In a couple of weeks my Jonway will reach 7,600 miles, and an oil change will be due. I was planning on doing some other PM at the same time.....change spark plug (still running the original NGK C7HSA), valve adjustment (last adjusted at 2,502 miles), and change the drive belt (at oil change, it will have 6,620 miles on it). Have decided to put off doing any of it, except the oil change. Here's why. Went out for my weekly gas fill up this AM, and was happy to see that this was the 5th consecutive tank delivering more than  mpg. Last years average was  .9 mpg.....17 fillups this year have averaged 89.03......but the last 10 have averaged .4 mpg. Not bad for a Chinese 150, with a carburetor, and a 210 lb rider. Starts and runs better than ever. So I'm not going to mess with anything except the oil. "If it ain't broke, don't fix it" |

Carburetors love cool, partially humid weather, how's the weather over there? That might explain the good behaving scoot  |

Wow im not getting mileage anywhere near that, 60ish at best on my 150 I've had 100 KPG, which was about 62 MPG on my 150. That's about as good as it got for me. I have to agree about the servicing. I'd open up the CVT and check my belt and rollers, but if the thing is running strong and getting good MPG then I'd probably leave the spark plug and maybe the valve adjustment for later too. |

"If it ain't broke, don't fix it" I can understand, Kinda Be nice to know were the valves are at, be good record of a tune that may be helping your mpg. Cant screw anything up by checking it. well some may Same with the plug. She sounds like she's running darn near ideal as one may get, ey? |

I know that cool damp air will make more power, but July and August are our warmest months.....been running in 80's here lately...right at last 2 days. So it's not the weather. I don't run it hard...normally between 5400 and 5800 rpm's.....might get to 6000 on a steep pull, but I will back off a bit when it gets that high. I bought a new gates belt last winter (before I gave the old belt a good looking over), but didn't install it after comparing it's width to the old one's, 19.2mm for new, 18.08mm for old. If belt doesn't start slipping betfore totally shot, I should at least notice increased rpm's to maintain my cruise speed, as it wears....and a drop in mileage. Forget to mention that this scoot has no hotrod ignition components.....just the Chinese factory installed cdi, and coil. Oil: Mobil Delvac 15W/40 since new....changed when uncrated, and at 100, 300, 600, and 1000 miles. Then at 600 mile intervals. Fuel: 91 octane non ethanol only.....from a dedicated non ethanol pump/hose. |

UPDATE: Still ticking with over 10,000 miles racked up. Still all original ignition components, and the eleven fill ups so far this season have averaged 87.19 mpg. Valves have 7,500 miles since last adjustment was made, still read .004"and .005" at annual checkups. Still looks new, and runs much better than new.
