[N2ATRX]

first things first i gotta say what up to everyone on here and to all you im a newbie on here so if this topic has been coverd my bad. im a first time owner of atvs. i just bought a 400ex.

its got a bigbore kit lots of aftermarket mods to engine like cam etc. so i got a good deal i guess cause i bought it broke. this how it was explained to me , less then six hour s ride time on mods . guy goes out on pavement with new razr tires on the rear throws the coals to her in second gear goes to grab for third while the front end comes up and he said it went BANG all the sudden there is no drive from trans, or front sproket /output shaft. anyone ever here of this before? any help would be greatly appreciated .

your going to have to split the cases and examine the transmission to see what gave.

pull the clutch cover and check the frictions to see if they grenaded. Im betting you gotta split the case and fix the trans gears

if your lucky the only thing that gave was the clutch /basket in the clutch system.. if not .. its gonna be a costly repair .. and not something a first time owner would wana get into ... another option would be to buy another running motor from ebay and swap it over .. and eventually swap all your hop up mods ..
