For the time being, yes. My son had never ridden until I got him this bike a couple of months ago. Once he progressed past learning to ride, I wanted to creep up on the power for him. I understand there is a lot of power to be had with higher compression pistons, ported heads & cams... or just get a bigger bike. I love to build and work on things, so who knows which route I may end up going.
Just to add to the conversation, I've read a couple of theories on sizing carbs while maintaining good "rideability". Love to hear some input from those with more experience:
1. To keep up velocity, stay 1 to 2 millimeters less than the valve head diameter, but never larger than the valve diameter. The intake valve for the CRF125F is apparently 25.5mm (same valves as the CRF110).
2. Take the carb size & divide by two. Square your result to determine the engine displacement in cc's for good performance with stable jetting:
20 mm → 100 cc
22 mm → 120 cc
24 mm → 145 cc
26 mm → 170 cc
28 mm → 200 cc
30 mm → 225 cc
32 mm → 255 cc
I'm still interested in the whole "airflow past the venturi requiring more fuel, even with same cc's" information. I may make a trip to the library and tinker with a 22mm carburetor just for fun. Still think I need a CRF230F for me though
