I need help bad...... I f'd something up
Alright so i have a 04 and i changed my oil last sat. to go ride sun "yamahlube 10w40or30 cant remember what the shop gave me with a new stainless steel filter" everything went great bike performed well no wrecks no issues at all. I was running race fuel for the first time in it (not a high compression motor fyi) well tuesday someone told me to flush the race fuel out bc it would eat the o-rings up if i didnt. So lastnight after work i go to drain my tank and run pump gas back through so i started it up and let it idle to warm up for about 5 min. and i as i jump on it and gave it some throttle to ride for a min. oil starts to gush out of this port just above where the header connects to the head( it looks like a plug should go there but there is not one) and smoke goes every im assuming from oil hitting the header i immediately shut the quad down it wasnt making any noises and it didn't seize up on me as far as i could tell so rolled it back in to my shop and here i am now . i have no idea what this port is for or what i have done wrong im kinda new to this Quad and could really use the help any advice on what went wrong and what i should do next to fix the issue would be greatly appreciated. it wont let me upload the pics but ill keep trying....

Very common on the 04's. They corrected this on all the 05 and up models. You need to get a metal plug to replace the one that is in there now. Do not run it as it is, it will just leak, and I have seen the oil leak onto the header pipe, and cause fires. I got mine off thumper talk but I am sure our site sponsors still have access to them.
