So far I'm pretty happy with the Jialing fuel injection, as long as I don't get a bad batch of petrol and can keep the battery charged enough to drive the fuel circuit. Back in the fall I was all anxious about Jialing's release of a firmware upgrade for the Bosch electronic control module, but the bike is running OK so I've put it out of my mind for now. Maybe I'll ping Jialing this week to see what gives. Jialing apparently does not bootleg the firmware; rather, they pay Bosch for it -- assuming they decide it's in their customers' interest. I've probably said this before, but this was described to me as analogous to computer OS upgrades. Jialing could upgrade the JH600 to the EFI equivalent of Win7, but right now we are still running on XP or 3.1 or "Bob" (anyone remember Bob, back when Microsoft was trying to be "hip"? Yeah, right.) or some other earlier version.

On the other hand, every grease monkey squatting in every "repair shop" in China has some ability to fix a carburetor, which explains why plenty of people prefer that form of fuel application. Needless to say, the toughening of fuel standards here in China and everywhere will have huge implications for fuel systems, and probably give Bosch a couple more decades of profits.
