So i growned some worries about what you mentioned...how do i see if there's any? i have to empty the engine oil in a pan and see if there's any gas?
And change oil and filter... good for me that i bought two of them when i got the supplies for the oil change...
Do i have to do it asap?
Thanks again for any hints and suggestions...
All gas engines have some gas in the crankcase. More than 10% is an issue. Always give the oil level window a glance after a long period between runs (overnight) That's another reason on the kickstand, bottom of the window method works, all you need is a bit of light and to stoop a bit. Clear window ok, black window bad.
Some say take the cork out and give the case a wiff. Level method is more definite.
As far as the filter goes... a little gas in the oil won't hurt the filter. The only advantage changing the filter is additional gas contaminated oil is removed. So open it up, get the oil outta there, and put it back in.
So, i've checked the window with the bike on the side stand and it's pretty clear... i've also smelled the oil from the filling plug as suggested from Steve H and it doesn't stink of gas, so i think i' m in the clear... but just for sake tomorrow i will drain, change the filter and fill it up again, maybe with new oil...
And just for the record, i' ve been back to the original spark plug, the NGK DPR8E-A, but from what i read from the owners manual the NGK DPR7E-A is a substitute in case quote "if standard plug's insulator is dark, replace with this plug".
Even with the DPR7E-A fouling was accumulating on the insulator and on the arch (before all this float "job")
I put back the original spark plug so i can narrow down cause and effects of the various works done to the carb.
