TrailTech 33oz Flywheel

Nice machined heavy flywheel. Works as advertised and smooths out power down low. Great for single track woods riding. First flywheel I received was defective and more then likely indexed wrong. After a quick call to TrailTech I received a RMA number and had a new replacement mailed to me after they received my defective flywheel.

2 years ago
Does this kit, include a new gasket? Also, I am considering this flywheel because I stahl my 2008 crf450r on tight trails and am hoping this will help. What is the stock flywheel weight on my bike and what would be the best choice of weight for the new one? Thanks.

Q: Are any mods needed to the ignition cover?
2 years 5 months ago
I've heard certain flywheel weights are too big to clear the cover and modifications are needed. does this 33oz flywheel weight for my 03 crf450r clear the cover fine? and what is the stock flywheel weight? when i click between 15oz and 33 oz they both say + instead of one minus and one plus
