Topic: cleaned carbs on, a little smokey?

[cudjo]

does the smoke last a while? does it only come out at certain RPM's? have you tuned the carbs yet? from your avatar, it looks like you have an F2. if that's the case you may have leaky valve guides like i think i do. but mine isn't just puffing out smoke like what i am gathering from your description.

 I think that I have a F3, (the 78 is the F3 right)...I have a 78.
I have not tuned the carbs yet.
as for the smoke it comes on after the bike has been running for a min or 2, just idleing, dont have the bike on the road yet.

I think that i might be going with TT's diagnosis, I just felt the inside of the pipes and there is surely some moisture mixed in there with that soot.

what is the valve guide, and how would I know if they were leaky?

[J.Webster Designs]

does the smoke linger? for instance... when it comes out of the pipe, does it act like steam and disipate like the steam coming out of your tailpipe on a cold morning? or does it act like actual smoke and act "heavy" or stick around? for instance, when its inside a garage or a closed space, will the smoke linger inside the garage?

the valve guides are inside the motor and you will tell if they are leaky by burning oil giving you a light blue smoke. does the smoke ever go away? or if you leave it running will it ever stop?

I wouldnt say that it lingers, and i wouldnt call it light blue....

and ift its water like TT says then it wouldnt go away until i had the bike going at highway speeds for 20 min

I have  to say midnight08, your avitar is a bit disturbing..... just a bit....

im saying after the "smoke" exits the pipe... i think you are going to have to get more decriptive with the smoke. or take it to a shop to have someone know what they are looking for identify the smoke at least.

the smoke is white, it is conststant once it starts, i dissipates fairly quickly, doenst seem to linger much, not for more than a 5, 10, sec.

I will probly be taking it to a shop.
dont have any money for service right now, so I am trying to do as much as I can on my own.
there is also the slightest rattle/ ticking when the motor is running, that i want some one to check out..... may be nothing, but i dont know, and I wouldnt be able to describe it any better to ask anyone on the forum.

You said it was smoking.
I gave guidelines about smoke color.

The F3 is notorious for wearing out valve guides rapidly.  This would give smoke with a blueish tinge and it would smell like burnt oil.
When guides are worn, it leaks oil onto the back of the valves.  The intake valve guides would pour oil into the chamber, and the spark plug could have oil deposits or be wet with oil.  If the exhaust V guides are worn, it dumps oil in the exhaust header. This will leave oily deposits in the exhaust that won't dry out.  Mixed with soot its almost like tar.  If the soot deposits are wet with condensation, they will dry out and leave fluffy black soot.

We have to go on your reported conditions and observations.

How many miles on your F3?

the bike has 10k on it.
the smoke is white
the smoke dose not smell like oil.
in thinking about it, the bike has probly been through several cycles not staying a t full temp.
the PO who was in WI took the bike for a few spins around the block after getting it out of storage. but this was a month ago, and the temps in WI would have  in the 50s mayb.
then I did it a few times, not riding but on for a few mins with some reving then off....

your first call, for the water being the culprit, seems to make the most sense... but it looks like I will have to wait till i get the bike on the road, or to a mechanic to be sure.

thanks for sticking with me on this i know that my newb questions can be tireless.

How long have you run the bike?  When I got my 76F running I ran it several times for short periods of time (1 or 2 minutes) and just in the garage as the brakes were not hooked up yet.  Then one time I let it run much longer and I had some white smoke.  There is a small hole in the inside bottom of my muffler and it actually spat out water and made a wet spot on the tire.  It is spring here with much variation in temps and I chocked this up to condensation.  It has not happened since and now the bike is on the road.  If you can't get it out on the road put a fan on it and let it run and get up to temp.

I'll try that out... thx

put the pipes back on, let it run for a bit.
smoke subsided after about 15 min. and came back a little after i reved it a few times. i suppose the revving got another part of the pipe hot.

Ill keep an i on it. still have to take the pipes back off and put new gaskets on. there semed to be smoke coming off the engine... but i coudnt tell cause i know there is smoke coming out of the #2 connection to the pipes
