My keeway hurricane 50cc suddenly started smoking terribly bad

You have a bad ignition module.

Hello
We do not hany repair manuals for any type of motorcycle or scooter, they are copyrighted and not free to obtain for download, sorry. To obtain a service manual for the scooter you will need to contact the parts dept. of any dealership that sells these. I am not aware of any dealers in this state and have never seen this brand in the USA (We are based in San Mateo, Calif). Good Luck

Check to see if your silencer need a decoke .unburnt oil blocks up the silencer and reduces power output .

This is either worn valve stem seals or worn out oil rings. Have someone follow you if the car smokes more as you release the throttle on deceleration it is most likely valve stem seal if it smokes more on acceleration it is worn oil piston rings. If the smoke is white you have a blown head gasket blue smoke means burning oil, black smoke means too rich (to much gas reaching motor)

The sputtering was a bit of water in the bad gas you got and the smoke was probably from a bit of diesel fuel that was put into a gasoline storage tank in error. The temp guage going bad is just one of those things that happen from time to time, probably just a bad sensor. The idle speed change is a bit quirky but easy to adjust. Stick a fresh set of plugs in the bike and the starting problem should clear up.

A “very helpful” rating for this answer? Thanks!

if you look down from the handle bars to where your feet go you will see a little rectangle on the plastic, if you pop this off the VIN is underneath

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

well i had the same problem with my old ttr 90 it smoked realy bad so i took off the top end an looked at the piston rings an they were fried so i bought a new piston rebuild kit an put it in an changed the oil an it ran like a champ an didnt smoke so thats what i think ur problem is
