Barnett clutch for the 1125 DOES work in the 1190. I'm using a heavier spring than what they supply,that makes finding neutral sometimes a bit of a pita,but no slipping! Damn easy pull clutch springs sucked. Also supersprox DOES make a steel rear sprocket! Its made in Europe and has to be fabricated for you but its only 40$! Plus shipping. Email em and they get back to you next day
