..poppin' wheelies!..

...I'm not sure..I shoulda asked...I will when they open up this morning..

I think it is rated in rpm's.  I saw some online listed that way.  I just don't quite get how that rating works.  My guess is 1500 rpm's before the spring starts to compress and the belt begins to pull the torque drive open.    Not sure, it seems it would be co-dependent upon the variator and clutch springs.

Thanks guys. I am looking for a good place to get my parts, I found that dealing with the same supplier for all my parts has been a good idea, but my last one doesn't deal much with Kymco and doesn't have much selection in tranny parts. I would like to get a good clutch. I don't need to go over 50 just want to be able to maintain 45 and accelerate pretty quick, but want to keep the revs as low as I can for longevity. I drive my scoot everyday and plan to except for when it's raining.

..malossiusa.com is a great source..most of us down here in the 50 boards are partial to the malossi products..

..the thing is, with these 4-strokes, the key to maintaining speed and quicker acceleration is getting those rpms up..

..unlike the 2-strokes, 4ts tend to ease into the power band, without any mods...

..I bought my A50 new in December of '07..been riding it virtually every day since... I now have close to 38,000 kms...

..keep your oil changed often, valves adjusted and just some general tlc on a regular basis, and your A50 will last you a long time...

peace

..They told me that the rating was in pressure...psi...fully compressed...that the stock spring is @ 750, the white malossi @1000...imma gettin' a 1500...

..still I wonder...

[Shaka]

That rating in psi is not correct!  Relating mountain bike suspension springs which are rated that way.  An example being I have a 400 lbs by 2.75" stroke spring on my mountain bike.  That is a burly spring, which I cannot compress by hand at all!  It takes 400lbs to compress it 1"!  I can compress my stock clutch spring relatively easily with both hands all the way!

I'm gonna go ahead and guess, the ratings are similar to the colors on the shoe springs. Solely for internal use to Id. to product. I saw the psi post, and it just didn't seem right. You were right to wonder. I remember reading something about the density of the steel or the alloy used. The stronger spring is made of a different material to allow longer life in a heated environment. This may be more along the line of the "rating". Pretty soon we will all be Professors of scootology...or some such. I generally deal w/ 30ish people a day, and not too many of them get me thinking. Thanks guys!

..I have my old spring...pre-malossi..I can compress it fully with my hands...

..now, imma big boy, but I can't see me compressing 750 psi in my bare hands...

..could it possibly be a metric pressue rating??...

..so, this spring keeps pressure against the pulley, and a stronger spring does not allow the belt to slip as much...

..what is the force that causes the torque drive to let the belt ride lower in the pulley..

..what actually causes the pulley to open, and compresses the spring..

[zombie]

That would be the rollers/sliders in the multi var. The force of the spinning weights forces the ramp to close,and the spring in the clutch controls the recoil on de-accel. It truly is a balancing act.

[Shaka]

So, the amount the torque driver opens/closes is co-dependent upon which weight rollers in the variator, as well as the stiffness of the main clutch spring.  It truly is a balancing act!  The CVT is a very impressive design, so cool!

...I can see where a Kevlar belt would be beneficial...

[zombie]

Besides the wear factor. The biggest benefit is the LOW stretch. You don't have to wait for the belt to "catch up", And you will notice the rubber compound has a sticky feel to it that give another benefit. I installed all my cvt parts together about 2 1/2 years ago (14-16km) and am thinking of replacing the rollers, clutch springs, and belt this month so I can take advantage of the free shipping, and 10% off from Malossi. I alway like to fix it before it breaks

I'm not sure if I went to the right malossi site. I went to malossiusa.com and couldn't really find any agility 50 clutches and variators. can someone post a link for me.
