Default Clutch Problems on Foreman 450 S (1998)

I'm losing power when I switch gears. I'm getting higher RPMs and finally the power will come. This problem is worse when the machine is cold. How should I troubleshoot?

Does anyone have any idea how much this will cost to replace? Do I need to replace or rebuild both clutches?

Any help would be appreciated.

Thanks,
bd

Have you adjusted your clutch?

Nope. What does that involve? I've read through the Clymer manual a bit, but haven't really dug into it. What should I be looking for?

Thanks,

Should say in your owners manual and the clymers how you adjust it.
Its really easy to do.

On your front engine cover you will find a nut (14mm wrench fit) with a screw on the inside. Break loose the locknut and turn the flat blade screw inside counterclockwise (as if to loosen) until you feel resistance, then back in one quarter turn. Tighten the locknut while holding the flatblade screw from moving.

It's unlikely your slippage is an adjustment problem unless somebody was messing with it and the adjustment screw is too far counterclockwise. You should check it anyhow. Sounds like your manual clutch may need fresh plates. It's unlikely both clutches need work.

If your other (the centrifugal) clutch is slipping it would be most noticable at take off speeds, and going down hills you would have sporadic or no engine braking (it would freewheel).

I'm guessing around 250-300 parts and labor would be the average. You should get it fixed promptly though...you don't want that fiber clutch plate material floating around your engine. In extreme cases, it'll wreck your engine.

Ahh, exactly what I was looking for. I've already got it in the shop, but needed some unbiased info. It seems to engine brake fine downhill and starts off well too. It really loses power from the second to third on up. I'll get the engine RPM response from the throttle, but the power doesn't kick in until the machine increases in speed.

Thanks for your help and I'll update the post when I hear from the shop.
