Bike stalling while riding
06/26/09 at 19:05:38
 
Hi everyone. I am the proud new owner of a 2002 LS650. That's my first bike and I don't know anything about mechanics but it seems I'm gonna have to learn if I want to keep this baby purring...

Yesterday when I drove the bike home from the seller's place, the bike stalled twice on me while I was in 2nd or 3rd gear, slowing down while I was approaching a red light. It started it again twice without a problem.

Again today, I was driving around 30 and I think I was in 4th downshifting to 3rd and it completely stalled on me. It was kinda dangerous...

Is it possible it stalled because I didn't adjust my speed with the gear I was in??? Or could it be something more serious?

A friend of mine suggested I adjust the idle speed. What do you guys think?

Thank you in advance for your help.

  I think the idle speed is to low.

try running it on "PRI" instead of "ON" just
to see if that makes a difference, if so, then
you have a vacuum leak on ur carb. EZ fix,
just type "vacuum" in search box.

Thank you. I haven't tried running on prime yet but I shall shortly. Is it safe to ride on prime for say, 20 miles? If it works fine while running a prime, I understand the problem could be a vacuum leak.

I searched the forum for this issue and found many posts but I'm not sure what I would have to do to fix this. Please note I don't know much at all about mechanics, and I am French, so all these mechanical terms sounds like Japanese to me...

So, would I just need to replace the vacuum tube? If so, that seems pretty simple.

Sorry for being such a noob...

Yes, just replace your vacuum line first, but when you take the old one off, check to see if there is any fuel in it, if there is, then your petcock is bad, if not, then it is more than likely just the line is bad.

I was thinking and maybe your carb is just
dirty on the inside (what year is the bike?).

I have been running it on PRI for 4 years Wink
no problems at all. You could use PRI all day
and ON at nights to close the fuel flow.

Yes, if damaged, you must replace the hose or
look for damage and use silicone to fix, cut the
ends and re-install the leak is usually at the ends.

* see petcock vacuum hose

And IF you tell us more about your bike
we might be able to help you further.


Good luck

Thank you.

The bike is from 2002 with about 30,000 miles on it. I just bought it 2 days ago and I believe everything is stock.

To be clear, the vacuum line is the tube that goes from Fuel switch to petcock to the carb, right?

Thanks again for your help

The vacuum line usually has a chrome spring wrapped around and routes around to the left side (as if you were sitting on the bike) of the carb.

Well first of all CONGRATULATIONS!!!  (...wise choice)

Second, 30k miles is almost 50,000km, not a problem,
but this changes things.


- your carburator could be dirty inside
soon you must remove and open it with a friend that knows
motorcycles and clean it well and see if all jets are free


- Your spark plug could be old
it costs $3dlls and it's easy to change BUT you must
remove the gas tank first, get a friend to help you
the first time; but you MUST learn to remove gas tank.
You need a: NKG DP8EA-9 aka: ND X24EP-U9


- The first thing I do when I buy a used motorcycle is
a FULL service and check-up: Fresh oil, fresh filters, fresh spark plug, carb wash,
adjust valves, check all electric and breaks, etc.  It's best to do this.  


- Ask previous owner about the TIMING CHAIN
at almost 50k km the timing chain must be replaced soon,
BUT i think somebody allready did this for you  Wink


Battery old?
Many Savages run bad because of an old battery.


- Spark plug cap
If the spark plug cap that comes from the coil is the original,
I would replace it too ($5dlls), because heat and time damages it.



Good luck again and we will help you with everything, no worries!

Wow, thank you for the detailed explanation. It does sound like a lot of work but I understand it's important to keep the bike in shape.

Unfortunately, I don't have friends who ride bikes so I'm kind of on my own... Stimpy, I see you live between Germany and San Diego. If you're in SD and feel like helping a noob, let me know  Grin I live in San Diego too.

I will do the basics (oil + filters) myself as this doesn't look complicated. For the rest, I might have to take it to a shop. I really don't see myself fooling around the carb...

Thanks again for your help, guys!

DON'T take it to a shop. Just go to costco and buy a tool kit and latex gloves.
You can do it!  Wink   (since there is nothing really wrong with it anyway)
And SERIOUSLY, learn to remove the tank and put it back together,
learn this and you're 1/2 done with most everything, trust me.

Yes, try the seafoam, that might clean your carb up
w/o having to open it for now. Great idea bill!

* sadly I left san diego a year ago and am now house-sitting in Mexico City,
but I'll help you w/whatever I can from here (MSN: stimpford@hotmail)

Keep us informed.

I had no problem yesterday but the bike stalled on me AGAIN today while driving. That was kind of a dangerous situation too...

I was in 3rd and all the sudden I could feel the bike didn't respond to the throttle. It felt like that bike was needing gas but it didn't get any.

I started it again and it ran for half mile and stalled again. This time, I put the fuel valve on PRI and it finally was able to take me home without stalling.

I looked at the vacuum hose and it looks very good. I mean, it's clean and there doesn't seem to be any damage or leak.

Tomorrow, I'm going to go to the shop and buy:
- a new air filter,
- oil filter,
- oil,
- vacuum hose (any specific size needed?)
- a can of Seafoam

You're right, I should learn to fix remove the tank.

Is the Clymer book a good investment?

Thank you guys.

I told you it was your gas valve!
forget about your vacuum tube, just leave it on "PRI", problem solved  Cheesy

----------------------------------------------------------------------------

dude, air filter is $50   Angry   ....just thought you should know

----------------------------------------------------------------------------
Most everything in the manual you can find right here in this forum,
plus a lot more. But yes, the CLYMER savage manual is pretty
helpful and it's nice to have it on paper with you while you fix
your bike, but it's kind of pricey ($25)

OR you can download it in .pdf here you wish (and print it) Wink
