97 zrt 600. It ran great all last year. Then a lost it side hilling in the spring corn snow and the machine slid directly into a large fir tree. Hood damaged and left header bent in half (completely blocked.) I had to make it up a steep hill to get out (nobody could tow it) So, I took off the header and tried starting it. To my surprise, it ran and had power. I only ran it for 5 minutes and it was running well but loud. Then it sat all summer and fall. After cleaning the carbs and emptying the gas tank. It will now start on the first pull just like it used to but it has no power. It will only go up to about 7100 rpm. I replace the fuel filter and check all the slides of the carbs to see if they are opening all the way. They are. I used an inline spark test on each cylinder and the light remains on. (no flashing.) I used a compression test made by yamaha and I think I did it right but I am not sure? here is what I did: I wired the throttle open and took out all the plugs. Then I put the tester in each cylinder and pulled about 5 times. This is what I got. PTO cylinder is 100psi. The middle and right one are about 85 psi. What's going on here and what do I need to do next?
