I have been a proud owner of my Qlink Xf200 for just over 7 months, I purchased it with 400 miles on the clock, and the original oil still in it from the first owner. The bike is a 2008, I have put just under 3600 miles on it since Late September 2009.

Here it is in original trim:


After doing oil changes every 500 miles about (some after 200 miles due to some dirt riding) and valve checks twice since I got it (First was waaayyyy off, second was still good after I fixed it the first time) it was running great.

I have done some simple mods:
Opened up the Exhaust by removing the Catalytic converter with a long drill bit(Free)
16tooth front sprocket from SPROCKET SPECIALIST(15$)
125 main Jet, 35 Pilot (10$)
Raised Needle (Free)
Protaper bar adapters(30$)
Sunline Wide Bars(25$)
17inch set of Shinko 244's for dirt/dual sport(70$)
Stock tires for Street duty(Free)

Bike runs awesome until today...

Riding a 1 mile journey to class today and 100 yards from class I have a 5mph right hand turn. Slow down, Downshift, Lean in, ALMOST LOWSIDE!!!! I look back and there is a 200 foot long trail of oil on the ground (and subsequently my back tire!!)

I parked the bike, went to class, came out and started inspecting. there is oil all over the motor from the valve adjustment caps down. Here is a Picture I took an hour later with the tank off:


So I start inspecting starting with the easiest parts:
Too much oil? NOPE
Oil overflow? NOPE, that wouldn't get up this high on the motor
Valve caps tight? YES, no oil is coming out of them, its all below them
Valve cover assembly tight? YES

So I turn the bike on and BAM, RIGHT IN MY FACE. In the picture above there is a SILVER ACORN nut, not even finger tight, with clean oil PUMPING out. I check all the bolts/nuts above the cylinder, replace the oil filter, refill the bike with oil (which took almost 1.3quarts to fill up to the middle of the sight glass with the bike level, usually takes 1 quart).

I restart the bike, let it warm up, while constantly checking for leaks. NO leaks, no issues, steady idle. I get ready to go ride to my later class. It rides fine to class and the 5 mile detour I took I had ZERO issues.

Come out of class, Start it up, ride a quarter mile and smell lots of burning oil at a stop sign. Look down and there is a puddle of fresh oil under the bike.

WHAT THE HELL!!!

I get my truck, load up, and parked it in the garage. Same issue as this morning, oil PUMPING out of the acorn nut.

What could my issue be?
Symptoms currently:
burning oil--NO
Airbox is clean
Oil filter is new after the first time today

Is my problem a blown seal somewhere?

Here are some more pictures of the aftermath:

THE SAVE (if you look closely enough you can see the knobs sliding on the pavement)


THATS SOOO MUCH OIL ON THE GROUND!!!!
