Secret passage?

I was just on the Aussie site 400Thumpers and noticed a comment made on the '98 WR400 carb. The article referenced some sort of passage inside the carb that was reworked for the 99 and later models. It said it corrected a problem known with the '98 carb.

Anyone know anything about this?

When the 400 first came out, the FCR carb was from their street sport bike. Subsequent models have an FCR specifically designed for the 400/426. Exactly what the differences are, or what you can do to correct a deficiency is something I can't help you with. Perhaps you could do a little research and see if you can upgrade.
