07 trx450er

Hello. I adjusted the valves on my 07 trx450er last year and it ran really good. I shut it off and it was turning over really hard. Only had about 1 1/2 hours on it. I'm new to working on it myself. Any advice would be greatly appreciated. Thanks

So you are asking what could be making it turn over slow? You've only rode it 1 1/2 in a year? Sure battery has a good charge to it?

Sorry... Yes I am asking if anyone had this problem. I dont want to pay someone $120+ per hour to drag their feet working on my quad. And yes I only rode it about 1 1/2 hours. I dont have much time to do fun things. So I did buy a new battery but it still turns over hard and slow. Ran great then the next time I tried to start it this happened. It reminds me of when you have the distributor turned to far in a car. If that helps lol.

Check the decompression adjustment. Valves have to be shimmed before you set decompression and the best way to do it is with a compression gauge and the valve cover off. 60-65 psi is the sweet spot.
