Questions & Answers

  • Can i change my cam to a stage three without having to change anything else or what should i do?

    By: nick

    When you install big bore cylinder kit it's recommended to change your cams as well. Any time you change the displacement of the engine, you should match the valve diameter and cam lift to to the bigger set up if you want to get the most power out of the new set up.

    Let us know what you'r working with and our team will be happy to help you find a complete kit with everything you need to get the most power from your ride.

  • Big bore kit additional parts

    I have a 2007 yz450f. What aother engine parts should I change to get the most out of the big bore kit? Thanks.

    By: Guest

    I would suggest looking at the Hot Rods Stage 2 Camshafts for your 2007 Yamaha YZ450F. When used in conjunction with the Cylinder Works Big Bore Cylinder Kit this will give you a larger boost in performance over the stock cam profiles. You can find those cams by simply searching our store for "Hot Rods Stage 2 Exhaust Camshaft" and "Hot Rods Stage 2 Intake Camshaft"

  • 2007 crf150rb when using this big bore kit do I need to replace my cylinder head as well??

    By: Jeff

    The CRF150RB's big bore cylinder kit works with the OEM cylinder head. There's no need to replace it. Though, since you've got everything torn down, you might as well have some head work done as well and take advantage of that extra displacement.

  • I'm looking at getting this bore kit for my 2009 Kx250f what else should I also get new cams as well

    By: Tim

    Cylinder Works Big Bore Kits are designed to work with OEM or any aftermarket cams that fit the OEM cylinder head. Just be sure to choose the correct cam for the kind of power you're looking for and you should be all set!
