One of the largest issues that you run into is that nobody has a lot of experience trying to make these bikes go faster. I have dealt with all the top guys in America and they may have done 1 or 2.
The good news here is that APE and their workers have great relationships with the racers on the west coast and they can use this. Just today I talked to Jeff @
APEmike and he gave me the below tips on the motor in roadracing conditions:
1) the oiling system sux. Everyone recommended doing the oil pressure mod.
2) the crank and rods are weak links. Many times this leads to premature bearing wear from flexing.
The point is: As we try for more HP, we expose more weak links in the chain. Now I'm not sure if I got the bike built on a Friday 10 min before quitting time, after a Thursday night drinking binge, but I have seen many durability issues as I have pushed the HP limits of the stock components.
