    Decompressor

    Good night, I'm from Brazil - IomerĂª / SC
    I'm using google translate

    I made an electric start for my WR360 / 2002, but the starter got weak. So I need to make a decompressor on the cylinder, just like the KTM 300 that has a hole just above the exhaust window

    Needed more information, such as the diameter of the hole and the height from the window inside the cylinder.

    The later KTM 360 had a decompression hole-'97 I think. Do some research of the KTM 360. Excellent job with the electric start! In the vintage /left kick forum there have been threads on decompression buttons. Do a search there too. Good luck!

    R@d made a decompressor head for the 360 using a vacuum operated victa mower part, try vintage section to get ideas but you can probably fabricate a port through the cylinder head to accommodate, the vacuum signal came from the manifold.

    Wow, I just saw this.That's amazing. I think if you would have put WR300 Electric start in the title, there might be a lot more hits. Did you make your own casting? What starter does that use? The starter does appear to be in a vulnerable area, though.
    As far as a decompression modification, it might be easier to do what is done in this thread. http://www.cafehusky.com/threads/decompressor-kit-for-project-02-cr300.85739/

    updating the post ... delayed because I already sold the bike 1 year ago

    I got a spare head and installed the chainsaw decompressor and made a piece to open the decompressor by the handlebars with a very small bicycle brake lever.

    The game was easier in all situations, something I recommend.

    the electric starter I discarded ... because I didn't think it was necessary anymore.

    The new owner is happy, the decompressor works well.
