It glazes from having the idle set too high, it can happen regardless of parts. You can just gently sand your pads and see if it fixes it. You should open the case and investigate before you just throw money around. The stock clutch is generally pretty decent for every day driving.

I have the Puma Romeo which is ZNEN. Same look as the Il Bello. I have put 6000 miles on it in 10 months. No problems. Other than a belt break and putting some locktite on a few body panel screws that vibrated loose. I am now about to put on a new back tire and brakes. Which is to be expected at this mileage.
PDI was done at at dealer, did not need to replace any hoses. And came with a NGK. Swapped it with Iridium and a clear fuel filter just to upgrade a bit.
I have not needed to take any body panels off, thankfully, because it looks like a pain in the ass. I found that I am able to adjust the valves by taking the seat bucket out. Though it is a bit difficult in such a small area, I think it would be more difficult and more work to take body pieces off to get to the valves easier.
The valve adjustments have held up pretty well. I have needed to adjust them twice in 6000 miles. First time exhaust had no valve lash. Second time it had closed up just .001 or so, but it was still within spec. Intake has never needed adjustment.
Oh yea, I replaced the rollers at the same time I replaced the broken belt. Mostly because I was already in there with the pulley off. The rollers had some flat spots on them, but according to the guy at the scooter shop were still pretty usable.
So from my experiance, I concur with others on this board that Znen based scooters are one of, if not, the best chinease manufacturer.

You seem to want to put stuff on this scooter or buy things when just general PM does the trick? After only 1k and the clutch is slipping? General PM as in just opening it up and giving it a cleaning normally does the trick and could be glazed pads. If it needs a clutch after only 1K I would be getting a warranty replacement instead of ordering one especially if I hadn't even opened the CVT yet?
Installing a fule pump on a gravity feed system with only 10" of fuel line instead of finding the issue?
Got a 50cc and a big touring 150cc both with more miles oin them than you have and I ride in the same hills as you do. Both with OEM clutches and fuel system and general PM has kept both of them running fine and not spent a dime on clutches or pumps, the touring is a 08 model.

Some people like to just throw money at these things for the sake of throwing money at them without doing much research and then get mad at the bike for not running right or whatever. Don't get me wrong, I love working on these things but you don't just throw parts at them the minute you get an issue, like you said most of the time its just maintenance. If you just want performance, the fuel system and the clutch are really not good places to start for your money. As far as the plastic panels...if you are not careful with them, they are plastic they will break. If you overtighten the screws on them and go driving, they will break from bumps/vibrations. Thats really just a rule of thumb for anything plastic though, you have to be careful. I wouldn't really blame the scooter.

at 1,100 miles today i switched to royal purple syn. the syn gear oil was to expensive so im waiting on that but am going to change it tomorrow with the reg. gear oil i have. i am noticing when i change the oil only about half comes out no matter what i do. i did a google earch and someone says there is the filter area drain and also a separate drain screw on the cvt side so i will check tomorrow and probably do a second oil change just to get it all synthetic and extra clean.

found that i have a oil drain plug besides the one with the filter its on the oposite side below the kickstart area but still i can only add about 425-450 ml of oil. where is the rest. yes i warmed it up and tipped it from side to side with both drain plugs open.

tried to get the cvt cover off but it wouldn't give. up by the air inlet it hits the frame so ill leave it on until the slipping clutch which isnt bad now gets to bad to tolerate then i guess ill rip it off with force? or drop the motor/tranny to get it off im guessing thats easy maybe a one or two bolt deal?

Look up a video on how to do it. It takes about 2 minutes to take the cover off, you just have to unscrew everything. If you have the stock airbox, you have to unscrew it from the cvt case before you try to pull the case off, or it will be in your way. Dropping the whole engine just to open that case would be a titanic waste of time. You also have to remove the kickstart lever, if you didn't do that. If you did all that then just pull it, and gently wiggle it until it pops off.

Have you been under filling the engine? There is no place inside there for that oil to hide. **Dipstick reminder** Do NOT screw in the dipstick to check the level. Just set it in gently against it's threads, withdraw and read. If you check the level with it threaded in, you'll be dangerously low on oil.

