Hi all. First post here. I bought a trx250x recently and went for the first long ride today. nothing crazy hard or fast as I had my kid with me. The quad seemed like it was starving for fuel then died. Removed cap and checked fuel was ok. I switched to reserve and no change. Switched back to normal and fired up. Drove for another 5-10 minutes and happened again. Let it cool down a touch and she would fire, this time it died quicker. Pulled the plug and it seems nice and light brown. Going to change it anyway due to not knowing the age. any help would be appreciated
