    I've been looking for awhile and I finally turned up this. It's the manual to a Baja Reaction 150 with the newer VIN number. The newer VIN has a Howhit and the same gearbox as yours according to other buggy forums.

    I think you'll want the blue/yellow or blue/white wire coming off the coil outside the flywheel. The black/red wire coming from inside the flywheel is the 400V one.

    Do these engine specs help?
    9.2:1 compression ratio
    9.9HP @ 7500rpm
    13ft/lb @ 5500rpm

    Pulse + before the coil? What wire is that?

    I found this video off of an Amazon review. https://www.youtube.com/watch?v=iC1Dc8Mwusk
    I think the output of the CDI would fry the tach being it's around 400V. I was planning to use the trigger coil output (< 5V) when I buy one.

    Awesome mods! Gotta love cramming air horns where they're not meant!
    Is the tach fixed?

    Is it a short 90* hose that came with the carb? That one is just a vent. The downward-facing hose is just to keep dirt and water out of the vent.

    So it idles fine when it's warming up (auto-choke on) but it dies when the auto-choke turns off? That's not the main jet's fault. You need to adjust your A/F screw richer.
    The A/F screw affects the mixture at idle to 1/4 throttle.
    The position of the e-clip on the jet needle affects 1/4 to 3/4 throttle.
    The main jet only affects 3/4 to full throttle.
    And as for the fake carb, maybe you can cannibalize some parts off of it (jets, auto-choke, float, etc.), then chuck that thing at your annoying neighbors. Might as well get some use out of it.

    Tonight I took the CVT apart again so I could change back to my 14g sliders. The 12g/14g setup didn't "shift" like other forums promised, it just ate up my top end power like a set of 13g but that's a whole other discussion. While I was down taking off the exhaust, I thought I might show off my studs to @pistonguy. I like them a bit better than stock because they're beefy as all hell:

    While I was taking that last picture, a wire decided to fall on my safety glasses:

    Ahhhhh...So THAT'S why my speedo stopped working!
    And now some pictures of my gearbox:




    Heck, why not add the exploded view from the manual:

    Yup, I stripped the spark plug hole and exhaust studs. I own that one...
    I used an insert (not the heli-coil type) and tapped the inside of it to the spark plug head. I also used 5/16-18 studs for the exhaust. It ain't pretty, but it works. I know I could use a new head. But there's other things before that, like the cracked frame. And heck, it's not like I can keep this thing spotless for 2 years straight like a scoot driven on a road. It's a buggy!
    I can degree the cam. I haven't done this one yet, but I did on my other gokart that has a GX200. I have indicators and printed-out degree wheels. I will do this in my Tong Jian vs Scoot thread when I get the chance.

    Were you running this PCV when the seal blew? If not, I'd say that's the culprit.
    BTW, did you use an old throttle piston to make the PCV? That's awesome!

    What was that PCV delete that you were talking about? Did you eliminate the check valve and make it a straight-through breather, or did you cap off the barb? Even with good rings if there's no breather, the crankcase will pressurize enough to blow seals.

  14. TheDullCarbide added a post in a topic Valve lash / clearance numbers   

    Sorry I was just spit-balling some ideas. I wasn't really taking a scientific approach at my statements. I'll think a little more before I post next time...
    I see the question you were asking, @pistonguy. Sure the compression ratios are different, but that would affect head volume/shape and deck height and not valve lash (to a certain degree).
    Manufacturer politics has much to do with it too. Heck, we all know the engine will run just fine with a plug gap of 0.020" or 0.030" but one manufacturer might prefer 0.026"-0.028" and another 0.022"-0.026". That would also have to do with compression ratio, probably more so than valve lash but you get the point.
    And I run 20W-50 in the fall on my GY6.

    Just took a pic of the worst spot on the driven. I have no idea how these nicks happened. I measured the depth of the gouge in the picture to be 0.003" deep. All the others are much smaller (less than 0.001"). Could this be the issue?
