TRUE I SAY!!!

i drove ~65miles to a free BBQ and DYNO day at a semi local bike dyno shop...

RAN FINE

i did wheelies up an ddown the ally behind the shop FINE

ran 2 pulls on the dyno FINE


going home i made it ONE BLOCK

it was making a funny click click (to the RPM) when i pulled to the end of the alley

made it half a block it got LOUD

NO POWER!

couldnt rev over 8G's (normally it winds to 11k NP)

click turns to CLACK!

to CLUNK!!

RIGHT befor ethe intersection that would make the 1 block mode....

BANG and engine dies (rear tire locks)

grab the clucth flip a U

coast back to the shop at 15 MPH (downward slope)

i though i maybe broke a valve sping of dropped a valve...

popped off the valve covers

looks good (STINKS)

pulled plugs and tried to spin the wheel in gear NO GOOD

i think i spun my mains....

CRAP!

oh well...

i'll open it up later and figure out exactly what went wrong..


any idea's buddha?

and PS...

my oil smells horrid...

[GeeP]

Don't abuse your bike and it won't leave you stranded.  Wheelies / dyno runs are a proven way to blow things up.   

Sounds like a thrown rod.

[ke7syv]

There's a couple bikes being parted out on Ebay. Not sure what year you have but it might be worth checking into.

[starshooter10]

bah

im not trying to prove anything..

im mean really, what would i prove by going to a free dyno day?

the lowest powered bike there (outside of the other GS and mines... ) was a nionja 650 that put out almost double...

and the wheelies...

well those are fun

dyno = curiousity
wheelies = fun (for me anyway)

i'll check by the local cycle salvage place and see what they can do for me... but chances are i'll rip this engine apart and say SCREW IT the cyl and rods are screwed.. or forget to put it back together...

im thinking im gonan take the rims tank and other useable parts off and give them to my roomates (i just gave him my other GS for X-mas)

and i'll look into another bike...

i dont think it'll be anther GS though

as much as i like it when i rode 2up (before my GF dumped me last month   ) it was too low in power...

that and i kinda like the idea of a sport touring like a ZZR or interceptor

i'll proablly stick around here a bit though as my roomate still has one.

[makenzie71]

So what'd you pull on the dyno?

[ohgood]

So what'd you pull on the dyno?

i'm picturing you dead-panning that one... i had a really good laugh.

as far as power for 2ups, me n the wife ride just fine at 80 mph. no issues with acceleration here. braking is annoying, but not unsafe.

guesstimate: maybe your bike was a little low on compression, and was compensated for with rpm's. whoolies are fun, agreed. dynos.... i've heard very bad things.

so, you got a chart, right ?

[The Buddha]

Clicking to clacking to clunking to locked up in ~1-2 miles is exactly how my friends GS died.
We swapped the motor on 4th of july 07. He crashed it into the side of an SUV labor day 08.
I am guessing these bikes dont like holidays. That's why I never ride mine on holidays.
Anyway, you prolly lost a rod bearing. Worth an open and look ... and make sure you dont have goats first. In fact if you had a case of goats, bad case of goats, very bad it can do exactly this now that I saw that other guy's (from italy - forget his handle and lazy to look up). Very acute goats, maybe starwalt+severe goat+italian guy's.
Cool.
Buddha.

[sledge]

The guy from Italy...... genTle, he didnt have Goats. He lost a magnet because he didnt use an extraction tool and instead decided to smack the rotor with a length of 2x2 and a lump-hammer.

[starshooter10]

i did get a dyno sheet *cool* also got a dyunosheet from a nearly brand new GS

my bike was about on par only 1HP less hehe


and as for the power... i used to take my girl to san fransisco where some hills are like 20* O_O

need something with more "UMPF" and more "WHOA" (go and stop)


and not sure what a goat is.

mind sharing what your numbers were ?

san fran on a gs500- man, i'd love to ride up Hawk Hill and sit a spell. you're in a fine part of the planet!

Oh I thought the rotor was sheared making the motor make banging noises ? NO. Motor made no noise ?
Cool.

GOATS is what they call a common problem dealing with the starter and internals of the GS engine basically destroying itself...I think.

Oh...... I always thought Goats was the term given to a fault caused by a magnet coming lose from the inside of the rotor.......and unless I missed something there was no evidence of this from the pics he took on the initial stripdown 

[The Buddha]

Goats is when magnet and stator come in contact by any means neccesary. Like in my case, they hit and sheared each other over a year of ignorant use. The rotor however was so tight on the crank that the buddha had to invent tools which promptly failed, and then I had to weld the bolt to the magnet and then use the sliding hammer and get it out.

The only way the sliding hammer was even going to make a scratch on the surface was if the bike was strapped in the back of a truck. BTW the magnet is near impossible to get off once the motor is disassembled unless you clamp the crank in a vice and hit it with a hammer if the rotor is on tight.

In some cases the rotor and stator may not have much damage at all. Mine was butchered though. Anyway, so what exactly was his problem - nothing ? Bad mechanics spewing hypothesis in an effort to drum up a big bill ?

Cool.
Buddha.

[bikejunkie223]

Sounds like with all those wheelies you either cracked a mirror or let the smoke out. You're effed....

[starshooter10]

well everyone seems to be asking for the numbers and a pic to provie it....

here the proof.... (of all 33.61 HP )



it only cost me my engine :rants:

[sledge]

it only cost me my engine :rants:

........ and your tyres!

[starshooter10]

i still think spelling tire tyre is weird lolz

and i think im good on my tires...

i'll probally end up givinig these to my roomate (i gave him my other GS)


that or i'll franken bike my honda engine into the GS

[The Buddha]

33.61 is a bit on the low side, maybe it started its failure when it was in the dyno. My friend who killed his said it was getting weaker as he rode it and obviously he ran it harder in that last 3 miles.
Stock should be closer to 37-39. I did a jetted +piped+filtered bike ~43 or so.
Cool.
Buddha.

[starshooter10]

yeah but im also running SUPER fat.

IIRC i have 40-137's

the top end was okay but the bottom HA!

that and i suspect a coil was on it's way out too (causing stutters in the upper ends and hard starts)
