350cc Hot Trail Engine
This engine configuration with modest cylinder porting alterations and the right combinations of exhaust, intake, and head design makes this a smooth pulling motor.
Pipes:
We highly recommend DMC pipes. With slightly more mid range and smoother power, we prefer these pipes over most.
Carbs:
28mm flat slide carbs- either 28mm Keihin PWKs. The flatslide carb gives excellent throttle response. The inlet diameter is "right-sized" not too large not too small.
Reed cages:
V-Force reed cages with billet intakes. Or the stock intake boots. The V Force cage with its W design provides for superior intake velocity, which equates to good throttle response.
Crankshaft:
The heart of any good engine is it crankshaft. We highly recommend for ANY Banshee to have the stock crank trued and welded.
Cylinder head:
An aftermarket billet head with domes for a 15:1 compression ratio on race fuel is the best performing. For premium pump gas motors we modifying the stock head to a 13:1 compression ratio.
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:
We work with the customer to determine their exact power delivery needs- then we apply our experience and knowledge in reworking the cylinder porting arrangement. The transfer ports- the choke point on any Banshee cylinder gets special attention crafting them to suit the motors needs. Continuing the intake is reshaped providing for excellent intake velocity which equates to crisp and robust throttle response and snap. The exhaust port then is re-cut for the required duration as well as the required width and the ever important shape- the sum of the cylinder porting alterations create a very wide powerful delivery of horsepower and torque.
