Ok my 98 that came in the box is still running good not great but its hitting all the gears and doesnt bog or anything but I think the crank seal is f#$ked. No matter how long I ride it, it smokes like crazy. As a joke that it even runs and I put it all together with out a book of any king. My father rides it around his yard and says he foggin for skeeters....lol You would have to be there. It uses about half a quart in 5-6 hours just tooling around keeping up with the pack. I do have it running rich just cause I know nothing about this thing and trying to keep it running/riding a few months before I rip it down and do it right. I just wanted to see if I could go from parts in a box to on the trail in a week with out a book or ever seeing one in person. Grew up with wheelers though just not a tiny blaster. Matter a fact not many 2 strokes period..... So my question is : How long will this thing last doing it this way ?:-/
