yea, defiantly requires a lot of hard work and talent, I still remember my days when i did side jobs wrenching for Attack Performance, still remember the 24 hr at Willow Springs endurance races, those were hard on everyone. I still remember rebuilding a bike for a very fast buddy of mine Paul Mumford (R.I.P) got the call at 4 PM i want to race, motor just got finished at Attack, and they have a new frame for us, I started at 7 pm work till 3 am loaded it on the trailer I slept the 2.5 hrs to Willow Springs, at about 6 am worked out the last bugs and then got it running, got a few heat cycles on the bike stand before it was on the track. then tuning the new carbs and suspension. if i remember correctly we finished 12 out of 28 and we were the first privateer beating out a few of the factory guys. man i miss those days.
