It´s about the oil lubrication system on my H27A engine. I fixed my engine recently and the oil pressure is too low. ¿Do you have a diagram of the lubrication passages and components?

XL7 Technical Bulletin Division: Automotive Section Title: Engine Category: Technical TSB No. TS 25 03211 Technical Service Department Dealership Circulation – Initial and file: Service Manager Parts Manager Service Advisor Technicians Suzuki bulletins are intended for use by professional technicians, NOT a “do-it-yourselfer.” They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your authorized Suzuki dealer for information on whether your vehicle may benefit from the information. Suzuki reserves the right to change technical specifications at any time without prior notice.
