Jake,
Make sure you have checked and lubed all bearings, wheels, steering head, pedal and clutch shaft, if you have them, freewheel, etc.
Check and lube all your cables, levers and any other attachments that look like they need it.
Do a plug chop and verify that your mixture is good.
Take enough tools with you to repair a flat tire and inflate it. A spare plug and plug wrench and enough wrenches to tighten things that may come loose. A small bottle of 2 stroke oil and some way to measure it.
Go riding and have fun.
Ron
