The Suzuki TS185 engine is a larger and heavier engine than the TS100 engine, so it is unlikely that the TS100 frame would be able to hold the TS185 engine without significant modifications. The frame would likely need to be reinforced in order to support the increased weight of the TS185 engine, and the suspension and brakes would also need to be upgraded to handle the increased power and torque of the TS185 engine. In addition, the electrical system would need to be modified to accommodate the TS185 engine's different electrical requirements.
Overall, it is not recommended to attempt to install a TS185 engine into a TS100 frame without significant modifications and engineering expertise.
