Is it recommended to keep the charging harness in tact after swapping to the new EBR rotor, or is it okay to remove at that point? Any opinions on this? Any official word from EBR at all? | ||

That's a really good question. Unfortunately, we don't yet have any firm temperature data to answer that question, so we're forced to base our decisions on theories that sound good but haven't been confirmed or refuted yet. If the oiling rotor sprays enough oil to lower the temperature of the stator to oil temps, then you'd think that you could remove the harness and let the charging system stay in 3 phase operation without risk of burning it up. But then there's that problem where oil flow inside of the motor is dependent on engine RPM. At low RPM you have less oil flowing, so you don't really benefit from the oiling rotor as much as you do at high RPM. This means that oil flow goes down at the worst possible time -- when the oil flow goes down, air flow is also going down, and the bike is starting to retain heat. I think of the harness/oiling system as a 2-way safeguard: By itself, the harness update only protects you at low/intermediate RPM. It provides no help for you at medium to high RPM. By itself, the oiling rotor only protects you when oil is flowing at adequate pressure. That's at higher RPM. It doesn't do much for you at low/intermediate RPM. One way to look at it is that the harness and the oiling rotor compliment one another, so that one works at high RPM and the other works at low RPM. For the time being it seems like the safest thing to do is to leave the harness connected -- until we can confirm that the oiling rotor adequately cools the stator over the entire RPM range. Just my $0.02. |
