ive blown up two of these really badly. the 3rd one ive got i gapped the ring slightly more than needed just to be safe, so far so good probably about 20-25 miles on the kit and ripping super hard after some warming cycles and putting rides. 4pedal reed, 21phbg, tjt/treats plate 12 grams, hpi 2mm BTC, cranks pipes, rips wicked off low end w/ short gearing 17x45 up to 47mph
