Gotcha. I guess I'll have to wait to do that until after I rebuild my motor. AGAIN!  |

Oh definitely my man that variator is about 3/8 more take away the 1/8 and you have 1/4 of an inch of possible more belt travel. Take away the 1/16 and your talking approx 4-5 more miles per hour on your top end if you can get the belt to go up. Alleyoop IF?  |

It could be your Starter Clutch they do make nasty metal sounds like a chain. Alleyoop Boy do I hope you are right. But,... |

I am afraid it is. After assuming that I had a bad stator that was making noise, I removed the fan cover and fan to discover that the noisy sound I was hearing was actually coming from inside the crankcase. I bought this scoot in early November 2013 with 128 miles on it. On December 18th, the rod bearings failed (835 miles) and I did a complete teardown and replaced the crank, rod and piston/rings. The scoot has 1770 miles on it now and I have done everything I know possible to take care of/break in the new crank properly and this is what I get? I took some video and would like some feed back if you think my assessment is inaccurate (I hope it is).

I wouldn't think oil would do it. There are stators immersed in oil to cool them. Oil is not a good conductor of electricity. Are you sure the woodruff is cool? That was the first thing that popped into my mind. Could the pickup be scraping or could a wire be up against the flywheel inside? So I did some trouble shooting. No longer believe it is the stator. I pulled the fan cover and fan off to inspect and listen more closely. It definitely appears to be originating from inside the crank case. I am going to post a video of it with sound as soon as it uploads to my vimeo for you pros to chime in. It sounds to me like I blew another rod bearing or a crank bearing. Second one since November (original).  |

Here is the thing with putting on a longer belt. A longer belt may cause you to loose top end and here is the reason. Because the belt is now longer it MAY climb higher in the Variator BUT and here is the BUT, Due to the extra length IT MAY NOT pull the belt DOWN TO THE SMALLEST DIAMETER in the Clutch pulley WHICH IS WHERE it will turn the WHEEL FASTER. So if it does not go down as far as with a shorter belt NOW it depends on MORE RPMS with the belt up high in the Variator to GET TO THE SAME SPEEDS as with a shorter belt. So do not go with a to long of a belt it has to be just the right size to get the FULL benefit, climb the highest in the variator and at the same time lowest point in the clutch pulley. The way to determine how longer of a belt you may need IF YOU REALLY DO is this way. Measure the amount on the variator that the belt hasn't climbed USUALLY the most a belt will climb is about 1/8 or so from the edge of the Variator. You will find that a lot of variators the belt is about 1/4 of an inch away from the edge of the variator. If you find that it is 1/8 or less away from the variator that is the best belt you are going to get. But if the belt is 1/4 or more away then you have possibley some top end that your leaving behind. So if the belt only reaches about say 1/4 or more from the edge subtract 1/8 from that to allow for the 1/8 inch that should be left on the edge of the variator take that number and then subtract 1/16 from that and that leaves you with a number to add to your current belt size find a belt closest to that length. Reason for the extra 1/16 is that the belts stretch so after brake in you will have a little longer belt. Alleyoop Dammit if you don't know "everything" scoots Alley! In my initial post I pasted a pick of my Variator prior to installing the 842. Given your acumen above, does it (eyeball) look like I made a good decision having not measured anything before hand? |

Definitely seeing a slight top end improvement now.

Hey Alley! I'm in AZ. I don't think it could get much hotter than here. At what temperature should I switch from 10w40 to 20w50? If it is pushing 100 or +. Thanks! |

Oil for the crankcase use 10W40 oil unless you live in a very hot area then 20w50. AlleyoopHey Alley! I'm in AZ. I don't think it could get much hotter than here. At what temperature should I switch from 10w40 to 20w50? |

Anyone ever experience a noisy stator. It just started a week ago and seems to be getting louder. I removed the fan housing and fan for an inspection and didn't find anything. There seemed to be a little bit of oil from my leak, but nothing too significant. Would oil cause it to make noise? The noise sound "electric" and seems to dissipate as soon as I am no longer idling.

So I have put about 20 miles on the new belt. I'm a little sad to report that I am not getting any more at the top end like I had hoped. In fact, I might be 1-2 mph slower and I definitely get there slower. It's not significant, but it is noticeable. I'm sure I installed it correctly as I took my time, watched videos and follow the instructions that were provided with the belt. Anyone else install an 842 belt and experience an increase or decrease in top end speed?

On center stand which lifts the rear wheel off the ground and the front wheel is on the ground. Alleyoop Gracias Señor! |

So I installed my 842 today. I'll let you know how it goes. Thanks to Bashan for the quick delivery.

When you are referring to tilting, are you speaking of the the center stand being the axis? Does the scooter need to be on both tires on level ground to check the oil level? i take it as center stand with front wheel touching the ground. thats the way i do it at least. I check the oil this way as well. I just thought Alley was giving us better information. Alley? Clarification please?  |

? And again at 2033mi. 
..........ah boo.
