Engine Whinning

Both rear bearings should be lubricated by the grease that is between the output sprocket bearing on the left and the clutch bearing on the right. If you remove the clutch cable adjuster sitting under the carb, you can put some grease in there to lubricate the bearings.

Awesome tip!

Yes, you should put some wheel bearing grease or lithium grease in there.....just a little, use a toothpick to put it all around the big gear.

Thanks guys, I never heard of that before. I can't really picture this but I will remove the part mentioned and try the toothpick thing.

You use a toothpick to spread the grease evenly...if you just cram a whole bunch in there, it will get spread around the gear eventually, but it will make a huge mess and end up in the clutch plate.

Good idea on the toothpick - I've been using a chopstick!!

The only thing I'll add is - for the clutch gear lube, use a sticky, sticky grease - even boat trailer grease (nasty as it will ever be). I use a homemade grease/tackifier concoction. The main reasons are as BGJ says, the grease will leave rapidly so you won't have lube and will migrate to the clutchy plate and pads.

Toytime, just to be clear, what Pablo and BGJ are talking about is actually applying grease to the teeth on the clutch gears. Which should be done. But what I was trying to explain was greasing the ball bearings behind the clutch plate which cannot be seen unless the clutch is completely disassembled. Again, remove your outer clutch plate and there should be 3 small small holes about half way between the center and the teeth. This is where you can grease the little bearings. Both of these areas should be greased.

Thanks, I understand. I will remove the clutch plate as well as the little clutch cable adjuster under the carb. I just can't picture how the grease will get over to the bearing on the left side (the front sprocket for the chain).
I guess it may sound like I am too worried but the thought of these bearings running dry scares me. As I said above, I always figured that some of the two stroke oil would get in there. One thing is for sure, if I was building these engines, I would have dealt with this issue by providing a grease fitting or even one of those spring loaded caps that allow you to drop a few drops of oil inside like most electric motors have.
I love and use my bike every day and would die without it all because I did not look into this.
I wonder how many users have never even lubed this area and for how long.

If you get grease on your clutch pack you won't be going anywhere real soon!
A dry clutch don't like grease, or oil or any outside matter.

Took clutch cover off. The part that is spring loaded. No, three holes. I have the square clutch pucks.
