Yes certainly I will keep you informed. It has been a bit of a slow process, finding time, work has been very busy and after hours is being soaked up with the Kawasaki Bighorn. It's always had a problem with leaning out when trail ridden??? Why, and yet a five lap VMX no problem? With ethanol there is a certain amount of extra fuel needed as the engine gets hotter but this is way leaner. I fitted a external temperature gauge to a head stud and ran it up in the workshop for about fifteen minutes to check the readings are the same ( as the computer ), suddenly lean condition appears and low voltage warning on the computer. The alternator it seems has enough grunt to keep the battery charged above five to six thousand but below that the charge is negative, it's only a small battery. I'm getting the stator rewound to be more efficient at lower rpm's. I know just keep it pinned
BTW Lozza, part of the reason the bighorn kicks sideways is the rear wheel is moving 10mm side to side!! I need to replace the bronze swing arm bush with an aluminium bronze bush, much harder.
The fuel pump is the problem as it draws just over four amps all the time, even when the engine is idleing. It is a standard car HP pump so delivers way more flow than needed. I'll need to find something a little smaller for the YZ project. Fourstroke MX bike pumps look very similar to mine, big and heavy. That's just a waste of energy!! The YZ project flywheel and stator are late model rare earth magnet type, this will help, smaller too.
