So since I loved scootering so much I wanted to upgrade to something faster and a lot smoother on the suspension.. Here's an article about some new, inexpensive, motorcycles out now, made by the same brands that make scooters: www.allmotornews.com/10-best-cheap-motorcycles/ |

Softer spring means better performance uphills, am I right? or is it the other way around? A harder spring should close the clutch pulley harder, resulting in lower gearing much as if you had put lighter weights in the variator. A lighter spring should allow the bike to gear up faster. |

The explanation on the last link you posted is a little too high for me , lol. It says to slow down and let cool if it hits 150 degrees c which is 302f . if the needle does a full rotation an hits 10c again then that's 302 degrees. My scoot never made a full rotation , so I was only around 270 or so. That tells you something right there. My scoot had a non functional oil pump and still never hit 300f . that shows you how low these scoots oil temps normally run . this is the thing . can we get away with running at 250 or even 270+ , and the answer is yes ! But this is not the norm for these scoots and more then likely points to an issue like running lean or a bad oil pump. Like I said before , how many of these China scoots actually make it to 20k miles. One reason is because there are no temp gauges on these scoots ! And if these pumps burn out so easy , how many have a bad pump and do not know it ? And if they suspect such an issue and buy a temp gauge and are told that the 300+ degree reading is normal , well that's a disaster waiting to happen and there was no way for that poor guy to know any better. But now at least we've put it out there , and the more I search the more I find I'm not the first to do so . I really hope this helps at least one person keep their scoot from the junk yard . I agree. I posted this itistheride.boards.net/post/93687/threadLet's see if our friends here will help us all out by playing mad scientist with us. |

Our friend GEH has been working on oil temperatures and I think we should help.
It will be very easy. Just do the following if you would please.
Get a cheap meat thermometer $1-$5 that reads numbers for temperature.
Take your scooter out for a few miles of driving. Get the engine nice and warm.
Stop, immediately remove the oil filler cap and stick your thermometer in the crankcase. Leave it in there for one minute.
Please write the highest temperature down along with, if available, the air temperature outside at the time, and what you are riding, i.e. GY6 150cc air cooled. Please note any mods to your bike, and any other possibly relevant info as well, such as broken or missing shrouds, that might affect your oil temps.
Please post that info here as soon as possible.
Thanks. I appreciate your participation. I hope your effort will put Itistheride at the forefront on knowledge of operating oil temperatures for people to find on the web, as there seems to be a lack of testing and info. Let's do this for ourselves, for our friend Geh, and for the scooter community at large.

I don't think that gauge is a temp gauge , I think it show if the oil is full somehow , I'm not sure? I don't know. It looks like a temp gauge with a "token" in place of the dial. |

That was a funny post, about the metric system. BTW you can test and calibrate your thermometer in hot vegetable oil using a candy or frying thermometer just to see where it lands when temps go over 100C. yep , however it seems as if there is really no need , since the nominal temps are below what was thought. But I guess if you mean , does it read the same in water and in oil ,yes that would work. I'm sure it will read 100% the same . I mean 200 degree water will read the same as 200 degree oil right ? ,lol Thats like the whole " what weighs more ? 10 lbs of rocks or 10 lbs of feathers ? " ,lol I think those units are based on a bimetal spring or something, so they may not be linear at some point. That way you'll know, for instance, where the dial would land if the temp actually was 230F. That would be good information to know and it may help shoot down naysayers that say it can't read over 100c. You could show that it can and does, and how. |

I think some buy these oil dipstick gauges and don't realize you have to adjust some of them. Then they install them and are like " these things are junk " you put the gauge in boiling water and adjust the face to the right calibration. That was a funny post, about the metric system.

I hear of others having oil temps of 240+ even up to 300 degrees. My temps never really went over 212 degrees " and that's running hard " I was told that even 240 + was normal . my temps recently have been between 212 - 270 or so , maybe higher. I found that my oil pump is not working !. After about 20 mins of idling , my scoot had an oil temp of around 167 degrees. That is much higher then previous. My scoot usually idled around 130 degrees. I suggest all with high oil temps check their pump. Take the valve cover off and turn the engine over . you should see oil pumped into the rocker arms and cam bearings. If not then your pump is probably shot. I'm lucky I checked mine . any longer and my cam bearings would not of lasted. I had one last year. I was running just shy of 200F according to mine. itistheride.boards.net/thread/7041/product-review-tank-dipstick-gaugeI too would like to see more readings and less hearsay on the matter. Temps for Nov 2014 show lows of 55F to highs of almost 80F. Those are the temps I was riding at, at the time. |

You lost me. Are you going to try and transport 800lb of Quartz on a scooter? I think he's going to need a trailer. |

ok so I've recently had some work done to my scoot. new stator, rectifier, drive belt, rollers, battery, coil, carb, spark plug, and cdi. after getting it running fine and starting fine by electric start and kick start we tested the old cdi by swapping it out with my new cdi, but after testing and swapping them back putting the new cdi back in its having issues with the electric start. it will kick start and run.
after putting the new battery in my headlight is dim at idle and bright when holding the throttle open. any ideas on why this could be happening?
Assuming you did everything correctly, and your battery is charged, I'd be suspicious of the new rectifier. |

I've been wondering if you can do that. Cool stuff.

You got that right. An honest mechanic is a rarity. When we were kids we wanted to be artists, astronauts, and football players. No one ever said, "When I grow up I want to be an auto mechanic!"  You have never met a family of grease monkeys. I know a few in different states I've lived in, and in one family down south, the daughter was the best wrencher hands down. She could listen to an engine with the hood down and tell you which cylinder needed attention! Right. I'm sure if the parents had been computer programmers, that's what she would likely have learned and became good at growing up. It's not so much about being born to do something as it is becoming familiar with something. My cousin was a hot rodder growing up, because he liked fast cars and his dad taught him how to work on them. He became an AC tech, and insists on sending his boy to college so he can have a higher paying job. My cousin is a smart guy but college was not the family way when he was growing up. Working on hot rooftops is not fun in the summers and the pay is not so great because AC repair is a common vocation in his territory. My point is, he wasn't born to be an AC tech. He just grew up learning that hard work is "what you do" when you grow up. He could just as well have become an engineer if that's what was expected of him, or a musician for that matter. |

scooter, I disagree slightly with you. I think we are indeed born with certain skills. And if I knew anyone with a trailer, I would give them a call. Say--where do you live again, scooter?  Is that your phone ringing...? >'Kat I know what you mean. I find playing a guitar practically impossible and my drawing skills are better suited to blueprints than bluebells, but that's because I don't put a lot of effort into that kind of art. I like the piano but I find reading sheet music frustrating at best. I enjoy the art of designing things to create beauty, function, and efficiency. That's a turn on for me, and I can spend a lot of time on it without pulling my hair out. It's not that I'm a born designer, it is just that I like being creative. I like to start with a blank slate and take logical steps to create things. I like to re-invent wheels and fix things that aren't broken.  I hate working on cars. It takes a lot of patience to work on them. You have to be someone who is not bothered terribly by the heat and mess and cramped spaces and the insanity of having to take off 10 parts just to replace one part, and those are all things I detest. I just got another truck though, and I'm determined to work on it anyway. I feel it is time I took on that responsibility, and I want to feel secure about my vehicle, that it works well, and that I can fix whatever comes along, so that I don't have to rely on anyone else to do it. My luck with mechanics has not been so good so, once again, I am forced out of my comfort zone in order to find comfort.  |
