The bikes starts, idles fine, when drive line has no pressure (like on the block) it runs fine. As soon as you put pressure on the drive line it bogs out, but keeps running. It will not move. I've replaced carb, reeds, exhaust system, piston and rings, stator plate, key switch, and all the bearings in the final drive shaft. Also, the Eton dealer cannot figure it out. Does anyone have any suggestions for this problem?

 

Are the rollers in the variator installed properly?..It sounds like it might be something in the transmission instead of the engine...Do the rear tires turn freely?...I would pull the belt cover and take a look in there.

 

Yeah what oldyeller said also to un bolting the exh. from the head and see what happens

 

Remove the spark arrestor from the muffler.
they get clogged and restrict the muffler. Just like the banana in the tail pipe trick.

 

It does sound like it could be a clutch issue. If the torsion spring has taken a dump on you that is pretty much the effect. Also if your rollers are deformed or wedged in the front clutch, that could be the result. I'm assuming that you or the dealer you took it to checked the compression.

 

yes i rebuilt the whole motor plus put brand new exhaust new pistonand rings bearings reeds carb cdi stator plate and key switch.

 

2006 Eton 90cc 2stroke

My rear centerfuge clutch would not engage. It would grab and as soon as it loaded it would let go. Bike would hop but not move. New rear clutch, New Variator, New Carb, New Coil and Plug, New piston. Large amount of smoke at all times. I finally found the problem. The rear spark arrestor was fully plugged. Cleaned it and reinstalled. Bike ran and engaged great for about 30 seconds until the spark arrestor clogged again. The exhaust pipe/muffler is full of oil/debris from the spark arrestor being plugged. Need to remove exhaust pipe. Clean and reinstall.

Hope this helps someone else. Pull the spark arrestor out of the back of the tail pipe. See if it moves after.

 

No offence, but we would have told you that long before all the money spent.
