ok, the 3rd gear is the weakest gear. that's why you can break it!!! 2nd gear is the best gear to use. unless you have a clutchless trans, you don't shift gears in water box!! herb mccandless said never use 3rd gear for burnout! I ran 833 for 32 years, did burnouts on every pass, now I have a jerico. still use 2nd gear.I did break a few gears in 833, but trans was raced a lot!! I can count on one hand , times broke the 833.
