Is that normal??(video)

[adriano.ro]

I'm little bit concerned about the smoke after the dropping rpm. Maybe is normal but I want to know from you if that smoke can be from bad sealing or something else. Bike was warm up about 70-80%. The smoke isn't quite blue,only in high rpm .

It is not normal in my opinion, how does the smoke smells like! When it smells different than normal the possibility is very high that you burn coolant.

I forgot to mention something,the oil from vent tube,left side isn't black,is brown.

I don't have pressure in radiators. Bike start fine ,idle very good.

Mine was doing that. I was leaking at the collar that joins the silencer and pipe. I fixed this leak and it seamed to go away? I can check this weekend and verify its not doing it anymore.

Interesting. After your checking please update the results here.

I had a bike once that was burning crankcase oil because the crank seals were worn. I'm not saying that your bike is burning crank oil. I'm just trying to help out with possible causes. My bike smoked ten times worse than yours so if it is the seals maybe they are just starting to wear.

Mine is doing it again as well. I noticed the exhaust collar is leaking again a little spooge again. I didn't get to ride it long at all though.

 

[adriano.ro]

Can you post some pictures?

 

[Scruse24]

Yeah. I'm out right now. I was going to fiddle with it after while. I did a little research and it could be crank seals. Not sure why mine would wear at around 30 hours.


Edit:
I'm going to drain my fluid and see how much I get out. That should help diagnose if it's a right hand side crank seal.

 

[adriano.ro]

Can I take off the right side seal ,without taking off the clutch ?

How old is the gas ? Did it have any additives (smells rather strange at the gas pump) ?

If i were you i would empty the gas tank as a first measure. Put new gas in and take it for a quick spin while watching the oil and coolant level.

 

[adriano.ro]

I use fresh gas every time,no strange smell, anyway I just bought the seals. I have to run about 4-5 hours and after that I will change the transmission oil,and then I can se if the oil is gone somewhere.

 

[poelinca]

Let us know what you find, hope it's nothing major.

 

[Scruse24]

My oil measured Out fine. Im riding this weekend. So I'll post if I find anything.

Update: with new seals ,bike run much bette,no more rich sensation and pulls much cleaner. And no more lean felling. Consumption is good too. The power is spread more lenear and sound of engine is more uniform. Tomorrow I want to see spark plug color,I'm so curious now I can really start to jetting the bike.
