We have two 99 GSXL's that were running decent, but not great (6500-6600 RPM). After doing some reading on here, I changed the spark plugs and cleaned the raves. Now, one of them runs about 6600-6700 rpm, and the other one runs terrible. The bad one runs 6000 at best, and usually closer to 5700 - 5800 rpm. If i hit any waves, it drops back to around 5000. We thought we did something wrong when re-assembling the RAVES or got a bad spark plug, so we swapped both the raves and spark plugs between the good and bad skis. No change, the good ski still runs good and the one running poor continued to run poor. We also swapped the computers, so that is ruled out as well. It also spudders out of the hole, but it has always done that. What should I check now?
