    most racers say every 20-25 pounds equals a tenth so i would think 50 pounds is equal to 2 tenths.

    My experience was 25lbs/ tenth. I was running 9.01 and put a buddy on my bike that was 100 lbs less and he went 8.61

    10 hp = 1 tenth and 25lbs = 1 tenth. Also depends where the weight is located.

    I can also say the whole setup for chassis and clutch was wrong for a guy that was 100lbs less than me. He could have had more with clutch tuned for him

    Rules of thumbs are for people who can't do math. 50lbs doesn't matter much on a 800hp machine, but a 60hp twin would have a massive difference.

    Further, are we assuming the bike is deadly consistent and that the tune is adjusted for each rider, with both riding it exactly to the limits of what it's capable of doing?

    Theoretically lol rule of thumb, bottom line build your set up for you and push that machine to the limit to beat the guy in the other lane this question has too many variables
