I have a 2006 750 and in second gear between 4K and 5K RPM it seems to slip. That is the only gear it does it in and only between 4k and 5k RPM. Local bike shop tuned it up and carb was way out, so he said that should fix it. It did not fix it so I am thinking it's something to do with clutch or transmission. Love the bike just want it to run right. Thanks in advance for any help you can give me.
