    Anyone upgrade water pump impeller 11-16 250/300?

    I believe Boyesen still makes one . I am using it in my 11 300 along with Evans because my larger tank prohibits a fan kit due to a lack of space. I have been all over the Rockies and Moab with no issues. Still using the stock radiator cap and some better hoses.

    Tusk Radiator Cap with Temp gauge

    Been working as advertised on my 300 for years.

    2018 500 EXC-F Euro Map

    Has any one who had the Euro tune done went ahead and added a vortex? Worth the $$$ or just a Bliase tune to supplement the Euro re map? I have the Euro, de smog, pipe and reeds removed but have no reference to another bike with a Vortex. Thanks

    2013 500 exc smoking on startup

    Usually, this means valve guides/seals are letting oil into the cylinder after shut down (cooling) causing the white smoke on start up. Once things warm up and tolerances increase, the oil seepage stops. But as was mentioned, get a compression/leak down test performed first.
  5. Greetings,

    I have a 17 500 with a dealer remapped ecu (euro), de smogged, reeds out and a fmf  slip on. I have been reading about the JD vs. Vortex, and was wondering if either one would be an improvement to what I already have? It seems like it helps stock ecu's but mine seems to run very well as is ( no pops or flame outs ever). Should I be looking at a fix that may not be needed?

    Buy Once, Cry Once?

    Put one on my 17 500. Works good, lasts a long time.

    Watch out for the heat generated by those higher out put bulbs. I put one in my 300 and it melted the housing unit and shorted out the bulb. Seems there is not enough cooling air at low speeds. If you are going to do a lot of night riding, spend the coin and get a head light assembly to handle the task.

    Good Fender Bag

    In addition to notching the fender, drill a small hole in each attach point then zip tie to the fender.

    Chest Protector? (Recommendations, etc)

    Tek Vest and forget the rest! Spend a little more for a lot of protection. The extra money spent will pay back huge dividens when it comes time to compare bruised ribs vs. broken ones. Don't ask how I know. Buy the best gear you can afford because the few dollars saved won't be worth the expense.

    6D ATR-1 Helmet

    Go to web bike world. They may have a test on it.

    Acerbis or IMS on ‘16 500?

    I like the IMS because they have metal inserts for attachment and if you use a tank bag, the gas cap is centered on the IMS and offset on the Acerbis which makes mounting a little more difficult.
  13. Greetings, Has any one performed the usual mods; de smog, euro map, exhaust mod or fmf slip on, then installed a vortex? My 17 500 runs as it what I think it should with these mods complete. Since I have no access to another 500 with a vortex to compare it to, I was curious to see if the added coin was worth any performance gain above what is there now. Thanks.

    2017 500excf Gearing? Pics

    I went with a 14/48 so I could use the stock chain. I could see no reason to buy a new chain just for a gearing change since this bike has such a wide power spread that it works good on any mountain pass and single or two track out here and will still lets me cruise at the legal speed limit for trail connections.

    2017 500 EXC-F Gearing

    I went with 14/48 so I could use the stock chain. I saw no reason to replace it for a gearing change. The power available on this bike will allow for a wider range of gearing choices. Works good on single track and will still cruise good at 60-65 mph and will climb any pass out here in Colorado.
