My 150cc Jonway is making somewhat of a whining noise after it's a bit heated up and going faster than 30-40ish mph. It's not super-loud, but it's noticable certainly. It also only seems to happen when I'm giving it gas. It doesn't make this noise when I'm coasting.
Anyone have an idea what this could be? I'm not too worried about it, it doesn't sound like anything serious, but if it's something I could fix relatively quick, I might as well do it, if anyone knows what it might be.
Thank you!

What size weights you running? Is it that your rpm is real high?

Rear end gear noise.
Check Gear oil.. Stuff a bunch of banana peels in there.

[replyingto=chris9183]chris9183[/replyingto]Hi
Do not oil your rollers, you want to keep your cvt dry for optimal perfromance
How many miles on your scoot? a whine could be your gears, do they have the proper level of gear oil? i would check that first
Take care and ride safely
Yours Hank

While I did this I also replaced the gear oil to the proper amount since replacing the gasket meant draining it, but the next chance I get I'll inspect the gear oil section and see if maybe there's a leak. I reckon I can also replace the gear oil again, I've got a big bottle of the stuff left still. And so far, 2,400 miles. |

could it be your CVT? (usually the whining is only heard at acceleration).
