clutch problem for a 1986 spree

Post by apephoto222 »

Does anybody have a clutch for a 1986 spree for sale.

I am looking to change mine cause when i go for a ride and the clutch gets warmed up and then takeoff for a light it seems to be bogging the engine and you can feel some shaking or something like that.

would anybody else have that problem and would you have a clutch for sale?

Thanks,

The simple question is, is your clutch all worn out? Is the pad material down to almost nothing? If not...

1. Remove the clutch assembly and inspect the parts. The first thing I'd check is the clutch pads and see if they're worn down, then inspect the clutch bell for any unusual or excessive wear.

2. Inspect the condition of the belt. When the belt is worn, it is "skinnier" than it should be. When the belt is worn, the belt doesn't ride up high enough at the front pulley and sits lower than it should at the rear pulley. The effect at the front pulley is minimal on a stock bike, but the belt sitting deeper between the rear pulley means it is going into a higher gear much too quickly, resulting in the kind of acceleration similar to a manual trans car when you start off in 2nd or 3rd gear from a dead stop.

* The opposite is also true, when you have a brand new belt, it'll tend to be a bit wider than normal... this results in the bike acting like it's in a lower gear longer than it should, so the engine may appear to wind up more than usual, this is normal until you break in the belt properly. The effect is similar to lowering the weights at the front pulley or going with a stronger center (torque) spring at the rear.

The shuddering you're feeling is a symptom that can be caused by many things.

- carb problems (dirty or need of rejetting), results in lower fuel delivery and poor power (lean on fuel)

- clutch pads not making full contact with the clutch bell causing slippage

- clutch springs worn (causing the clutch pads to engage too soon and too low of an rpm under load)

- worn center spring (torque spring) which is allowing the belt to be drawn in too quickly into the rear pulley, making it go into a higher gear much too soon

If the engine appears to be feeling dull like it's not revving up as much as it did before while accelerating, the problem will most likely be due to the center spring being worn down.

Clutch springs, unless you race hard all day and all night everyday and night, will usually last as long as the life of the clutch itself. If the clutch is relatively new or only slightly used, then I'd suspect that the clutch springs aren't the issue.

Clutch springs usually last as long as the life of the clutch pad material so it's very common to see them both thrown out and both replaced at the same time. If the clutch pads are in decent shape with a decent amount of padding material left...

My best guess would be that you have a possible combination of a worn belt and/or center spring.

does the clutch come off easy. I have taken off the clutch / belt cover and i see the clutch but i am wanting to be sure that you don't need any special tools to put the clutch back on after i take that one nut off the center of the clutch.

Greetings:

The clutch assembly should slide off the transmission shaft splines without difficulty. You should be able to immobilize the axle by locking your parking brake on. Other than a 14mm wrench or socket, No special tools needed. Good luck!
