i have a 98 zr 500 with a d&d pipe can and clutch kit with a 1.25 track i want to gear it down what combs should i run?

ttt anyone

Run the 19/40 or 20/39 since you have such a big track.

im with hole shot 20/39 was what it came with 19/40 is 5000-9000 gears witch with that track would probably be a good choice. if it whants to rev to much try backing off the spring on the driven clutch one hole.
