2000 Foreman 400 No Power

[croweman]

I have a 2000 Foreman and my uncles 97 goes better with larger tires to boot. I changed the plug and cleaned the air filter today. What else should I do? I need to find some more power with tires comeing soon.

Thanks

I am going to try to adjust thevalves and hopefully that will smarten it up.

I got the valves done today and was told they were a little bit loose. Now to go for a test burn.

Valves should fix it up. If it doesn't you may be low on compression. I've seen 400s eat rings pretty fast when air filter maintenance isn't kept up.
