I have a 99 wr400fl that has cracked the carb slide plate .The carb body(fcr) looks fine as do the rollers and the o ring is in good shape and has been replaced as well.Anyone have an idea or experience why this happens?Twice on this carb ,the last plate only lasted a couple hours.

It's common on older model carbs. Do a search, this was covered recently.

I have replaced mine twice in the past five years. Do a search, I don't think anyone has a definite answer as to why this happens.

I replaced the original carb with one off of a WR450. Works great. No cracking yet.
