I just bought a Keeway Venus that runs good, but smokes alot. I had to clean the carb and get all the water and ice out of the tank to get her going. Now it starts easy, runs smooth topping out at 35mph. It just bugs me that the blue smoke never clears up. Do I need a new set of rings? What other problems may I have? Thanks in advance.
It is a 2 stroke motor with 2500 kilometers on it.

Rings are white smoke and exhaust valve can have a light blue hue on 4Ts . Is it a 4T or 2T ? If its a 2T its good to smoke so you its getting oil .

Hm, by 2T I am assuming you mean 2 stroke? It is a 2 stroke 49cc engine, but I still think the smoke is a little excessive. I can see a blue cloud following me wherever I go. I am thinking it could be rings, unburnt fuel/oil in the muffler, too much oil mixed by injector pump or wrong type of oil? Are all these valid ideas? I like to know before I start ripping it apart. I'm not afraid to take it apart, but I am not a mechanic. So, looking for advice. Thanks

Smoking is a great sign that the pump is working . Cheap or weedeater oil smokes way more than the premium full synthetics like Motul 710 or Bel Ray only smoke when the engine is cold . My pedal mopeds I premixed left a com trail .
My self and others have had soft seizes with a 2T and a BBK . The stock oil pump is not good for high RPMs . I now have a Mikuni brand of oil pump and needed a new throttle cable which is part # 159-26 .
Premix is a safe option but I like the ease of an oil tank . Always top of the oil tank when you get gas .

Everything is stock on this scoot. I have not run it much, maybe I'll just drive it a while and see if it clears up with better quality 2 stroke oil in it. No telling what was used in it till now. There was a 2 inch thick block of ice in the gas tank!

I'd say switch to a synthetic 2T oil. Should reduce smoking. Or ditch the injector altogether and run synthetic premix. If you're using a quality 2T oil smoking should be minimal, but it's possible the oil injector is injecting too much oil.

Thanks for the links, maybe I need to adjust that pump. The scoot runs great otherwise and does not have alot of miles so this make sense to me. I put some good 2 stroke oil in it. |

My wife has same scoot. Smokes a lot sometimes. If you fill oil resavoir (sp) to the top it smokes a ton. Sometimes e in the angle its parked at changes the smoking amount. Gets better as engine warms up. Doesn't seem to effect it. I'm also using $16/at synthetic oil.

I got this thing registered now, if it warms up a little this week I'll ride it to work and see if it smokes all the way or clears up. |

Check the adjustment on the oil pump. Could be adding to much oil. Scooter should smoke somewhat when first started ten calm down when warm. Use synthetic oil only to cut down on use and smoke.

Its better to have extra oil than not enough . So far I had two oil pumps fizzle on me so Id replace with a Mikuni like I did or premix which is the safest bet
