Re: smoking pipes
If there is a hole drilled in the air box you better cover it over with duct tape soonest. The air flow is a reverse flow compared to almost everything else out there. You are getting unfiltered air into the engine. Pull out the air filter and you will understand. It gets dirty from the inside first because the air enters from the center and flows out through the filter material.

How large is the hole? Sounds like some previous owner tried to pull a Honda Civic intake mod on the GZ250 and made a mistake. |

Re: smoking pipes
Well, whatever it is, it shouldn't be there, so you might as well fill it.

Re: smoking pipes
Hey so I'm back again and have a new problem. I finally got the bike running well, no smoke, no oil leaks while its on. I finally put my first seafoam free tank of gas in it and it's been cruising better at low speeds. My only problem now is when I go to shut it off, it lets off a big puff of white smoke from the engine. Sometimes it goes kind of ghost mode, I turn it off and it turns over 2 more times before cutting off. It looks as though maybe the carburetor might be loose? But it still backfires really loud on shut off. What might cause one big puff of smoke after shutoff?

Re: smoking pipes
That's called dieseling and it's caused by the engine being way too lean. The chamber is so hot that the excess explosive bits get heated enough to blow up again.
It's an issue that you really need to look into. If you have a carb that isn't fully sealed to the manifold, then that is most likely your problem. Too much air would be getting in causing the whole thing to run way too hot. |

Re: smoking pipes
So it was definitely the carburator. It was just loose. I straightened it back in there and it shuts off easily now. Thanks for the help.
