SOURCE: 2 stroke engine smokes. how do you adjust the fuel/oil mixture?

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

SOURCE: what oil should i have in yz 125 2 stroke

The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.

SOURCE: I have a 150cc jonway scooter. When I open it up

I found that if I run 87 octane gasoline the engine accelerates up to full speed without the skipping and bogging down at any point it is running. It is worth trying. also try putting some "Sta-bil" fuel stabilizer in the gasoline - it has the ability to keep the carbureator cleaner. Not just during the time you are storing it, but rather all the time.

SOURCE: how do i derestrict my lifan s-ray 50cc 4-stroke

Unless you find a small "restricting washer" between the head and the exhaust pipe...Then usually there is no easy means. In the past these "washers" were put in place to reduce performance, the idea was as the riders skills improve the washer can be removed. It also was a way for parents to keep their children from zooming flat out everywhere.

Oil in engine scooter


to start with is it a 4 stroke or 2 stroke. If it is a 2 stroke the oil goes in with the petrol. If a 4 stroke look for a removable plug in the crankcase

Does a yiben 125 4 stroke ....does it use 4 stroke oil ? and where does it go?


Yes, this scooter uses 4 stroke oil (also know as plain old motor oil)
The manufacturer suggests Hi-Rev 740 synthetic 10W40 motor oil.
You can order it here:

http://www.chinesemotorcycledealers.co.uk/fluids.php

You can use any synthetic 10W40 oil. Not sure of the prices in the UK, but I assume it will be cheaper getting it elsewhere, rather than from the dealer/manufacturer.
Hope this helps!
P.S: You can order a manual for this bike here:

http://www.chinesemotorcycledealers.co.uk/haynes_manuals.php

Will tell you exactly where/how much oil to put in.
I couldn't seem to find that info anywhere.

My scooter wont start can u help


It is definitely frustrating when you can't get your scooter or moped started. The first thing you'll need to do is to narrow down the problem. In order for your gas scooter to start, it really only needs 3 things:

1.
Your scooter needs to spark at the correct time.
2.
Your engine needs the proper fuel/air mixture and exhaust flow.
3.
You need sufficient engine compression.

Top 9 Reasons Why Your Scooter Won't Start:

1.
Try depressing the brake handle when starting.
2. The battery has not been charged.
3. The battery is hooked up wrong. This is often the reason for blown fuses.
4. There isn't enough gas or two-stroke oil in the scooter.
5. There is a gas flow problem, especially on the Euro Scooter or Yamaha models.
6. The spark plug wire is not connected.
7. A low battery or bad relay can cause the scooter to only start by using the kick starter.
8. There is no spark to the spark plug. The coil is bad and needs to be replaced.
9. Turn the key to the "on" position.

What is the ratios of oil to gas?


32 to 1 equals 4 ounces two stroke engine oil per one gallon of gas. Be sure to use two stroke engine oil and not motor oil.10w40 motor oil is for the gearbox.
