    Only thing that has me scratching my head is that the LEDs won't fire if the DRL lights are on. Not a problem (I just unplugged them), just a curiosity.
    Notwithstanding, I'm quite pleased with how well things turned out for my upgraded LEDheadlights/DualHorn/AuxPower system.
    Now onto that KNM DR3 variator...

    What I've been doing the last week while upgrading my dual PIAA horns:
    Ordered a new set of Chinese replacement Zuma 125 headlights with H4 buckets instead of the stock BA20D reading lights.Wired it up to two relays to supply direct 12v power from the battery via an Eastern Beaver switched harnessWired in a 3rd relay for future fog lightsReplaced all connections with waterproof connectorsReplaced the standard H4 bulbs with ADVmonster H4 R3 LEDsNow to test it at night!

    the frustrating thing is lack of verifiable reviews. You *know* that the $500+ shocks sold over here are made in China, perhaps by this same company. But there is  no way to be sure. And even if these turned out to be the best shocks ever(tm), there is no guarantee that they would be available a few months from now. Such a new way of doing business. Foreign to me.

    If I had to drop coin on something today, it might very well be something like these:

    I think there is more information here than I can possibly digest: :P

    Good quality scooter shocks
    Looking ahead, one thing I would like to improve would be the overall handling of my Chinese scooter. Not handling in terms of racing, but rather something that would take some of the "harshness" out of the inevitable potholes I encounter. I've gone from 120/70-12 to 140-60-13 tires & rims which offer a slightly bigger diameter than stock. I may play with tire pressure a bit too to see how that helps (or not). But I'm thinking I should start with the rear shocks first as it is pretty much a given that the shocks supplied are certainly junk. Mine measure 320mm, which I assume is a pretty stock length for such scooters.
    I thought this was a pretty good intro to the subject: https://rideapart.com/articles/suspension-setup-rebound-compression-damping.
    Thoughts?

    I think folks who criticize social media are actually revealing something deep about themselves. Just sayin'

  14. MJSfoto1956 added a post in a topic Typical 150cc GY6 Switched 12v DC Circuits   

    I have verified that the highlighted circuits match my bike. The rest is unverified for my particular 2016 Jiajue 150cc. From what little I know of the Chinese, it is not surprising that a later "DC" bike's wiring would be based on an earlier "AC" design -- think of it as a typical hack taking the path of least resistance. As I adapt my particular system and discover deltas from the diagram, I will update my version of the diagram, with the eventual goal of it being 100% correct. I feel that given the way the Chinese glom together parts apparently on an ad-hoc basis, it is the only way to be sure of what you have. FWIW, I'm not saying my bike is not "DC" -- I'm merely saying that so far it appears to be "AC-style" but trust me: I would certainly welcome the simplicity of a clean DC-only solution! It may very well turn out that way. Fingers crossed. (As I said, I'm hedging my bets). More later. Thanks for the feedback.

  15. MJSfoto1956 added a post in a topic Typical 150cc GY6 Switched 12v DC Circuits   

    I can't agree with this. I *DO* think the Chinese are slowly modernizing their scoots, but with a primary emphasis on eScoots not ICE. Older scoot's headlights are almost universally 12VAC not 12VDC notwithstanding your experience on the matter. The Taiwan folks were the first to upgrade to a DC-primary system a few years ago because of the benefits of LED lights, but given the new emphasis on electric bikes I'm sensing things have been somewhat frozen in terms of change/development in the ICE world. The Chinese ICE bikes are hit or miss WRT AC vs. DC. For example, my CDI is definitely of the "AC" style and my headlights only turn on when the engine is running -- conventional wisdom on various forums says I must have "AC" driven headlights. I'm hedging my bets. 
    P.S. I never said this diagram 100% matched my bike. I simply wanted to convey that the circuits highlighted have been verified to match my bike. The rest is as of this moment conjecture given that the base drawing is a Jonway 150cc and my bike is a Jiajue 150cc. For just one example, I don't have an oil gauge.
