CRF270cc Cylinder Works/Hot Cams/FMF–
Cylinder Works is making a name for itself with stock looking big bore cylinders that not only look good, but they work great too! For a modern 250cc 4-stroke it is all about making the most power you can. A big bore kit allows you to do just that. The big bore kits make a bit more top end power than a standard bore bolt on mod. However, the most important thing it does is shift the power and torque curve much earlier. This allows for a 250F to now have that bottom/mid that it can lack. The good news is that these kits are only $649.95 with a complete piston and gasket kit. No core charge (you keep you stock cylinder).
On the dyno, the numbers are very impressive (nearly 6 hp gain and much more torque).
Who are these big bore kits for?
A fast “A” or “B” rider who wants to have a fast practice bike for way less money than building a full mod. Also the maintenance cost on the valve train is less because you don’t have to run a gnarly cam that requires stiffer valve springs. A Hot Cams stage-2 cam works great with this package.
Vet rider/racer—Any Vet rider who is not riding a 450 and would like more power. Vet racers don’t have to worry about any rules in the run what you brung vet classes.
Those who might be “ethically challenged”. Yes, there are those who might say “it’s not cheating if you don’t get caught” or “it’s still not as fast as Barcia’s 250 so I am ok with it."
Could it make even more horsepower? You bet, with Head Porting, Hot Cams builder Series cam and good VP Race fuel you would be making big power.
