my last four vin#0166 my bike was bought 4/7/99 the first one at the shop i work at.i have notice on a dyno 200 my bike stock made 150.6hp at 300mi. at 900 mi. it made 151.6,but tq. jumped from 92lbs. to 96lbs.after mods micron pipe,mod airbox,and pc2,it made 162hp and 104lbs tq.but power fell off quickly to 142hp at 10,800.later model busa i've seen with same mods made 168hp to 172hp peak and did not drop but 5-8hp at 10,800.i'm assuming duration had alot to do with it,i've been fighting with this,since my bike had low numbers.hell a stock bike with 10,000mi. made 157hp.iplan on sticking stage1 yosh cams in,i hope this will be a major wake up.any other suggestions will be grateful!
 
At 1200 miles my bike dynoed at 157 hp stock.It was 100 degrees in the dyno room.I now have 4000 miles and will be returning to the dyno soon.Hopefully I'll hit 160 horsepower.I'm planning on the clutch mod,akapovic pipe,bmc filter,yosh stage one cams and a power commander.I'm looking for 170 at the rear wheel.
