350cc Pro Moto-cross Engine Kit:
The following listed set-up is a guideline of what Patriot Racing would recommend using for a Banshee MX set-up.
Pipes:
Patriot Racing recommends Paul Turner mid range pipes for our MX motors. The Paul Turner pipes with our set-up has excellent low end power- a very strong midrange, but a smooth hit onto the pipe- providing for greater control and power tractability.
Carbs:
28mm Keihin PWKs. Easy and precise to tune, these carbs are ideal. By keeping the carb diameter smaller, the intake velocity and fuel atomization is much greater.
Reed cages:
We've found that V-Force reed cages with the Pro Design V-Force compatible intakes with the built in boost bottle works superbly for our MX set-up. The W style V-Force reed cage has smaller inlet passages which in turn creates for greater intake velocity. This intake velocity is crucial to good throttle response and sub peak power.
Cylinder head:
Aftermarket billet head with compression ratio to suit octane level. A wide squish band to provide for good low end torque. The stock cylinder head can be modified as well- the head is decked and the squish band is re-cut.
Ignition timing:
At a minimum the stock stator mounting plate must be modified to provide for at least 4 degrees of timing advance. The ability of the motor after cylinder porting alterations and the pipes fitted allow for a greater peak RPM- this higher peak does not suit the stock timing curve. We recommend 4 degrees advance for pump gas motors and 6 degrees for race fuel motors.
Cylinder porting alterations:
A MX engine is probably the most difficult to do correctly and net the desired results. A MX engine needs smooth tractable power, it also often requires good straight-line speed. Port velocity is essential in a good MX set-up. A fine balance must be struck between porting alterations that provide good power- but meanwhile retain good velocity for throttle response and crisp power. We spend a tremendous amount of time in correcting the transfer port angles and flow which then nets a consider boost of mid range power. The intake is reshaped- but not enlarged- to retain good velocity and fuel atomization. The exhaust port duration is crucial in ensuring the motor is able to pull sufficient RPM, but not too high that it creates a shorter power stroke and sub peak power falls off.

Is it worth the money?
It says modify and reshape exhaust does that mean it comes w/ an exhaust of your pick?
