aye scottsboy just to tell ya there are other posts about clutches and springs but this is specifically about cvt trans
I actually had better results with my cvt after lightening up the clutch shoes and balancing them. It should not make much difference due to bhe CVT being belt drive but it did allow my engine to wake up before turning the CVT assembly.

I really liked the instant take offs but it seemed to be really hard on the pinion pulley.
On the Cag/Daytona Cags just use 1.5mm clutch springs so that the clutch engages when the motor is making real power, this is a under $20 upgrade that does shorten the clutch life but not by much if you ask me and at about $20 for replacement clutches, who cares.

I picked up 2 of the $300.00 special for my son and myself from Ediscountbike.com , i've been pretty happy with it , but i am a typical "Motorhead" aka speed junkie, stock sucks, yea , i'm the typical speed junkie
So far i have pulled the the insulation out of the muffler , litter louder and picked up a little faster, added a V-stack and air cleaner , now it feels like it is leaning out top end , so i bought 2 more carbs , and a jet kit so i can re-jet them , hopefully it will work a little better... but i was wondering if i could adapt a cvt tranz to my bike , the kiddo's bike is completely stock , granted i know it takes more to move heavier weight i need MORE POWER to keep up with my 8 year old featherlight son....any help would be appreciated.........

Hey, I'm considering trying a CVT bike, will this only help with the belt slippage or totally eliminate slipping. I'm about 255-260, and I've heard that there is no eliminating slippage for guys my size and acceleration will always be harder to achieve than top speed.
I put a cvt on my X-1 and it slipped pretty bad(I only weigh 160lbs). I used my dremel and roughed up the front pulley. It worked pretty well. I did notice that there was alot of belt powder after that, but if you use a finer bit or sand paper it might not be as bad. I have a shop so a new belt is right there for me.
I have read a lot of posts in here and no one seems to explain how to get your CVT to work to your advantage. The CVT is a good thing to have and if properly tuned will help a lot with takeoff and a higher top speed.
Free tip: Remove the CVT cover, buzz off the front varieter nut so that you can slide the pulleys off the shaft ( I say buzz off because if you do not use an impact you can strip or bend something by trying to hold it from rotating while wrenching or ratcheting) When you pull the varieter apart you will see that there are 6 grooves inside and 4 roller weights in there. Take out one of the weights and respace them evenly leaving only 3 back in, one weight one empty slot, one weight and one empty slot ... Reassemble and do not put the black cover back on the CVT, you will notice that now the engine screams before the front varieter allows the belt to ride up (shift) Your accelaration is now better and your top speed may have increased due to that your bike stays in the power range longer and doesn't upshift till it can actually pull the taller gear.
Under $20 mod: Same as the first mod but purchase some lighter weights from a moped performance shop, they are a standard moped size (there are some larger rollers but if the shop asks your bike takes the smaller more common ones) The stock weights weigh about 7.5 gr although I have seen a lot of variations so that is one reason why some X1s run better than others. You can get the aftermarket weights in .5 gram increments, 3gr, 3.5gr, 4 gr etc.. Now start trying different weights in there, you can use up the other grooves and install 6 weights in there that are lighter and get different results. Remember label your packages of weights because when you do mods to the motor you will increase the engine's rpm and may want to go to lighter weights to take advantage of the new power band.
It is also helpful to delay the shift of the rear spring, it seems like the stock X1 spring is very stiff and shifts about as late as you would want to but you can install shims in front of it to stiffen it up if you want to experiment.
When I modify mopeds we often install "overdrive varieters" basically the front pulley is designed so that it will allow the belt to ride up higher and give you more gear. I do not have the manufacturing capability for such a part but I am sure many of our aftermarket parts suppliers are reading this and maybe someone will put it in the works.
Let me know if this helped you and if you get good results
i have a headkit and reed kit on my bike now with other stuff, what cvt mods should i do? the moped weights? drill holes in the clutch? a stiffer spring?
Lighten your clutches by drilling ( on a drill press ) using a 5/32nd drill bit. Start out small you can always go bigger later. change the varaitor roller weights to 3-6gram and 3-4 gram weights. That should cost you about $40.00. They come in packs of 6 weights. You might ask if they have some loose weights and can sell you 3 of each This setup works great with my totally modded X-2. Also add to this setup a 17 tooth front sprocket and keep the 44 tooth rear sprocket.

why shouldnt i just change my rear to a 54 tooth? and no one by me has those weights.
