Today on my '97 XLT SKS, I went to check if I had air leaks on my sled. While sparying my carb boots and my PTO seal, on the seal and one of the carb boots, the RPM lowered a little, maybe 100 RPM. Now, doesn't if you have an air leak, the RPM increases? Just wondering. The sled runs great though, just a high idle problem after riding it.
