What kind of basic info do you need? I have access to a manual, I could look something up for you. As for p/n's, I've never needed a manual to buy parts, I just walk in or call any parts store and ask for something, they do the rest. The p/n's listed in the manual are going to be dealer numbers(and they may not be good, Honda for example will have a new release of the same part, and give it a new part number, then discontinue the old number), so places like NAPA/UAP, Advanced Auto, CarQuest, etc. are going to have their own numbers. Suzuki numbers will not be of good use.
If your rig is running good, and you're only looking for basic, change the air filter, oil, oil filter and fuel filter, then mark down your milage so you know when it was done last.
