Sorry to inform you but it has a clutch.

Congratulations, it's good to see young people getting into the hobby.

You've come to the right place!

Here is a link that should get you started.. Getting a Qt50 roadworthy .don't forget about crank seals..and step 1 should be to get some greaser on that engine and clean it up to prepare for surgery

Also between seals, and tires/tubes, and gaskets be prepared to spend over a $100

A very mundane purchase, but it's needed. (edited)

Re: My first moped 1984 Yamaha QT50 Yamahopper

um... there is not a manual clutch... just a wet centrifugal clutch that is automatic

Re: My first moped 1984 Yamaha QT50 Yamahopper

Not going to open everything even though i already know how to. It's been sitting since about i think 1985. If the crank seals were lubricated good before the thing sat i think it will be fine. This is also a quick flip for me so I am wanting to make a profit with this

Nobody said it has a manual clutch. But in your video you said it has no clutch. Just making sure you knew it does

Since you're new here and young I'll let you know that there is a general disdain for moped flippers here .... especially ones that intend to half ass an engine repair by neglecting crank seals...

Not cool. . . .

Re: My first moped 1984 Yamaha QT50 Yamahopper

"So old and vintage" lol... These are more complicated than they look, there is more to making it fast than just a pipe, if you intend to re-sell it, just bring it up to stock specs. They are well made, and worth redoing, this is nothing like that bike kit thing you have, for resale make sure you have title or can get one if it is needed in your area, there is not a ton of money in mopeds, it may be more fun to just clean it up and enjoy it, have fun.

So when you buy a moped restore it, then sell it to buy more mopeds you are a "flipper"?

Restore it.....yes all restorations begin with neglecting air leaks.

if it burns oil from the clutch side, you need to replace the right seal. if its really hard to start, left seal may need replaced. more than likely, its a good idea to replace them because they probably have never been changed.

Re: My first moped 1984 Yamaha QT50 Yamahopper

lol i dont care at least it worked

Re: My first moped 1984 Yamaha QT50 Yamahopper

lol

Re: My first moped 1984 Yamaha QT50 Yamahopper

yeah, i have the title already. just waiting for paint, then i'm going put it back together ride it for a bit, sell it, then buy another moped or motorcycle

Re: My first moped 1984 Yamaha QT50 Yamahopper

Awesome thank you might as well change both of them need to check what tools and and how to replace them, thank you again

flywheel puller, proper JIS screwdriver or similar as stator screws will strip easy, piston stop, torque wrench for left side.

piston stop, torque wrench for right side. keep all the parts from right side in order and/or take pictures as you disassemble. new right side gasket as well.

Re: My first moped 1984 Yamaha QT50 Yamahopper

Awesome sauce! Thank you for the heads up!

Re: My first moped 1984 Yamaha QT50 Yamahopper

I know I'm kind of new here, but isn't a moped a bike with a 49cc MOtor and PEDals?

As I understand it, both a 1905 Harley-Davidson Model #1 and a motorized bicycle are technically mopeds by definition. They are not however mopeds by the laws in the state I live in. Nor is a Yamahopper. :) (edited)

Re: My first moped 1984 Yamaha QT50 Yamahopper

Every state is a bit different, in MN, a Yamaha Qt-50 is classed as a moped, even though it isn't. :)
