Kuni0 Posted January 30, 2019 Report Share Posted January 30, 2019 Hello everyone, I was hoping I could get some advice from the great people here and get some opinions/ options to mildly hot-rod my Guzzi motor. Because of some transmission issues, I had to pull the motor from my Guzzi to diagnose (which I soon discovered was likely caused by literally disintegrated clutch plates) and I figured with over 45k miles, might as well take the opportunity to service and modify my Le Mans as I saw fit, especially with trying to squeeze a little more power out of the motor while still maintaining everyday reliability. What are the opinions on Cams/ Valves/ Springs/ Pushrods, anything else I might be missing? I was looking heavily at the Megacycle 620x10, but I'm unsure of the modifications needed for it. For street use, I've heard the 620x9 is better? Ghezzi Brian also sell a camshaft, but don't list the specs so if anyone knows anything about that I would be interested to hear. I know valves/ springs/ pushrods would help with the motor (and in some cases are necessary for a hotter cam) but I'm pretty lost when it comes to this aspect of Guzzi tuning. I know for sure I was going to try and find a Roper plate and get the heads ported and polished. I've decided against Hi-comp pistons because of how crappy the fuel can be here in California. This will be a street bike through and through! I don't want to make sacrifices to reliability as I want to continue to tour on it and put thousands of more miles on her. Though I'll take it to a professional when needed, I would like to do most of the work myself when possible. Thanks in advance! Link to comment Share on other sites More sharing options...
