mx engine set up

[450r51]

im trying to build an mx 450r, i have all the essentials, ie pipe, nerfs, jetting, and i have an axle, and tires all around, but i was wondering what i need to get for my engine, like i said i have a full yoshi ti-trs exhaust, and 175 main jet and no air box lid. any advice would be nice

The next step would be a cam hot cam stage two for a tighter track or hrc for a more open track then a higher compression piston.

Right now I have a hrc and 13.1 piston with head porting. Im pretty happy with the power but when im on a tighter mx track I need to keep the rpms up to break the tires loose in the turns.

Depending on what people say about the dyna fs ignition il either get that or the crf ignition next with the crfs Fcr carb.
