Opening Up Cub’s Power Potential (airbox, gearing, FI)
Hello, fellow enthusiasts.
In enjoying my new 2023 cub, I’m being reminded of why I typically evade stock FI bikes. For the most part, the populous in the Asia-Pacific region drives Honda Dreams and Waves, which I find to be much ‘zippier’.
The bike has an aftermarket exhaust on it but stock airbox and gearing. Have you heard of anyone going down a tooth on the front sprocket of a 125 or 110 cub?
As you twist the throttle there’s a bit of lag, it only really gets responsive as you hit mid-to-high RPMs which is lots of fun yet not what I like in an ‘around towner’.
I presume the engine is the same as the CB110, but is the FI as well?
I suspect the bike is running lean. I looked at the dynojet website and there are precious few maps, most using stock airbox, rather than a Uni filter. Has anyone swapped the actual jet itself using the stock map? Then no need for a pricey dynojet nor a custom tune?
Appreciate your advice 🙏
