I picked up my new variator parts late friday. (Both pulley halfs). I will install everything tomorrow. I have new stock rollers and such. But I am going to install my used original belt. I can not see taking a chance again with a new belt as of yet. I down loaded the work shop manuel, and it is strange, but it does not say to put a dab of grease on the inner side of the inside/sliding pulley half? The half that the boss go's into/inside. I know both of my variators had a small amount of grease on the boss. Just a little, but it was there. So this seems strange? The rubber seal on inside pulley half is stated as a dust seal, and not a grease seal? Seems as it would or should be a grease seal? Oh well. I will put on just a dab of grease so it will/can break in right. And then slide the boss back and forth, and then wipe off any excess. I am going to super clean everything, and then install. What is any body's thought on the grease? Yes or no? This time I know everything will be correct as I have studied video's and the manuel, and talked to Kymco mechanics, and Chet from Kymco USA. Who is a great guy by the way. Wish me luck. :-*

What did kymco usa said about grease?

My thought is the dab of grease is assembly lube there for the protection of the seal only. It's commonly instructed to use this on a new seal. It's not for the metal parts in my opinion. My new parts came dry except for a dab on the seal. I have a little bottle of assembly lube left over from an engine rebuild I did a while back which I use from time to time when putting new parts in. It's not meant to be permanant lubrication -- just to help get things going smoothly like breaking in.

I talked to Kymco before I could get the manuel down loaded, so we never spoke of it. I know it had some lube on the boss as I could see it. I have not taken the inner pulley half out of the box yet, (its still in the car), maybe it comes pre lubed? I will let you know. But Kymco and the manuel do not talk about grease. So I am thinking since the boss is steal, and the pulley is alloy, maybe it's not needed? Hoolander makes a good point about the rubber seal. Maybe that's all it's for, (the seal)? If it is not pre lubed, then I will ad a dab, work boss back and forth, wipe off excess, and install as per manuel. And then all I can do is ride it and hope it does not do it again. I'll keep u all up-dated. :-*

Went for a hundred mile run, so far so good!

After everything you have been through i am truly happy for you.

I forgot to say, Hoolander was right. The inner pulley half, (the one that slides on the boss) comes in a plastic bag and has a very small amount of grease on the rubber dust seal to protect that seal and not to lube the boss. So there is no need to grease anything! Like I am saying now and for ever, follow what the service book says and leave it stock. I'll ride it 500 miles or so, take a look at everything, if ok? I will install a new belt and leave it alone! :-*

Road about 120 miles today since it was my wifes day off. Average speed 55-60, with a little in town riding. Everything was perfect. RPM's about 500-750 less than the one gram heavyer Dr Pulley's? Makes no since as the RPM's should have gone up? Something smells bad about my Dr P's? Got about 53-54 MPG two up and loaded! Not bad for a carbed model. :-* ;D
