I would think so. But like others have said rejetting isn't that big of a deal. I was very apprehensive too when I did mine. But I did my research on here and found a few videos that helped. As others pointed out to me at the time, it's good to get in there and learn more about your bike. So in hindsight I'm glad I did it.

I broke my bike down after work on a Friday evening. Rejetted the carb the following morning (10-minutes) and put it all back together.

 

ya man thanks for the help I said screw it and I am getting ready to open up the bottom of the carb I didn't take it out just twisted it in the bike
