Is this a result of running at a higher rpm than the factory intended or is it the constant up and down torque demands of racing around a track? Dan
Hey Paul. So I guess it didn't "inhale". Always good to send up a distress signal (cloud of dust) when the guy with the bucket finds the fan!Enjoying this thread (maybe too much), so I'll let you get back to the tech part. Thanks for posting....bert
Paul, What are your options for addressing this weak spot on the 175 cranks? I know very little about modifications for racing applications but am very curious on what could be done to modify a stock crank. Is this a result of running at a higher rpm than the factory intended or is it the constant up and down torque demands of racing around a track? Dan
Hey Vince,I have thought about using stepped pins for the connecting rod pins (well at the insistence of the guy who usually builds my cranks). He thinks it would be easier to press together if the pins were stepped so they won't "push thru". I'm not convinced but will try a couple cranks with 20mm holes. I've thought about indexing the center pins like a Kawasaki triple with key ways also.I think I may have exceeded the max on photos. I can't seem to post anymore. I'll try and figure it out.paul
