You'll be fine. Dont worry about engine timing. There's not much to adjust. When i do full tune ups on customer bikes I do: Oil, oil filter, spark plugs, clean or replace air filter, flush out brake fluid, check tire pressure, adjust chain slack, clean and lube chain, adjust throttle and clutch cable freeplay, check brake pads, check coolant level, adjust idle. Might seem like a lot but its not. its good to get in the rhythm soon. OH yeah, dont worry about the fuel filter, its inside the gas tank and cant be replaced. If you have proper tools, you can do a throttle body sync as well.
