I have a 1988 TRX250X I just rebuilt. It has ran great for a month now I have to tow it too get it Start. Then sometimes I can kick it and it will start. When I can’t kick start it I have tried. Starting fluid and nothing this would make me believe that’s it’s not fuel related. Checked compression 150# New valves installed and set at .004 new plug no go. When tow the bike it starts then sometimes it kicks over then sometimes it won’t. I ohm’d every wire on bike and it checks good as far as service manual. Any other help be great Thanks.
