    94 Waverunner 701 twin carb / carb settings

    Can anyone save me some time and give me standard screw specs for the 94 raider twin carbs. Some one has kitted the carbs and now she backfires hard but the reeds are good so I suspect its screws, leads or worse.... air leaks.

    Here are the specfications from yamaha tech bulletin# wv-97-008A Main jet # 130 pilot jet #67.5 screw settings are low speed 5/8 turn out from lightly seated closed position + or - 1/4 turn on BOTH carbs. For the high settings 5/8 turn out on the FRONT carb and 1-1/8 turns out on the Rear carb + or - 1/4 turn from lightly seated closed position. I know the setting on the two high speed adjustments seem odd that they are different but this is correct! Tommy Jordan
