I forgot, 3/0 244 SHINKO tires, 110 bucks?. I am also running a 13 tooth in front. 20 bucks?. Drill a couple holes to raise front fender for clearance of tires in front. I over gapped the top two rings by accident, but I recommend doing so as I do believe it will prevent it from failing. It smoked a little on startup,then quit after it warmed up. After 1400 miles on bbk, I pulled out on Hwy 91,and a car comes flying around corner and I am wide open on throttle and when I hit second gear the rear tire spun and It actually slid and I had to recover from overpower. I could not believe myself.I keep forgetting,but I will check compression. 13 tooth in front is a must.Try and blow it up!
