Ok I did something that fixed it for me. I opened the variator area up. Nothing looked wrong. Took off variator, same thing, nothing wrong. Decided that I'd like to try mixing sliders (13g) and rollers (14g). Then I noticed that when I would go to put the variator back together and the belt back on the belt would push the variator back some. I used right hand to get the belt to have more play and then put the belt and variator fan back on. I then tightened the but by hand as far as I as I could. Used the impact the rest of the way. It's great now.

Now if I can figure out why the gas mileage is only 60 mpg.

I have a 2013 cali classic 125 cc.. I replaced the previous belt and sliders. I did this because the dealership have dopes running the place. They put a belt that was too long, and 13 g sliders. I just need normal performance. I just wanted factory oem stuff. They couldn't get it very quickly and didn't think to have anything in stock for the scooter I purchased from them.

Anyway, I got a Bando 799-19-28 belt and Dr pulley 14 g rollers. I can get up to 55mph again and gas mileage is up to 73mpg on a windy day. Yes! I couldn't get past 53 mph before and gas mileage was 60 mpg on a great day., no wind.

I now have a excessive vibration from 25 mph to 30mph maybe 35 mph. Also, there is a sound that comes on about 30 mph behind the vibration that stays until past 50 mph with a slight vibration constant. The sound is that of car tires on a highway. The highway sound of tires. It's the only thing it sounds like to me.

My questions, well the vibration subside? Week the vibrations decrease? I'd it possible the Dr pulley rollers are incorrectly faced and/or is the belt the problem? I need to emphasis that I can go 55 mph and faster again, and my gas mileage is much closer to correct.

Thank you all

Got a new 2013 lance 125 cali classic. Awesome!

I'm going to try removing the emissions. It's the wrong color it should be black smoke. It's white. I'm going to put the valve cover that came with it back on. Get an egr blocking plate. If that corrects all this fine. If not, then I'll tear the engine apart

I put the head cover back on it runs fine.

I hope this helps. I took off valve cover. It won't start with it off. It turns over but no start. What could cause that? seems compression isn't being achieved without valve cover on.

Ok, so it's still burning oil, mostly on slower speeds. I'm going to run out a slow speeds this weekend for a distance.
