I was getting ready to go into my carbs to lean them out and as I already expected the carbs are out of sync as well. I have already down loaded some material on how to do this, but I don't think it does me any good cause they are aftermarket Keihin carbs. The only adjustment I see is a screw on both carbs that adjust the slides up and down so I assume they are the air mixture screws. Where the throttle cable splits into two cables it appears to be sealed plastic so I see no adjustment there either. Any help would be greatly appreciated.
