Worn secondary clutch buttons?
A stock 250 should have around 120 psi, so you are good at 115.Thanks for advice, I will look into that possibility. Is the 115 psi compression ok?
Buttons are slightly worn, belt has a little sheen on it. Going for a secondary clutch rebuild, new belt as well. What do you recommend to maintain carb?I agree, look at the clutch. Give it a GOOD cleaning and service the sheaves. Look close at the belt.. it should NOT be shiny.
If your convinced its the motor, have you cleaned the carb? Do you run anything to keep it clean?
Glad you found the problem. Time to give 'er hell!!!Thanks for all the helpful advise. I did a complete secondary clutch rebuilt, and installed 42 tooth sprocket. The quad has never had so much low end. I believe the buttons were the main cause, but wow. AWESOME! Thanks again everyone!
