We have listed Installation Tips and Guidelines for many of the Sparks Racing Products as well as jetting specifications.

Please call before shipping anything to Sparks Racing. We will not accept any packages without prior authorization.

You will also see that there are Motor Packages listed. Use these sheets as a guide for some options to build your Honda TRX 450R. Some of the items listed on the sheet can be substituted, postponed or even omitted where some items must be used for combatibility with other components. Please call the shop during business hours to discuss in detail the engine build you are planning. We can also supply these components to be used by another engine builder if you so desire. We welcome your questions, just call (661) 872-4343 M-F 8:30am - 5:30pm PST.
