Blowing smoke

[Swinger]

I had my ride out yesterday and after it got hot it smoked real bad. Starts easy, idles nice but when its warmed up, not a bug around for two miles. Im getting ready to tear it down and do all new gaskets and seals and maybe a total rebuild. Was hoping someone could tell me what I got going on, thanks

[Swinger]

Still has stock pipe and was wondering if that may be it. Gets hot and all the old carbon is burning out, just a thought. Anyone!!

[big red in iowa]

what color is the smoke, and what machine is it

[dougspcs]

Most likely thing if it's 4 stroke..

You probably had an oil ring break. This ring 'scrapes' the cylinder wall on the down stroke to remove excessive oil.

Or you didn't watch you oil level and you were revving the piss out of it and fried all the rings!!

Next time you post asking questions provide some detail to your question..

[Swinger]

Sorry, it an 84 tecate and its white smoke and smells like old oil thats why I was thinking maybe its the pipe. Usually has that good 2 stroke smell to it but not anymore. I run golden spectra at 50:1 also

check coolant and trans oil level. If you suspect its the silencer pull it off and see if it still smokes so bad. How did it run otherwise?

[ama009]

Could be blow by. Oil getting past the rings. Maybe. haha. Just kidding. I have no idea.

Seemed like when I got to the top end it didnt want to go anymore. Top speed around 55. No band in 5th. I put in a different water pump impeller because shaft was pitted on old one and reused the seal in it. Seemed like the seal was like new but maybe I damaged that. Im just getting fed up with working on it more than riding it. Wanna do one last rebuild and be done. I will try the silencer off today and see what happens.

What colour is your plug??..white and clean = coolant in cylinder, black &sooty/oily = oil in cylinder. What fluid level isn't where is should be??

Honestly, sometimes people are to quick to run to the forum and ask questions when their machines break. It is perfectly within their ability to gather some simple data that may direct their questions better and get better answers.

Get back out to your trike and do this 1st.

Then come back to your computer give us all the information you have and ask questions!! It will stop everyone shooting into the air searching for the answer to your problem.

Help us to help you!!

Ok, thanks. I just got an complete gasket and seal kit and planned on that being my winter project, again so maybe that will do it. I downloaded a manual and got one off of ebay on a cd also to check for specs.

[Swinger]

I will get at it today for sure and am sorry for asking before I checked a few things, wasnt realy sure what to look for. I will be back in a few hrs to give some info. Thanks again

Sounds like you are sucking trans oil through your crank seals. I don't know of anything else that could duplicate the smoke and the smell of oil.

[Swinger]

133778Ive been thinking that but when I had it apart last time(3yrs ago) I put new seals and bearings in it. But that has been on my mind because it has smoked a little but getting real bad latley. I bet I only have 10 hrs at most on it since the last tear down. I just checked and my oil is milky and plug is tan color. Plug was really loose when I just checked, actually almost 3 more turns and would have come out, Im suprized it still ran like that.

[El Camexican]

Wow, ok one at a time
Milky oil = water
White smoke = coolant, or motor/trans oil
Smells like oil = motor/trans oil or 2 stroke oil (you know the difference, which is it?)
Loose plug = you can tighten it up, say 9 ft. #, or change it for one with a new washer (recommended, but likley not needed)
10 hours since rebuild = means nothing. You could hav edamaged the seals(s) when you put it together.

If that smoke smells like burnt motor oil and the oil in your trans is creamy you need to tear your baby down

[Swinger]

Now if my oil is milky then I either have a bad water pump seal or what else could it be and how much damage could this have caused.

[Swinger]

It smells like motor oil. I planned on tearing her down asap and got all the new seals and gaskets but now am wondering if this could have caused damage to my motor. Ill look at the piston when I get it apart and if I have to go that route Im gonna have to I guess

[El Camexican]

Now if my oil is milky then I either have a bad water pump seal or what else could it be and how much damage could this have caused.

The only other thing it could be is if you sunk the trike or sprayed water into the cases through a vent line (or someone put water in instead of oil) As far as damage goes you'll hear all kinds of opinions. For me, if it was not for your leaking crank seals there would be no issues at all, just replace the seal and add fresh oil, whatever trace amounts of water that remain will eventualy evaporate with heat and go out through th event tube, but because some water or anti-freeze did likley get in your crankcase I would hone the cylinder and put it back together unless the rings or piston are damaged. When you have it apart clean all the "cream" out of your crankcase and don't forget to wipe the clutch plates clean with a rag as well. You can blast the crud out of the bearings and gears with WD40. When you put the thing back together make sure you grease all seal lips and shafts before you assemble them. Gently turn the shaft as you insert it, don't just ram it in.This is critical to avoiding your next post titled "WTF is my oil white after I just changed my water-pump shaft seal last week?" And finaly you mentioned something about a pitted impeller shaft. This is bad, especialy if there is surface rust on it. Best to replace it, but if you must use it, clean it up with 2,000 grit paper, but sand it in a circular motion, the same way it turns, not up and down like... well, you know

[Swinger]

I have never even had it in the mud since I have owned it and am very careful when washing it. It has to be the crank seals or the water pump seals, or both. Ive put a good impeller on but probably messed the seal up on it when putting it back together or messed the seals up for the crank when putting that back together. I did the build last time without 3WW and this time it will be done right thanks to the help of good guys on here. I am a semi new member due to the fact of being old school and no computer so this time will be different for sure. Thanks again
