SO i did my leakdown test everything was air tight... i went riding yesterday with a couple of my buddies the bike ran great everything seems to be better with the clean carb an the exhaust fixed. however i was wheeling on the blaster and when i popped it up i heard i noise i looked down an i spun front sprocket or somthing 1 tooth is completly broke about the first 1/8 inch is cracked off the tip (guessing the length) about maybe 3 teeth the ends of the teeth are wore down like they dont have that slight hook on the end of them as much. i was about 5 miles from my house give or take a mile i let the bike cool down an set there while me an my buddy rode his 400 ex. i had no way to get it home i have no licence or vehicle to pick it up an we were way back in the woods. so i started the blaster up an took off very slow. it wasnt maken any noises or nothing so i had no choice really but to drive it home. could that have done an seriouse damage... if so what should i look for. On the ride home it ran smooth besides it seem to have a slight bit( very slight) less pick up when i took off. there was no noises from the chain an gear changing was smooth as well i took it easy on the ride home besides running down the one public road we had to go down. please let me know anything i should be looking for.. (sucks the first time i got to ride it since i been waiting on the leakdown test it breaks.)
