    Heavy Fork Spring Option

    I know about a guy that runs Xr100 springs on his trail. Pretty sure they’re the BBR ones as well.

    HONDA CT125 Big Bore Kit

    Hmm, never noticed that one!

    HONDA CT125 Big Bore Kit

    148? Or 143? I would go with the 170cc/min injector either way.

    OEM Honda front rack

    In my defense, I didn’t know it was a shortcut at the time!

    OEM Honda front rack

    I have the OEM front rack+ windshield on my 2021. The only additional part you need is the 2023 meter stay. I never changed the “top bridge”.

    HONDA CT125 Big Bore Kit

    That’s interesting @JPMcGraw. I had similar MPG with my failures, now at 112 and 116 the last 2 tanks. I also pick up a slight gas smell from the exhaust when I get to a stoplight.

    HONDA CT125 Big Bore Kit

    Here’s an update on the current setup (S238 cam, 142 BBK, EFIE @ 260mV, 170cc/min injector, and Takegawa air filter) After 60 miles easy around town riding settling in the new injector, I hit a 150 mile ride to over 10K elevation. Multiple minutes of 55+, engine didn’t sieze…. unlike my other...

    HONDA CT125 Big Bore Kit

    Last tank calculated 117mpg. I can be easy on the MPG, but it's still too high I reckon. 260mV on the efie with the genuine 140cc/min PCX150 injector. I am going to throw in my 170cc/min yuminashi injector and see what happens. Typical ECM break in of 40-60 miles taking it easy again I guess.

    Takegawa drop in Power Filter tested

    I have that filter as well. threw it on between my 1st and 2nd seized piston. Nice info that it was raising your AFRs

    testing the efie with an actual wideband

    you know you wanna make an AFR table with different efie settings for us

    testing the efie with an actual wideband

    @m in sc you mean 0.26V or 260mV, correct?

    Yuminash S238 camshaft

    happened to me on my s238 as well. just find a socket that fits over the inner bearing race and tap it down with a hamma

    HONDA CT125 Big Bore Kit

    With the increase in bore and the increase in fuel, I would expect a bigger decrease. My Tacoma actually increased MPG with a supercharger!

    HONDA CT125 Big Bore Kit

    Even with my new injector and EFIE @ 250, I am still getting 113mpg. Doesn’t seem right. Stock 125cc I used to get around 125mpg.

    the 4 point seizure happened to me twice. Most likely from running too lean. I posted about it a few pages back.

    Out with the ‘21, in with the ‘23

    Made a typo on the gearing. It is correct now. Japan Webike is where we all got ours. But that was before Honda brought the new model to the US. I imagine you can get the parts direct from Honda now in the US. Check out the thread over at advrider

    Out with the ‘21, in with the ‘23

    Here are the differences as I know them: New JA65 engine, which is actually from the Honda Dax 125. We don't have those in North America but I have seen many in Thailand. This new engine has a higher compression ratio (10:1 vs 9.3:1) and an oil filter, user reports seem to say there's not much...

    HONDA CT125 Big Bore Kit

    I do not believe that to be a genuine Honda part, but that doesn't mean it isn't an aftermarket equivalent. I have a PCX150 injector coming into my Honda dealer this Friday, I will post a picture. It is a genuine Honda part, I think the only PCX150 injector you can get straight from Honda in...

    Two year update on BBK here in Thailand...

    What are your reasons for preferring the 23 to the 21?
