Flywheel Weight

7 posts in this topic

Working on trying to trail mod a 1998 YZ400f. I have heard that a good way to decrease stalling is to install a flywheel weight. Any recommendations on amount of weight? Thanks in advance.

I've got the same bike and use it for trail riding only. I have a 6 oz. wieght on it and it works well.

Maybe if I had ridden it longer before installing it I would notice the contrast but after putting a 14 oz on my 2000 426 I didn't notice a radical difference. The 14 oz for the 426 has been discontinued. I don't know about the 400.

That chart is what I went by for my 426 and was why I chose the 14 oz. Like I said before, the difference isn't radical. The thing is still a beast.
