    It looks like for the 250X the part number is Part # 1201540021, the same as the 250R.
    Mfg Part# TFK003D198-CR-BLUE

    Smokin' deal, probably a regulator. Too bad I'm in the wrong country...

    No. The Iridium tip can break if leveraged on.
    Mfg say no gapping needed.

    Sweet, bet that feels great.
    Got a link which one you bought?

    Don't forget Zinzer said to check that.
    I don't ever remember reading about a bad one :scratch before so that was a good call.

    Awesome! Love it when things work out and even better when cheap! :thumb Noticed your tool tube there; looks like one of those tractor manual tubes and an exhaust clamp? How's that holding up? A tool tube is next on my list so always looking for good examples!

    Which clamp is used on that tool tube? I want to mount one on mine as well....I have the tube, but I could never figure out where to get the clamp from.

    It's actually not a clamp at all. It's a piece of thin sheet aluminum I had laying around that I bent around the tool tube and screwed into a couple existing mounting points (*I also used this weird flat piece of aluminum I had as a spacer. I then put a couple rivets into the tube to keep it from spinning around in the metal. It's still pretty flexible so in a crash it's going to bend, not break.

    I couldn't remember who posted it originally, but I have no qualms saying I stole the idea! :)

    Biggest difference though: I mounted it such that I could keep the original tool box onboard. YMMV.

    Thanks. I'm going to replace that on my 08 just in case. The new Kemso pump is working great.

    So I have wonder, what happens to those to go bad? I can understand those defective pumps are built too tight and seize when it's too hot, but what happens here?

    Maybe sitting in ethanol fuel eventually funks up the inside of it? Can you cut it open?

    You used Seafoam, but I've been using Lucas for storage and everyday tank running in everything I own. I've never had ethanol issues in the last 6 years I've been using it. I just squirt a goosh of it in each tank before or after the fact.

    Or do these fpr just wear out over time?

    My bad! I missed that response altogether. Will be adding it to my tool tube research notes though, thanks! :thumb

    I do all of the same. Kemso pump went in "as a precaution", and I too use Lucas treatment to prevent Ethanol issues.

    HAHAHA! Hell YES AwesomeSauce! FTW!

    My best friend ordered the plate WEAKSOZ for his S1kR - I ordered AWSMSOZ the same day. Here they are, Twin bikes, in all their glory outside Manic 5. (*Pssst! Please don't tell the S1kR it's not a dirt bike!)

    The pipe is an FMF without the quiet core installed. It helps that I took the vid in the garage and it had a great resonance. :)

    Loving the Britannia Composites Lynx Faring and dashboard. Great lights, GPS mount, 12v and usb outlets, wind protection. Worth every penny, especially at night! 28DBBE26-B5CE-4CB0-88DC-2F7AF0D1CA80.jpeg

    Purchased from Rick Mayer Cycle. I don’t think he’s still in business, but not sure.

    Somewhere early in this thread, maybe about 2010 or so, there was a discussion about pump failures. Someone had a link to a recall in certain Asian countries where Yamaha stated that the production clearances of the pump's rotors were too tight and could eventually bind and make the pump stall. No reference to ethanol as a contributor was made. Maybe in Asia they don't have "Big Corn" lobbies who buy their lawmakers with campaign contributions?

    I know from first hand experience that ethanol can make non-resistant plastics swell. I had an old Poulan chain saw built in the 1990's that had the gasoline fill plug swell until it was no longer usable. I also have 2 MSR fuel cans. I used one with E-10 fuel, and the plastic plug started binding from expansion. The other only got No-E fuel and works fine.
