If you are just installing a performance air filter, you will need to raise your main jet about 4-6 sizes over stock.
If you are also replacing your CDI and Coil with our Digital Smart Combo too, you will raise your main jet 8-10 sizes over stock.

Torque Spring

We can upgrade your stock 1000rpm main spring with either a 1500rpm or 2000rpm spring. This will increase the rpm's needed before you start to roll, thus increasing your low end torque.

The why's and hows

If you have the money, it's fun to upgrade just for the sake of upgrading but for most of us, we just need to keep our rides in good repair and that can be expensive enough! However, you CAN upgrade some things when it comes time to replace them anyway due to normal wear and tear and actually SAVE money in the process!
