Crf230f big bore kit

In November,I decided to do a big-bore kit on my own because no one had yet made one for the F.

In short, the Athena CRFF big bore kit check price on Amazon is a great upgrade if you want more torque and horsepower, or if your top-end needs to be rebuilt. The kit comes with everything you need to replace the piston and cylinder. Honda has been making air-cooled four-stroke trail bikes for decades. The CRFF still uses one of these tried-and-true engine platforms. Will adding a big bore compromise the reliability or durability of my bike? Being stranded out in the middle of nowhere because of a broken dirt bike is frustrating and potentially dangerous.

Some time ago I remember reading some discussion about the possibility that some Brazilian engine builders were using a wider stud spaced engine barrel Zong. I did some searches but couldn't find the thread. I'm thinking of my next project, and if they are doing it, it might be a LOT simpler to get some parts and ideas from Brazil. Just wild brainstorming options at the moment. It doen't help me much with my question. Look like they may have used the original cylinder with some mods. Can anyone who has has intimate experience with this engine comment on the possibility of welding and retapping the cases for the wider stud spacing and lining up of the cam drive and anything else top end oil supply?

A high-quality big bore kit will have proper tolerances that provide increased performance, but also be just as durable as a stock engine.
