That could very well be the case. That belt is 8 years old, and may be showing it's age. I suggest that it's time for a belt inspection. Look at the how to section in this forum on belt replacement. It tells you how to pull the cover off and take a look. If there is any doubt, replace it. One of our members had a belt let go at similar mileage and was stranded many miles from home until he could get it replaced.

I have noticed it so far when I gun it to either get on the highway or if I'm cruiseing along at say 55 and gun it up to 75...it slips and then kind of winds up suddenly...

If the belt is 8 years old I would replace it. I'm sure that the belt is like tires where age effects it too. But this is just my opinion. You might also check the torque of the bolt that secures the variator. If it is not torqued as much as it should that may also get rpm's to rev or feel like the clutch is slipping. Just a thought.

Worn driven face spring ,is part of the clutch .Just different terminology .

I've noticed a drop in MPG lately. I have had the J-Costa installed for about 8K now and I'm thinking the pins are wearing down, need to look at them. So here soon, I'll be going back to the Stock Honda variator. It's like new with only 2K on it and planing to use a little dry lub (graphite) on the rollers to help them on there mission.

I'll let you all know what I find out about the J-Costa pin wear. Does anyone know what the wear limit is on the J-Costa pins?

Yeah, The whole darn thing needs to be taken apart. Would not be so bad if I had a M/C lift. Working on the floor kinda gets to me after a while. This will give me a real good op to measure the belt to see how it's holding up.

Thanks Guys for all the information.

Max, I'll head on over to Wal-Mart and pick up a small can of SEAFOAM and try it out. There's a PGR mission on Friday I'd like to Attend. 220 miles, one way. Give the scooter some sweet, high speed, highway miles. Just changed out the oil and filter...went with a full synthetic oil on this change. Motor sounds a little smoother on the full synthetic oil.

Dang right it sounds a little smoother. Everyone knows that full synthetic will result in a pleasant aural tickling. A blend is not quite as soothing. And full dino oil is just so hard on the ears. My friend the symphonic tympany artist told me all about this years ago. He claims Shellbil 7 will make your motor sound like Beethoven.

Not even related to the drive belt until I add I think that the kevlar belts sound like cellos. OEM are more like violas.

There we go.
Spoken like a true believer in not only the Zen-like lubricating abilities of engine oil, but also the aural rhapsodies of distillated and hydrocracked petroleum circulating inside the Honda 582 cc parallel twin double overhead cam 4 valve per cylinder engine.
Whew!

My gas mileage always drops in the fall . They run richer longer . Maybe it is still warm there and that is not it . I am wearing double layers already .
those belts always look the same I have two used ones on my wall one is 02 the other 06 both changed when light came on ,both look like new .
i think the belts would last a lot longer to bad the variator is crap . So I replaced my friends drive belt for him ,I told him to make sure he got a Honda belt so he did . And printed on the back of it ,MItsubishi . What the ?

Simple explanation for the Mitsuboshi markings on the belt.

That's who makes the belt. Honda doesn't manufacture (among other things) the belt, light bulbs, spark plugs, tires, etc... They use suppliers like Mitsuboshi, Sylvania, NGK, Bridgestone / IRC, etc.

J hear ya on gettting down there on the floor and working.

While you have it apart, don't forget to deglaze (take the shine off) the front variator pulleys. I use 400 or so grit paper/ your choice) This helps with slippage.

Hey sounds like you'll be doing a lot of stuff I'll probably also be doing at some point. I too want to add a better horn and add some extra wires and, when I can afford to, get Hyperpros.

Maybe we'll do a garage day somewhere. My garage is tiny and cluttered so it just gives me enough room to fit my Swing while the car sits outside.
