Title: 87 Savage--won't shut off
Post by drums1 on 07/06/07 at 08:33:15

OK--I've aquired an 87 Savage LS650. It seems to run ok except for some funny noise...but when key is shut off and removed the dam thing keeps running. I'm told it needs a new starter. Any idea's? :-/

so does the run/stop button kill it?

...and can you better define/describe "funny noise"?

Funny noise like the starter stays engaged while running. And no, even the start/kill switch does nothing--key off and out--keeps on running. I saw another post further down here that described almost the same thing as I am experiencing. Bike sat for 1 1/2 years and has almost identical symptoms. I'm going to try some of the remedies that were suggested in that post. Like pregnant dog-slapping the relay and the solenoid. And looking for a short under the seat. Bike was kept in Abundantmouse county. Any other suggestions are also welcome.
Thanks.

Hi
Could be a build up of carbon in the engine. The heat retained in this can continue to ignite the petrol even when there is no spark.
May be worth a quick look inside the exhaust outlet to see what it looks like. Also is plug looking sooty, this would indicate a rich mixture.
I have an 86 model which is runnning very rich possibly die to a worn needle jet. See my post for the details.
If the mixture looks OK a good blast at high revs with a good qaulity, high octane petrol may burn off the coke.

Nah, this is not a "run on" type problem. This is a "keeps on running" as if key was on type problem. Like a short, or a stuck solenoid.

How do you stop it?
If it's a stuck starter solenoid, the only way to stop it is to pull a battery connection off. (From what I can see in the schematic)

So how long has this Savage been running? I'm sure a tank of gas wouldn't last anymore than a few hours?! LOL! ;)

I guess you could always yank the spark plug. But does the starter keep trying to crank the engine after it's yanked?

Part number 19 (http://www.ronayers.com/fiche/300_0039/carburetor/carburetor.jpg)'s o-ring is worn smooth with the brass into which it's set.

If you don't replace that o-ring, in 2-4 months your carb will start overflowing. You will, shortly thereafter, drain 9 quarts of oil out of your engine. Then you'll get really, really p1ssed the f8ck off. And scratch your head and swear. A lot.

Just replace that o-ring. The needle float is the same as the one for a Harley's bs40, or at least close enough that it works.

anyone have a wiring diagram for this bike? (haven't had a chance to pick up a manual yet)

Drums,

I know this is a really old post, but I was hoping that you were still on the forum. Did you ever figure out what caused this? I had the exact same thing happen to me last night on my ‘01 Savage. There was a rattling sound coming from the clutch case, so I assumed that my cam chain tensioner had finally overextended and died. ( I have the mod on order from Verslagen and am awaiting arrival). I went to turn off the bike with the kill switch, and the bike continued to run, but it went from a smooth idle to a rough chugging sound. Even removing the ignition key did not stop it from running. When I replaced the key and turned the kill switch back to on, it resumed regular idle. (Still with a rattling sound from the clutch case) Repeated this several times to no avail. Luckily, I installed the Raptor Petcock last month, so I turned it to off, and the engine finally died in about 4 minutes. Did you find out what caused your problem? It sounds exactly the same.

This bike sat for about 4 years before I bought it last month. I got it running and haven’t had a problem until now. I tried searching the forum several times, but I can only search back one year, or I get a timeout error from the site. The only reason I found your post was from a google search. Any help is appreciated. I am thinking it might be a short somewhere, but would a failed cam chain tensioner cause this? Thanks!

Are either of you running larger jets than stock ? what are your carb/air filter setups? what are your elevations?

Title: Re: 87 Savage--won't shut off

All carbs/jets/air box are all stock. I spent a few hours troubleshooting yesterday and determined it’s most likely a stuck starter solenoid. Which is weird because I replaced the solenoid last month. I had disconnected the battery after the bike finally died. After I charged the battery off the bike and tried to reinstall it, the starter immediately cranked as soon as I connected the battery. This is despite the keys not even being in the ignition and the kill switch in off. I thought the engine finally died due to fuel exhaustion, but I think in fact it was due to the battery finally drained too much to continue to run the starter. Waiting on starter solenoid number 3, so I can install it. Is this a common issue?

Also could be a bad decomp controller, little black box over the carb.
check to see if you have 12v going to the relay on the small wires.
if it's on all the time, then it's not the relay, it's the controller.

I agree with verslagen1. If the starter continues to crank and the engine still runs with ignition in "off" position then the compression release relay is the most likely culprit. If ir was only a stuck solenoid the engine would not run with ignition off. It would only continue cranking without starting the engine.
