How do YOU shift gear under hard acceleration ?? I bet 90% of you who moved recently from road to dirt do just like I do (or did). You accelerate in 2'nd then quick as a flash you do all the following in combination as fast as you can: lay of the throttle very slightly, clutch in, shift to 3'rd, clutch out, on with the throttle. Going fast yet ? Satisfied? Got enough HP for the kicks you like ? If NOT then the next bit is for you. DONT let the throttle off AT ALL when shifting. Keep it wide open for ALL of the acceleration. And do exactly the same shifting procedure as quick as you can. You wont ruin your engine. You will need new underwear. Just make sure you have enough room to brake. See how many free horsepower you gained ? The difference blew me away, even though I thought I was shifting fast before.
