Here are some specific steps on how to fit an Evo motor into a Paucho frame:
1. Widen the frame. This can be done by cutting the frame apart and welding in a wider section.
2. Modify the frame to accommodate the Evo motor's mounting points. This can be done by drilling new holes and welding in new brackets.
3. Modify the exhaust system to fit the Evo motor. This can be done by cutting and welding the exhaust pipes.
4. Once the frame and exhaust system have been modified, the Evo motor can be installed.
It is important to note that these modifications are not for the faint of heart. They require a high level of skill and experience in metalworking and mechanics. If you are not confident in your ability to perform these modifications, it is best to have a professional do it for you.
