I worry about that with my 250sx woods bike. I run the red power valve spring and don’t wanna give up my ripper, but I’d like some lugging abilities for hard enduro stuff

​@@goinhot9133what's bad about the weights? Im trying to see what's best for my 01 yz250

I’d do a 9oz

​@@goinhot9133what does the different sizes do? What will I need for a 2001 yz250

@@sean.g4516 9oz is what people usually run, unless they’re looking to do some hard enduro, super slow, technical stuff & want to completely mellow out the bike, they might use the heavier option. (11-14oz I think). It’s adding weight to the flywheel. It doesn’t give it power, just changes the power characteristics.. so you’re adding weight to the crank, which means when the bike should “bog” down, it doesn’t bog as much and has more low end grunt, because the weight on the crank gives it momentum and helps it keep spinning, at lower rpm. Hopefully that makes sense. You’re just adding a big weight to make it harder to slow down the crank. Like when you grab traction, or something. So it will seem to have more low end power, but it won’t rev as fast or as high theoretically, because the added weight the engine has to get going.

@@sean.g4516 I’d get the lighter one for your bike if you do harescrambles… if you want your 2T to be a tractor, get the heavier weight..

@@goinhot9133 ok sounds like I need the 9oz. I jst do normal trail/woods riding, dirt roads and hay fields. So Is This something that might help with learning wheelies an going over logs?

I seen some dude use a power drill battery so i guess you could use just about anything 😂

Ahhhhh Sooooo ; Ahhhhh Merry Kan's Berry Smaht !!! 😊

Funny how those same engineers already made their own flywheel weight that you can buy and put on the bike. Perhaps it’s because different riders have different needs for their bike which are impossible to accommodate from factory alone.
