The kawi on one of my 21" proline has had it. I am tired of fixing head gaskets! I want to take off the Kawi FJ180V and re-power with Honda GXV160. Can I do this my self? Is it as simple as un-bolt / bolt on??? I know I will need to change the cables. These 21"s come with both motors factory, so are the holes there to bolt on? I am slightly mechanically inclined. Am I getting in over my head? Any advice? This will be a winter project, so it could be...uuhhhh fun... Thanks for any advice / experience!
