Hi I have a 770 I've posted on here about before. It has stock internals, but hotter coil, tuned timing, and a tuned carb. I recently took about 7 rings out of the governor spring. I don't have a working tach right now but I'm pretty sure I'm conservatively free revving somewhere between 2500 and 3000revs, maybe even a bit higher. I was wondering if someone would know a ballpark of how much horse power iI might be running... Before anyone starts in with Tue nay saying I have fabbed both a scatter shield for the clutch and fan for safety.it is a trusted tractor and well maintained I wouldn't have braved the modification if I wasn't sure no one would die... Thanks for any help
