alright guys so i was riding the other night in the snow on the slick roads.. i was gettin it in 4th gear wide open and let it run itself down in the rpms but not to low, went to grab 3rd for a stop sign and it shut off and wouldnt start back up.. it was locked up for about a minute after it just shut off but the kick broke free. the wheels never locked thankfully, just the kick start. anyway i got towed home and let it sit in the yard, came home today and it started right up but has a gnarly knock in my bottom end... i put some more oil in it and it helped but it was no cigar.. the plug looked a little rich but also had like a watery substance on it, kinda hard to tell.. it rode alright for the little i did today but im a little concerned about what the noise is and if anyone had good insight to what i should look for when i tear into it. thanks guys you are a good help
