Engine performance can be altered drastically by porting your cylinder (2-cycle) or head (4-cycle). The skilled engine builders at LaBaron's Power Sports have years of experience modifying cylinders and heads to squeeze every drop of horsepower out of them. Whether you desire to build a fire-breathing race engine, or want to modify the power delivery of your weekend trail machine, we can develop a porting package, along with other engine modifications, that fit the needs of your specific application.

Frequently Asked Questions

Q: How effective is porting on its own?

A: There are more horsepower benefits for 2-strokes. 4-Strokes require other modifications to maximize the porting work (exhaust, camshafts, high compression pistons, etc.)

Q: What kind of horsepower gains can I expect? 

A: Typical results are 2-4 horsepower.

Q: Is it possible to lose horsepower porting?

A: We have seen several amateur porting jobs that were ported incorrectly. Substandard porting usually can not be reversed. A new cylinder or cylinder head must be purchased.
