Should I rejet after cam and piston?

[02grizzster]

Just had a MB cam and Wiseco 11:1 piston installed and i assumed I would have more low end. But for some reason it still has lag at the bottom. I hit the gas...pause and then go. I believe it has less pep than before I took it in and still won't wheelie and seems to struggle more pulling the front end up at all. I am now running 93 octane if that makes a difference. Any suggestions?

I do not have any experience with cams or hi comp pistons, but im thinking you would definitely need to rejet after a cam. The only reason a cam will give you more horsepower is because it allows more air and fuel into the combustion chamber. Its already giving you more air, but the only way to get more fuel with that air is to rejet the carb. I highly reccommend you donnot ride it until it is jetted properly. You are running lean right now which will cause your bike to run hotter.
