    I'm still running the original pump on my 2008. No issues yet, but I have a replacement ready when it fails. I run 87 in it with no issues and only put ethanol free gas in there when I know it will sit for a while. I have other bikes that only get ethanol-free, but the WRR is tough enough to handle it.

    Well now you've done it!
    I definitely notice more green oxidation in carburetors that have sat with ethanol gas in them than I used to. I try and let the bike winter over with a tank of Seafoamed Chevron 94 octane.

    Seafoam is the best invention since the wheel - or the carburetor - or the fuel injector.

    It was just a pump supplier issue and that supplier building the pump slightly different so it does not bind when hot.

    I just replaced my 08 proactively.

    Seafoam was in the bike that had a fuel pressure regulator go bad from sitting.
    Yes Seafoam is loved but never really claimed as an ethanol solution unlike

    I use this for winter storage and Walmart has it on the shelf. Avoid the cheaper Stabil red, it's for storage but not storage and ethanol.

    Or

    Which is available at Napa.

    I add Seafoam to Chevron 94 octane which is ethanol free, so I have no expectations of it treating ethanol.

    Ah got ya, you didn't mention that.
    That must be an local area thing you just expect to find. Not so around here.

    And no Seafoam does not claim to solve ethanol problems. If find it does not do much vs other products.

    If you guys are looking to really clean up your injectors and carbon deposits, PEA - polyether amine, is the best ingredient.

    If a cleaner does not have that then it's just using less effective & cheaper distillates.

    Redline SI-1 has the most (more than 44k, Techron & others) and is thus tops. It can be found at O'Reillys.

    Of course these are not ethanol treatments like marine Stabil or Startron or everyday additive like Lucas fuel treatment.

    An excellent fuel routine would be Redline clean in the late fall, oil change right after, fresh tank of gas w/marine Stabil for winter storage, use Lucas every tank the next season till the next Redline clean & repeat.

    Winter appears to be here in Wisconsin and am looking to store the bike for winter. Looking to store this year without heat or power for a tender. Is it okay to remove the battery for winter to store at home? I recall reading of some head units dying from dead batteries, or is that unrelated? Never had a problem pulling batteries for winter in the past, but want to confirm.

    For what its worth, I'm in Minnesota and have pulled the battery on my '13 every winter since new. No issues with dash or anything electrical. Same with the '03 SV650.

    I'm trying to re-install the EXUP on a new to me WR250R. Can anyone confirm the orientation of the cables? Is it really as simple as cable 1-1 and cable 2-2? The only reason I even ask is because this orientation forces the cables up against the hot exhaust pipe (in my case).

    Also, Is there a diagnostic test like the fan test to confirm the correct functioning of the unit?
