there out there u just gotta look like a mofo for that cheap, someone on here buildin a drap bike, found a shee for 800 looks pretty decent, but i'd look more at the 1200 range
pack em every 20 hours, pipe company's say theres a major loss in power, but ive never felt it, but backpressure is def needed so repack them, not hard and not expensive
yea for mx the ideal rear tire is 18 and front is 19 or 20, but if ur just starting goand u still go trail riding i'd say stick with the 20's on te back
i agree with everything nasty said, its not that bad doing it, i just did mine and was worried to hell bout it, then i did it and i realized how easy it is to tear apart a 2 stroke motor
works great for mx'n or trail, great bottom end snap, i think it looks pretty trick to, the price can be a kick in the balls thou, but i think its worth it
