So my girl friends dad just gave me a yamaha pw 80. Not sure what year, the serial number is 21W-006227. So what year is it? Also it has little power but will go in 1st, as soon as you shift into 2nd it has no power. Any ideas?
SOURCE: i have a yamaha pw 80 that starts but stays revd
Check the screw on the side of the carb in the middle, just under the slide and screw it counter clockwise.If this has no effect I suggest you check the cable adjusters to make sure you have free play on the cable.
please leave fair comment if I have helped you
thanks
SOURCE: How do I tune up
Remove and thoroughly clean the exhaust and muffler of soot/carbon buildup, test/replace the spark plug, test/replace the coil/wire assembly, and ensure that the chain is at it's proper tension.
A full bike workup includes aligning the rear wheel, checking strut/shock damping pressure.
While the plug is out, if you have a compression test unit, or can get one, test the engine's compression. It helps over time to develop a chart of compression readings from each tuneup, when it comes time to properly diagnose engine problems.
SOURCE: My yamaha pw 80 kickstart
Below is a diagram of the inner part of the kick starter. The spring clip shown is the problem. If it gets weak, it doesn't hold the ratchet gear as snugly as is needed. It is best to install a new clip but often you can just squeeze the clip closed a bit for a better hold to the gear.
Please rate my answer. Thanks!

SOURCE: My yamaha pw 80 won't kickstart and can you tell
I'm assuming you mean gas comes out the spark plug hole with the plug removed??? You probably have a gummed up carburator, due to old gas or dirt. Make sure your air filter is clean first, and then get your carburator thoroughly cleaned. If your float is sticking, or the float needle is dirty or worn out, it will keep dumping fuel to the engine.
SOURCE: one end of little black hose came off my sons
Just guessing because I can't see what hose your talking about but if gas is coming out the hose when you turn it on I suggest looking at the carburator and I suspect the hose came off the inlet to the carburator. Thats the only place gas goes after leaving the tank, if it is coming out the overflow for the carb then your float is stuck. Some bikes have an overflow hose for this reason and it does not connect to anything just hangs down to let gas drain from the carb.
