Last night I was driving my 500 indy and I got it stuck in the snow. After I got it out I slowed down a little and when I tried to pull the throttle a little bit, it made a weird clicking noise. I pulled the throttle a little harder and the sled took off. The rest of the night I never heard the noise anymore but the sled couldn't reach high rpm or top speed. When I hit the throttle it had very little response compared to before. Any ideas on the clicking noise and rpm issue?