I'll give you some good advice and it's simple Royal Purple is a complete joke and if you want the scooter to keep running and not leaking oil you'll get it out. The oil foams when hot and allows the engine to run hotter and not lubricate as well. Don't know what you're doing wrong but the CVT cover is no big deal to get off? Here is a oil change how to for a complete novice as yourself and getting off the CVT cover also . Take note only 3/4 quart. Maybe this will help too just in case you have trouble with the clutch nut? ;D ;D ;D

thanks that all cleared it up. no issues now all is good in scooter world.
if i put in 3/4 of a quart the dipstick would be an inch above the hash marks. unscrewed. rp doesnt foam like that anymore since they changed the formula. but ok ill switch brands after another 500 miles.

over 1800 miles and all is well i use only premium non ethanol gas and currently royal purple syn. but at 2k am changing to mobil 1 syn. still have the issue when i start moving from a stop it seems like its in 5th gear(if it had gears). after several feet it adjusts itself and goes fine. im guessing its the rollers sticking ill wait till it goes to hell and replace with sliders.

You'll have to cut the end off the air inlet on the CVT cover to get it off. No big deal with a reciprocating saw, take about an inch off, then polish the cut. You need to get in there before it binds up and shreds the belt.

finally an answer from someone that understands. im just waiting for cash to do it sometime next month is it the rollers you think?

Post by ce on Aug 25, 2012 21:54:57 GMT -5
It could be the rollers have flat spots after 1800 miles, or the belt could be slipping in the clutch, or the clutch pads are glazed and the bell is slick.
Get a 1/2 inch drive impact wrench at Harbor freight, they usually go on sale for less than $50, it sounds like a lot, but it's worth it.
We're still speculating here, but to get familiar with everything, you'll have to inspect it, it gets a lot easier once you do it.
I had to cut the air inlet off mine, and then chased around a bunch of different roller combinations, the 3 14 gram and 3 9 gram wore out the 14 grams real fast, so I went with 3 12s and 3 11s, it was better balanced takeoff to top end, even though the sum of both combinations was 69.
I ended up with a Koso variator and that helped get more speed with a 115 mm fan.
Try an 835 belt if you have an 842 in there.

Flat spots on rollers don't hurt the operation of the variator except if they wear down they may not push the variator as close together which would hurt the top end a touch. If they're worn real bad it would lighten the weight which would give a faster take off and less top end. Sliders are not round and they work better than roller.
Same with a 835 belt, faster take off but will lose top end because it's shorter but it'll not help him in the Ozark hills any.
Mixing weights that adds up to a odd number which in effect your weight is now 11.5g per roller does give you the in between weight but on even equations such as 14.s and 12's the weight will be at 13g per roller and it's no better than just using all 13's to start with.
Where he rides he'll be better off with 12g sliders a 842 belt and making sure the clutch doesn't slip.

Believe me i appreciate both your advice and will dive in within a month! Ive been wanting to play with some sliders for awhile! after i get a look in there i may very well add a perf variator. ill need a reciprocating saw also or maybe just a good dremel.

friday i passed 2k miles trans still f-ed up and rear brake caliper still rattles but otherwise she's a sweet ride. switched to mobil 1 full syn 10w-30 and im pleased with the oil very expensive at 9.80 a quart. scoot is supposed to use 15-40 but they didnt have that weight. now im looking into a perf. variator, sliders and new belt. dr. pulley. and a gates premium belt.

removed the cvt cover by breaking an inch off the end with a hammer and screwdriver. yup the rollers are toast flat spots the outer plastic covering them are broke off on half of them. so now i have to spend 70$ a week in gas for my truck while i wait till oct to get the parts... please hurry parts company and redeem yourself! belt im surprised is a gates damn i forget the size allready lol and was gonna post that. cover is back on so ill have to wait to post the belt size when the parts get in. the scoot is on my porch till the parts arrive. belt looks to be in great shape though so itll stay in there for hopefully a long time yet.

what i did since i dont have an impact is used a vice grip to pinch the belt together from top to bottom and hit the socket wrench with a hammer and the variator nut came loose easily.

Znen puts quality parts in their scooters, mine is a Roketa. I'll have to agree - just bought my first scooter a couple weeks ago, a used 2008 Lance GS-R 150 with a ZNEN engine. Had 3k on it, and the previous owner seems to have done virtually no maintenance. Oil was below the low mark, rear gear case was almost dry. Engine had a weird rattling noise on deceleration. Rear disc brake caliper was just sitting on the disc with no mounting bolts. About half a dozen body panel screws were missing. Tires only had 10psi each. Anyway, fixed all those problems, changed front & rear oil, adjusted valves, changed fuel lines & filter, changed unmarked plug for an NGK, degreased everything, adjusted carb, and it runs like a top now. Really impressed with this ZNEN engine/transmission. Good acceleration, and a top speed of 57mph with me on it (~300lbs)! Have taken several 20 - 30mi trips in semi-hilly terrain with no problems at all...
