Hey all! New to here but not to quads. I’ve had a few 400EXs over the years, a couple of 300exs and now a Frankenstein 03 400ex and a 05 TRX450R.

Thanks for the add! Also if anyone can help, I’m looking for mainshaft 2nd gear for my 400ex. Thanks in advance!

Unfortunately Honda discontinued the gear many years ago (#4 in the breakdown) - the only way to get one is from a parts donor vehicle - you might have to buy a complete EX to get what you need and part out the rest of it or switch engines to an 05 and up.
