Blasty smoking...possible concern??

[ProjectBlasturd]

Ok I need the help of my forum family here. So my blasty ran like a charm prior tome doing anything to it. Just the lightest tint of blue smoke like any two stroke should, no stalling or hesitation issues, no high idle or rev, nothing like that. I decided to do the oil injection block off, and I flipped the reeds around because one of them needed flipped. Put new fluid in the clutch cover sealed everything up with yamalube where it was needed, put everything back together, and now I'm running into this concern. It's it's in a heated garage so I know the cold isn't an issue, but I started it up the other day and seen some grayish colored smoke coming from the exhaust. I only let it run for about 15 seconds or so so I don't know if it will go away or not, but I've seen people say that that is usually an indicator of a crankcase seal. It didn't smoke like this prior to doing the oil injection block off or flipping the Reeds and now I'm running a 32:1 fuel ratio. I didn' perform a leak down test because I know for a fact I sealed up everything pretty damn good being that I've used yamabond in the past on a lot of my four wheelers and know the proper way to use it to seal things up correctly. Do you guys think that smoke could be caused by condensation in the expansion chamber? The only leak that I am fully aware of at this current moment is the leak I have coming from the shifter shaft seal which isn't a crazy leak it's only a drip here and there. Funny thing is I know I don't have any air leaks because from sitting in the garage apart this whole time and then starting it up it started over on the first kick. And yes I did drain all the fuel out of the tank and out of the bowl of the carburetor after doing the injection block off when I put in new premix

Here' a link to the video I took of it smoking. Let me know what you guys think

it is going to smoke out of exhaust more
going from oil injection to 32:1 pre-mix.
i would not worry about it as long as it smells like
the 2 stroke oil you put in it.

Yeah but are you seeing the color of the smoke in the video?? That' not blue smoke lol

 

[speedyslyder]

well if it is burning tranny oil it will be white and smell like sh.it!
if it is the castor 927 maxima that you said you pre-mixed it will smell goooood:
and what i said is true the oil injection pump will not smoke as much as a
constant 32:1 premix will
especially on start up or at low rpm's

I didn' get the maxima. I ended up going with the yamalube 2R. The tranny has maxima in it. I just don't see where the white/grayish smoke is coming from all of a sudden. Like I said, it didn' do it before the block off and I didn' pull the cases apart so I know I don' have a leak there. The only thing I pulled off was the carb and intake to flip the reeds and I used yamabond on both sides of the paper gasket and on the intake to reed cage and it' all sealed up real good. Also uses yamabond on the clutch cover although I wonder if I could'e reused my clutch cover gasket maybe with a thin bead of yamabond cause it wasn' messed up and still looked pretty damn good. As I said, only leak I have is from where the shift shaft goes into the case

Also, as stated, it's been sitting in my garage for about 2 weeks or so now without being started.

never tried the yamalube 2r just the 2s
seriosly either it is 2 stroke oil or tranny oil
smell it out lol

Lol if it's tranny oil then I'm baffled cause that means from the time I took it apart till the time I put it back together my crank seal mysteriously blew out on its own without being touched hell I won't even lie I've never smelled burning tranny fluid on a bike so that would be something I'm unaware of what it smells like

The stock oil ratio is around 20:1, and should smoke more than a premix of 32:1....

everyone can search how a autolube oil pump works.
also anyone is welcome to decipher this.

Let it run to get the pipe hot and see if it clears up . I use Yamalube 2r and it smokes a little more after it sits for a few weeks but clears out once she gets hot . I warm mine up to 200 before it moves . Sounds like your idle is hanging up a bit . Adjust your carb. and check for air leaks around the reed cage . Did you block off the oil injection nipple on the carb .

 

[82cutty]

Like Speedy said it will smell like crap if you're burning trans. oil . 2r smells pretty good with 93

I did block off the oil injection. And I don't see my engine brining tranny fluid cause the longest I've let it even let it run for was about 20-30 seconds. There' no way tranny fluid could habe even gotten into the case if it' been sitting and only ran parked for 20-30 seconds. Prior to that 20-30 second idle time it was sitting for a week almost two weeks. So I'm wondering if it's smoking because I switched to a 32:1 premix and because it' been sitting.

Also by adjust the carb to clear up hung throttle are you talking about adjusting the idle screw?

 

[82cutty]

Yeah start with your air screw out 1.5 turns then bring the engine up to operating temp . Then adjust the airscrew to where it idles the highest then re-adjust the idle to where it will rev clean and go back to idle without hanging up

Ok I gotcha. But yeah, if you just read my precious response, I'm ruling out crank seals. Also, even though I didn' do a leak test, in positive there is no air leaks. I sealed everything up and I don't have a high or erratic idle and it idles nice and smooth

 

[82cutty]

You might have a small air leak also if after adjusting the carb. doesn't take care of it . It should rev clean and go back down to idle relatively fast .

 

[82cutty]

Just seams like it hanging up a bit in the video
