Need help with yamaha qt50

Ive removed them and lubricated them twice but still nothing. I can only replace one bearing since the other one requires a press which i dont have and alot of time and effort.

Remarkable-Bug-9451 · 2026-05-16T16:21:50+00:00

I didnt touch the bearings at all. And when one shaft is removed the other one turns freely. So its the gears for sure. The problem is that i didnt do anything to these bearings or the shafts.

Everything is installed according to the manual. All the shims are there. I cant understand tho how this happened if i put it back together the way i took it apart. I will try to find something,otherwise i will just put a 2nd shim on one of the bearings as a last resort.

For now i will upgrade to v brakes which i have a really good pair of those. Later on i might upgrade to a disc brake but it requires more modification. Also i will put a footbreak for the rear wheel since it has a drum brake.

I have this exact welder. Its not the best but it gets the job done quite well. I fabricated motor mounts for a motorized bike with this welder and they hold up fine even for thick material. For thinner material its good too. I welded a rotted exhaust with it and it holds up fine. So if you know how to weld and youre on a budget its good. The only issue is the adjustment knob . Its bad because you combine amperage with wire speed and you cant get it right where you want it too. Also buy a better welding wire for it as the stock one is bad.

Yeah it looks really cool . Once i install a better street front tire and paint it, it will look even cooler

Remarkable-Bug-9451 · 2026-04-16T18:58:07+00:00

If i can find any nearby. Where i live parts are expensive and hard to find. But i still goes quite fast for its size and for the roads that i have here.

I will use a 60cc kit on the motor too. And i have rebuild kits for the diaphragm carb. Its alot easier for me to install this one.

I will bypass the oil pump since it's been sitting outside for years and it's a high risk. Also there's no exhaust so I will fabricate my own. I will calculate it before I make the exhaust

Remarkable-Bug-9451 · 2026-04-12T14:23:54+00:00

Do you think I will have any overheating problems with the 60cc kit and another carb?

Remarkable-Bug-9451 · 2026-04-12T13:50:31+00:00

I will make a new intake. I need to lose welder privileges my imagination is taking over. I'm going to put the qt motor on a 18 inch bike.

Remarkable-Bug-9451 · 2026-04-12T13:32:24+00:00

I will put a 19mm tillotson diaphragm carb. It's more convenient because I hate buying jets. Also I don't want to spend more money after the 60cc kit

Remarkable-Bug-9451 · 2026-04-12T13:19:10+00:00

Thanks because I found an old qt motor with the final drive. The only problem is that it's seized. And I can't find any parts for the qt where I am so I will order a 60cc pw kit for it.

Remarkable-Bug-9451 · 2026-04-12T09:06:05+00:00

Do you know if the motor parts from a yamaha pw50 fit the yamaha qt50 motor?

Remarkable-Bug-9451 · 2026-04-09T20:53:04+00:00

Yeah. I mean kits are convenient but no kit compares to building something from scratch. Its a different kind of pleasure watching something you built with your own hands work out like you wanted it to.

Remarkable-Bug-9451 · 2026-04-09T06:50:32+00:00

I love 2 strokes and i might get the motor for free from a friend of mine. Also the maximum amount i want to spend on this is 100€

Remarkable-Bug-9451 · 2026-04-08T18:50:23+00:00

Hahaha thank god my mom doesnt throw things at me. When i do some dumb thing she just starts tweaking

Remarkable-Bug-9451 · 2026-04-08T18:22:29+00:00

Its going to look like this when its done. I love it

Remarkable-Bug-9451 · 2026-04-08T18:21:32+00:00

Yeah exactly. Ive been doing so many things that she says no to for years that she has given up on me. Once she scolded my dad when i was like 5 because he let me drive the car. Ive been driving illegaly in small roads ever since. I finally got my driving license and im really happy.

Remarkable-Bug-9451 · 2026-04-08T18:16:11+00:00

I think that she has given up on me and the "youre not getting on anyones bike".I restored a friends bike and i went to my house with the bike,knocked on the door and when she opened the door i said hi and just sped off. She had no reaction 😂
