TB Camshaft, Performance Roller & HD Valve Springs – KLX140 Use with Roller Rockers only

Get more power and stronger performance out of your KLX140 with the TBparts Performance Roller Camshaft and Heavy-Duty Valve Spring Kit.
This camshaft is designed specifically for use with TBparts KLX140 Roller Rockers (TBW1710) and should not be used with OEM-style standard rocker arms.

Built to make as much power as possible without sacrificing low-end torque or drivability, this cam features significantly more lift, ramp speed, and duration compared to the stock cam. The result — more fuel and air flow for noticeable horsepower gains, especially on big bore and stroker setups (170cc+).

Each cam is manufactured on a brand-new core (not a regrind) and fitted with NTN bearings made to OEM specs for perfect fit and long-term reliability. Now paired with heavy-duty valve springs, this setup ensures stability and performance at higher RPMs.

Key Features:

• Increased valve lift for improved air/fuel flow and more power
• Faster ramp speed for quicker valve action and stronger response
• Extended duration to keep valves open longer for enhanced combustion
• Brand-new camshaft (not a regrind) with OEM-spec NTN bearings
• Includes Heavy-Duty Valve Springs for reliable high-RPM performance
• Works great with stock or modified KLX140 engines (with roller rockers)

Installation Notes:

• For use with TBparts KLX140 Roller Rocker Arms (TBW1710) only

• Do not use with OEM-style rocker arms (standard follower radius)
• Valve Clearance: No less than 0.003″ on both intake and exhaust sides
• Camshaft Bolts: Reverse-threaded — turn right (clockwise) to loosen/remove
• Torque: 87 in-lbs with red thread lock

Upgrade your KLX140 with this race-proven cam and valve spring combo for a noticeable performance boost and unmatched reliability at higher RPMs.
