    04 R1150GS.

    When it's hot, as in I'm at a long traffic light or draw bridge opening and I go to restart it the starter barely works. It'll cycle very slowly.

    Is that symptomatic of a failing starter motor?

    Thanks.

    It's not an issue when the motor is cold.

    Mine always soudns a little "tired" on a hot start. No idea why. It's just enough to make me think, "Wtf?" then it fires up and all is well.

    Mine fried at work when trying to start, it sounded like it was slow to turn things. I looked down and noticed the wisp of smoke trailing out from under the plastic cover.

    I guessed at that point I'd let the smoke out. :lol3

    The tow truck driver wanted to pull start me with the truck. By the look of him I was certain that movie of that would have hit a million on YouTube. :rofl
    I opted for the platform tow ride home. Slick inclined oil streaked bed. Overloaded top heavy Adventure bike... What could go wrong.:huh
    I didn't drop it, but it was close a couple of times.

    And FWIW, don't buy the OEM starter. That thing is not KLR-priced.:eek1

    If I had known about the Valero I'd have bought it.

    They are relatively straightforward to remove, dismantle, clean and lube and of course a good close look inside, especially the magnets. They always operate well after this task.:*sip*

    On mine the field magnets unglued and locked the armature, this let the smoke out.

    What do you folks use to reattach the magnets?

    I have had very good luck thinning regular silicone seal with toluene into a thick paint, and reattach the magnet with it. But if any chipping you will lose torque, so the updated housing is best.

    Replaced my valeo starter after the magnets loosened and made the starter useless on my '98 GS. Replaced with a starter from these nice folks, a bit pricier than the frog starter, they use nippondenso components.

    BTW, if you have lights, fuel pump and can push start the bike, you're probably shunting a lot of current through an 'iffy' starter which tells you it's probably not a battery issue. My .02. Let us know what you find, yellow, right?

    Also, here's an inspection procedure: http://www.largiader.com/tech/valeo/

    I'd go ahead and drill out the rivets to get a look at those magnets. Replace if needed with the part from EME. The starter on my 1100 locked up last week and fried something in the wire harness. Still trying to find the issue. Not fun at all.

    Might not be the starter. Have you had the bike in your pickup bed? Perhaps it's just some crusted over cole slow that got in there. :dunno :lol3

    As long as the magnets stay put, vagueout's clean and lube is the way to go. I removed mine about a year ago just because, cleaned and lubed the helix and end bushing (did not go inside the case) and reinstalled.

    Never better.
