As the bike is a relatively unknown since you just bought it, I'd suggest an overall inspection and check.
It was the same way with mine when I bought it.
I had all the fluids changed (coolant, brake fluid, oil/filter), then had the valves checked.
I checked the brake pads, air filters, etc.
I looked at the condition of the rubber items (tires, hoses, etc).
I looked at my clutch plates and measured their thickness and they were well within the factory specs, so I returned them to operation.
When I had her apart to replace the bodywork and wiring harnesses I made sure all the electrical connectors got a liberal dab of dielectric grease to weather-proof the contacts.
So far she's never failed to start and run. The valve shims hardly need swapping.
In all, a very stoutly built engine and well built bike.
