You put ony enough gas for 30 minutes, after that the engine dies...  

[Blueknyt]

this happens only once reaches certain temp? this happen the same way if sitting for 10 mins?

[werase643]

back to the top..... if yall give up i'll just send the $ to john.....

[pprider]

i dont know if bikes even have one... but here goes

temp gauge stuck open or malfunctioning? causing the bike to over heat? or are sv's air cooled

sorry maybe anoob answer but i tried!

[cernunos]

TPS or IAT...I think those have 'em anyway...at least a lot of bikes made now do. A guy bought a new one at the dealer about a week ago. Told 'em he'd been riding for years. They started wondering what he had been riding when he kept putting it all the way down and then one up for first, killing the bike when he tried to take off. They finally had to show him where first gear was. He wrecked real bad just 4 miles from the dealer. Love the GS500 and the forum too.

Friend said it ran bad and had been sitting for a couple of months on P.O. front porch.

Pure shot in the dark: Some critter had built a nest in a sensitive location. (air filter?, obstructing cooling air?)

[john]

Just a crazy thought...is your tank bag preventing your gas cap from venting?  I suppose it's possible

I AM the guru of SV jetting and I can tell you that 1 jet bigger than stock (140) and 2.5 turns is fine.  Check to see if there is a shim under each needle - maybe 2.  If not at least add 1.  Water is not nice to carbs but you would have seen corrosion.

not sure if anyone has suggested this, as i havent read the whole thread. my brothers cbr 250 used to run like a dog and we had it tuned by a proffesional and it had a "soft" spot from 4,500 to 8,000 . turns out it was something in the ignition. a new cdi fixed it.

[werase643]

We have a WINNER! ! ! ! ! !

think outside the box people.....

the first person got the problem.... but not the cause!

the tank was vapor locking....as the fuel left the tank....30 minutes.....the space was NOT replaced with air....since the tank bag rubber anti-scratch bottom formed a PERFECT seal to the top of the tank.  I pulled over on side of road and when i pulled the tank bag off....it had a vacuum formed impression on the rubber and a sucking noise from the tank....the tank vacuum was higher than the intake vacuum at low speeds.....therefore fuel starvation!!!!  when opening the throttle....the intake vacuum increased above the tank vacuum and it ran.  Hindsight....the problem with the fuel cap drain.... since the tank was in a vacuum condition... the tank contracted....until the drain connection failed.  I repaired the drain connection and  caused the same problem.

John is the winner for reading into the problem.  I caused the problem by taking a tank bag full of tools to fix a problem....that i was causing.

I fixed the problem on the side of the road by taking a bandana and laying it on the tank.....breaking the seal....rode the last 80 miles home shaking my head for....not thinking.  I should now have a reliable bike to ride.....  until i fix another GS up.....the SV is kinda boring...i like shifting and wringing the shaZam! of of a bike....and only going 65-70.... the SV will pull itself out of a 20mph corner in third.... i never shift anymore....

John i'll PM you for your addy and donation....take the woman out to eat...better than MC-D's....

[octane]

...and all this time I thought we were trying to help you fix a problem you hadn't already solved! Silly me.

[john]

I knew there was a reason I always moved my magnetic tank bag up far enough to reveal a bit of the gas cap. :mrgreen:  I always suspected it could cause a problem...

[Blueknyt]

SV is kinda boring...i like shifting and wringing the shaZam! of of a bike

Ill trade you, my GS, extra engines wheels and parts, for your GS, its titled an registered.

[Blueknyt]

Errr Your SV rather.

[werase643]

...... I wanted a SV for....5 yrs... i think i'll frankenbike it for a while.

...... I wanted a SV for....5 yrs... i think i'll frankenbike it for a while.

I had one for a couple years.  It was indeed a fun bike, but I tired of it.  Anne didn't want it, and it shifted like shaZam! right out of the box.  The whole "wait a few thousand miles and it will improve" BS was just that: BS.  If a bike shifts bad when new it will probably shift bad forever.

Perhaps if the tranny was good I would have kept it longer...

[Blueknyt]

Anyone know of a basket case SV laying around??

[octane]

I think werase has one!  :lol:

[The Buddha]

<snippage>

If I let it sit for 1 hr, it will cool down and run good.....till it heats up and starts running bad again

OK cool down.... OK... Lets hear it for misleading diagnosis ....
:lol:  :lol:  :guns:  :lol:  :lol:
Cool.

[werase643]
