Great information here, guys. Talk about appropriate timing.... I just did an oil change on my bike tonight and HOLY **** I WAS CONCERNED.
The story goes: I was going out for a ride last Sunday and I decided to check my engine oil after my last ride. I had just changed it the ride before with Yamalube 10W-50 and added the .95Q w/o the Oil Filter replacement. Previous oil change was good, full, had some fuel in it (smelled of it), but wasn't anything to be concerned about. Rode the next day on a cold blistery semi-deep day and then came home. So Sunday rolls around and I go to check my oil before leaving.... none on the dipstick. I ended up adding 3/4 of a Quart before the dipstick finally had a reading and then what I ended up with on the stick looked foamy and white. Heated up the motor, checked again, foam was gone with addition of new oil, rode that day checking my oil every hour or so. The level indicated the oil was fine and the white went away and became dark like a normal oil.
During the Sunday I rode the bike I was banging through some deep heavy snow almost all day.... full wide open throttle through the tree action.... you know, one of the good days. I did have problems with my vent lines clogging up. I'd be pulling a sweet line up through some trees and then I'd let off the throttle to turn downhill and the bike would just go straight to dead.... I couldn't blip the throttle to bring it back either. Check oil level - good - beat vent lines clean - head back out. This happened about 5-6 times near the end of the day when the snow was really deep. Checked oil level again, good and no white stuff.
Got a call to go ride tomorrow and I decided to do a fresh oil change tonight and keep another good eye on the level. Warmed the bike up, cracked open the drain plug on the bike and only about 1/8 of a Quart ended up in the pan. I immediately freaked out and decided to check my oil level.... guess what, it says my bike is full. Pull the oil filler cap and there is a white thick goo all over it. Pulled the airbox cover and there is a small pool of white thick goo at the bottom. Pulled the radiator cap and the level is plumb full and the overflow container still has a small amount in it like normal - no coolant missing.
What the hell is going on here? My level reads full when it's not. I keep losing 7/8 of my engine oil per ride (2 rides this has happened on). Vent tubes were probably clogged on both days but only on the 2nd day did I notice any performance woes with the bike dying. I figured on the first day that I just didn't let the bike come up to temp and the piston rings didn't seal therefore causing some serious blow-by. On Sunday I made sure to warm up the bike and take it easy right out of the gate.... still, lost a ton of oil. I'm seriously freaking because now I think I burnt up my piston rings and I need a full top end rebuild. If I'm not losing coolant then where is the water coming from? Is it a ton of fuel in the oil causing the foaming and goo buildup?
What do you all think is going on? I could really use some help here before I go break the bank and my local dealer.
