Had huge amounts of blow by...hmmmm.....did a compression check (pics attached)....no problems, compression is great!!!
Blowing oil and fowling spark plugs...WTF?? couldn't really adjust carb, kept backfiring...so....did a leak down test....honestly, if you can, once in a while do a leak down test...it tells you a lot.....
found out, my REAR CYLINDER EXHAUST valve was sticking....leak down failed, at TDC, blowing AIR out of exhaust??? WTF???? But, it ended up explaining a lot.......backfiring, carb not running right, running rich, killing sparks....so, I am going to pull my rear head and see what's up with the exhaust valve on the rear...I'm guessing it's carbon-ATED too much??? hahahah
I can still ride it like a bat out of hell....and boy does it get HOT.....LOL....power out the ASS....but....hey, need to fix it....
Attached pic of the front cylinder leak down which is perfect...but, site won't let me upload videos of my compression or leak down checks for both cylinders...oh well....just know, that on the rear leak down test, it would not go over 15 psi while blowing air out my exhaust at TDC.....
Cheers.....
