Flywheel weight

My 426 is set up for woods riding. Harescrambles. I can keep it singing pretty good through the trees but still stall when using rear brake hard(Tree). I am going to go with a flywheel weight and am trying to decide between 10oz or 12oz. I went to a rear sprocket 52 tooth and like the results but still feel I need the flywheel weight . whats working for you?

I have a 10 on mine and it helped. I would suggest putting on the biggest available, which is 12 or 14, if you are in the woods. I only do woods and did not want to wait for mine to be welded on. That's why I went with the bolt on 10 oz. Stealy weight.

I believe Scott's has a 12oz. weight that bolts on. I could be wrong but that's what they show on their website.

Thank, I just ordered a 10 oz from Terrycable.I think with the bigger sprocket already on this should do the trick. 4banger,did the 10oz pretty much resolve the stalling?


The world loves talent but, pays off on character.

I have a '98 YZ400 with a 10 oz weight, 1 tooth down on the CS sprocket, and idle set up slightly. Rarely stall...

On my 99 I have the 10.5 bolt on type so that I can take it off very easy. But if I remember correctly anything bigger requires the removal of the flywheel and shipped to the manufacturer to have the weight weld/riveted on the flywheel. That is why mine has the 10.5. But that might have changed.

I previously gave bum info. It's stroker that lists the 12oz. weight. Here's the link. Check it out if you want.
