I should add that my broken v-slides were not caused by the new koso .... I have had 2 KOSO variators installed and both ate-up the guide-keys. The first actually broke off the guides and threw all the innards 'round (lasted 3 months). Second one I checked after a month and the keys were showing signs of immanent failure (removed). Went back to stock and no issues. This on a 63cc GY6 with no other CVT mods. The KOSO variators were bought May and August of 2014. |

All the gy6 bikes I have owned/own (5) and those I have serviced have this "plug". They all seem to seep a little oil.
Got over 25,000 chinamiles on one and still doing the same "seeping". Hasn't affected a thing: Just a little clean-up once in a while.
Not totally sure where the seeping originates but may not be from this "plug" al all: Maybe everything just vibrates and pools to this spot?
IDK....

Guess I'll stick to the "humping" technique.  |

Wow. Just gave me an idea. May not be a good idea; but if I get any these days I'm doing well.
Think next time I will put it in the oven for a while on warm setting. Anyone see any issues arising from this?

Just trying to help out a fellow rider, you know? Dude acted like he was entitled or something.... Still stuck in that prison mentality. Not judging: Been there.
I always run into the freaks. Maybe the ol' saying about birds of a feather.... lol
Ride on

I have set of wheel protectors and tire spoons and have done many motorcycle tires in my day,,this scooter I have here with the 13"wheels almost broke my hump doing tire change on it,,I looked like a monkey lumpin a football for about 20 minutes... That's freakin' hilarious. Been there a few times and dread it when I notice a tire change coming up. I got the 10 inch and I need medication when I'm done (for back pain-in-the-a**). I usually get about 7,000 out of a rear tire. I swear I have changed the one I ride daily 3 1/2 times. The half-time is a replacement for a half-worn and getting wobbly tire. I should be good to go for another 7,000. This bike is ridiculous.... |

Errr... Forget about it guys. Homeboy dropped a Chinese scoot in the meantime and I got it running for him. Had to replace the diaphragm (ripped), put a couple screws in the carb, drain old gas/oil, adjust the valves, adjust fuel/air mixture and tighten some screws/bolts dealing with electrical connections. Also pulled CVT and removed clutch and variator for cleaning and whatnot. Even ran a bit of Seafoam through the fuel system before refilling with fuel and oil.
Was gonna charge him $75 for everything.
He bitched and complained to the point of me undoing all I could and told him to come pick it up.
If he doesn't want to pay for maintenance on a chinascoot; forget about the Yamaha. lol
Thank you guys for the effort and input.
mopojo,
Over

lain wrote: "As far as if the fully splined ones are compatible, I would think not because the rounded area you have is where your variator and discs and belt will rotate on, ..." If the belt actually touches anything close to the crank it is the boss. However, the variator plate closest to case is not fitted for splines (smooth) and fits to the shaft snugly. I don't know if that is an issue. I will call dude and tell him to check the fan housing. the bike was buried and chained to a concrete wall. lol @ Alleyoop: 2012 he swears. The first question I asked after researching ebay, amazon and general interwebs was if he was sure it was not a 2 stroke. He rides Harleys and knows it's a 4T. Guess I will have to ride back out there and dig it out. Gotta tear it apart eventually anyway. While posting I found a video of exactly what I saw when I pulled the destroyed parts off his bike. Video says it's a Yamaha 2012 C3. No star "washer" on drive face-plate. Partially splined.   Warning: Video long and drawn out. |

Thanks for your answers, lain. I have changed a couple cranks in Chinese scoots and am pretty sure they are not compatible with Zuma. However; I will contact the merchant pointed to confirm: I actually don't know everything.... Will update as I find answers. I am surprised that there are no knowledgeable members concerning Zuma bikes here. Best bet I think is to create account on Zuma forums for this info. Again, thanks. mopojo Edit: These are the visible markings on engine case...   |

I really need a crank for a Zuma ped. I cannot find one as depicted below. All the cranks I have found are splined the length of the shaft. The one I seek is only splined partially. Are the fully-splined cranks compatible with partially-splined for change-out? Thanks  |

Friend has a 4T 50cc Zuma that crankshaft splines, variator and belt are fried. Need to replace all.
Looking to bundle these parts in a package deal with discount. Anyone know where I should start looking?

Doesn't back-fire usually indicate an air leak somewhere? I know back in motorcycle days, if a spark-plug was loose or there were any leaks around intake/exhaust, I would get a lot of that.... Sorry if this isn't any help. I tried. Also, when she cuts out, I can feel some air puffing out of the carb.
