Please have a look. Now this looks like Mouse's video. :) I hit the throttle like you did in your video and now mine looks the same. :)

Karl if you can click this link to this video you already saw maybe you can get to my channel and the latest video is called CVT TEST (Watch that one) I can't get into my channel.

I'm not seeing much wrong here - if anything?
Both sides spin up/down as usual when given the beans.

That looks better...the front looks like it starts moving as soon as you start increasing rpm's.

Karl all I did from other videos to this one is give it more juice as a faster rate. The videos before I did a long drawn out in crease in the throttle as with this one faster. I copied Mouse's video. Still I am looking now at older videos I took while traveling and noticed my rpm's were lower than compared to now.
-
The front pulley is moving and looks fine. However the rear pulley is spinning at idle. It should be stationary as the clutch pads shouldn't be making contact with the clutch bell.
This would cause extra drag on the belt while the bike is taking off and accelerating, as the engine has to rev up against the weight of the rear wheel instead of spinning freely to 3000rpm.

OK how to fix this??

I am confused cause alot of scooters spin I have seen and when I watched one of your video's Mouse at idle your scooter back tire was spinning like mine does. Here in your video Mouse https://www.youtube.com/watch?v=PVWHe0kkzD4 (https://www.youtube.com/watch?v=PVWHe0kkzD4)

It's not supposed to turn or turn alot at idle

so you have an issue to than hey? If you look at my video here does this not look normal as it spins a little and than once I hit the throttle it takes of. https://www.youtube.com/watch?v=_jIIx2BQU_c (https://www.youtube.com/watch?v=_jIIx2BQU_c)

I've just checked mine and it spins a bit slower than yours on idle. But it's done nearly 80,000km so I don't see it as a problem.

Maybe I need to take the bike on a road trip and not in town to see what it is really doing on the dash? Maybe in town is not a good way to see how it is really responding? What do you think?
-
Definitely. The transmission needs to be under load for a proper rpm test.
Report back your take-off rpm and rpms at various speeds.

OK gonna set up the camera to be on the dash properly. :) Thanks.

Just brought the bike back to the shop. He wants to put in the Kymco rollers not the knock offs that are in it now. I was looking at older video's and noticed the rpm's were a little lower than what they are now. I also noticed that as time went on the rpm's went higher and this makes me think that maybe the ware in the rollers changed the rpm's and maybe putting back in the original rollers (new one's) it maybe come back to how it was from the start? Just me thinking here.

Hooray! Hooray for original rollers! Additionally, that turning at idle probably indicates a need for a dab of grease on that needle bearing on the gearbox side of clutch.

Oh if I only knew what your talkin about Karl I would put that grease on right now! I am bright but don't know the language. :P :D :D I need to hang out with the boys at the garage.

Karl what is the original weight of the Kymco Rollers?
-
I think it is 15.5 grams per roller. De dee and others have actually weighed them.
-
Just walked back from the garage. Guess what! Bike needs help yup with the back part clutch? It isn't moving properly. He said this would cause the loss of speed. I asked if we needed parts and he said no he likely has pieces around that will work. What could be the pieces that need replaced inside this thing?
-
A slipping clutch would slow the speed while the rider would crank in more engine rpm. There are three brake shoe-lookin' things that are the clutch friction surfaces in connection wth that bowl-lookin' spinning thing with the six holes. That bowl is connected to the rear wheel through the gear box. What pieces do they have "just laying around" that will fix what they think is wrong with your clutch? Have you been having problems with the clutch engaging and getting you moving?

I have to idea Karl. :) I have had not trouble getting moving. I lost top speed as you all know and my rpm's seem high. All I know is he said he found that the back clutch was not moving or something like that. It is never real clear to me.

Probably the springs that hold the clutch pads so they don't engage the clutch bell too early.

This is just nuts! De dee, get over there and straighten those mechanics out!

Everything will work out I hope!! :D :D I have faith in them.

It seems to me, if not mistaken, you did not have these problems until they made changes to your variator....hope I am wrong....

Well my problems with losing top speed happened about 2 months before I replaced the very bad belt! It was near breaking point. I also pretty sure the rpm's were high before the new belt and or new rollers. If I am wrong the rpm's were slightly lower but not by alot. So I am not certain but don't think so.

Bike is working better from what I feel and see!!! He said something in the back bushing replaced and wasn't moving. New heavier rollers. RPMs are lower but not like you all have but much better!! Feels smoother.
-
It feels like the bike is less STRESSED! That is the best way for me to describe this. It feels relaxed now. I feel like everything is moving and flowing. RPM's have lowered I would say 1500rpm and I noticed the needle moves fluently not sticking in one spot for very long. It isn't roaring and grinding so much as it was. Everything sounds and feels softer LOL is that descriptive enough? :D He took the rollers that was in it and made them heavier (I have no idea how he did this I will ask!) and the back clutch bushing was not moving so he said. I am waiting for a a quiet morning and I will see where my top-speed sits now so stay tuned!
-
He may have epoxied some weight in each roller which should work fine. Ask him what weight target he used since some of us may want to do the same! Compliments on your description! That is a good way to describe a normal DT300i as it does its stuff around 5000 to 6000 rpm, smoothly and quietly.

I will ask Karl for sure. Another thing that stands out that was a bit irritating before was whenever I letgo on the gas to slow down the bike would jerk and it felt like I had put the breaks on when I didn't touch them now it is the same but not nearly as bad more normal like it was when I got the bike. I just found before it would almost come to a complete stop after I took my hand of the throttle.

Still Karl my rpm's are not where yours are. But I feel much better about it. I will do a early morning run on the highway with no traffic and get some readouts and see where my top-speed is.
-
Still no top-speed like I use to have. I get reach 75 mile per hour and that is it. I use to do easy 85. New filter K&N New heavier rollers (better rpm) when I reached 75 mile this morning it was maxed out 8000 rpm.
-
I once had an engineering shop put a thread into the centre of the rollers and then I tried different length studs until I had the performance I wanted.

I think a belt that is too long will give you higher engine rpm and yours is over an inch too long (if I got the dimensions right!).

OK so I need to find out what the stock belt measures. Do you know Karl :)

1003 x 25 x 30 mm.....

1003 x 25 x 30 mm.....
Oh is that 30 mm wide and 25 mm high? If that is the case mine is 25mm wide!!! and I know it isn't 30mm high!
-
No, no, NO! Length, width, angle! 1003 mm string around outside of belt, 25 mm wide ruler ACROSS the belt and 30 degree included angle of the truncated wedge of the belt you-can't-measure-unless-you-got-a special-tool-that-ain't-issued-to-gifted-painters! There ya go!

I found a measure from mitsuboshi they said it is 1004 MM. / 25.2 MM. with 30 degree wedge,
of all the belts I have bought they never met those measures, but were close, one belt came with new scooter was 1010 mm. most were 1004 mm. but were 24 mm. wide, and they all worked

I remember that! But Kat measured hers at 1040 mm! That extra 36 mm gotta hurt!

Good understand. I think mine is pretty good than. I know the width is for sure 25mm or wee more could be. I think yeah I had 104 in length. I am going to check again.
-
Yeah, remeasure a good idea. I am sure you either missed a zero: 1004 mm or 1040 mm. 104 mm would be a donut 1.33 inches in diameter!

I'd love to "bare" with you, Nireen, but it's a bit chilly here at the moment. How about a raincheck?

Hm-m-m-m . . . Well, after all that, this is what I see: "Video unavailable
This video is unavailable".
I think I'll take the rest of the evening off . . .
