Changing to S-7 nozzle(need help)

[sandrider02]

I just bought an S-7 nozzle for my 01cr250 and need help on how to install it. I think I've heard that it's called the jet needle but am not sure, also does the main jet screw into it. What do I need to do to install it. Any help would be great.

Yes, the main screws into it. If you remove your main, you will see it. Simply thread it out, just like the main, and install the new one (don't forget to reinstall the main ;) )

ya take the main jet out with a 6mm socket. They use a 10mm socket to remove the nozzle. Its very easy and you don't even have to remove you float bowl or carb.
