JH600 stalling

[euphonius]

I know people are going on the 'bike is too lean tangent' which is highly logical and plausible. But shouldn't EFI systems be able to adjust for it? Also shouldn't a Bosch EFI system work as well if not better than the industry standard, and shouldn't it be easy to achieve with a 600 single, being a fairly simple and well known design?

This is only a theory, but maybe this could be an electronics issue and the spark is too weak? We all know Chinese shops don't adequately trickle charge new batteries overnight, we know that a company like Jialing might have mediocre wiring and that the ignition coil and leads might also be causing the problem. Just a theory to eliminate.

Dear Z,

Your reasoning is sound. There could also be significant quality control variance between individual bikes, given that they are essentially hand made in monthly batches only after customer orders have arrived. This would explain the wide variation in stalling between individual JH600s.

I do have stalls, though not nearly as bad as others (knock wood), as I approach 10k km on the bike, my engine and EFI are completely original save for an NGK plug and the aftermarket Laser can.

You'll recall that when you and I rode through Qufu in summer 2010, under incessant torrential rains, my JH600 was fearless, even in deep floodwaters that sometimes reached my knees. Did Jialing buy a better grade of copper wire when they assembled my bike, and Barry's?

I do like the way this is putting Jialing on the spot. Making motorcycles is an adult activity, and requires a certain minimal level of corporate responsibility.

cheers!
