TBparts - 155cc Big Bore and Stroker Kit for KLX110 KLX110L 2003-Present

TBparts ultimate 155cc big bore stroker kit! The combination of the large V2-2 camshaft with the Nibbi PE28 gives you the highest powerband possible for the ultimate race bike combo. You cannot make more horse power with any other bolt on kit for less! This kit was put together for the ultimate 155cc performance package and is perfect for the 155cc stock mod mini MX race class.

TBparts V2 Race Head: Starting with the addition of forged aluminum roller rocker arms and our V2-2 camshaft. Not only do the aluminum roller rockers free up big horsepower, but you can also run much more aggressive cam profiles with roller rockers for even more power. Next is the bigger valves 30mm intake and 24.5mm Exhaust. The intake and exhaust ports are equally as improved at 27/23mm. Both valves are stainless steel too (21-4N material). The valves also come installed, complete with high lift heavy duty valve springs.

TBparts 60mm 143cc Big Bore Kit: An all aluminum ceramic coated cylinder. No case boring required, bolt on! This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). Forged, high compression 12.09:1 (when combined with the V2 Head and crank in this kit) domed 60mm piston comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane). Top end gaskets are also included.

Nibbi PE28 with TBparts manifold/carb kit: Nibbi stepped up the PE28 carb game! Starting with looks, they come hard anodized black. This helps with corrosion resistance, wear resistance, insulation, heat resistance and hardness/strength of the carburetor. The lightweight hardware is also anodized. For performance the entire air passage from the intake bell to spigot is polished, you feel the difference! Another huge benefit is the splash guard. It keeps the engine operating smooth under bumpy riding. Making them an AMAZING value overall! Paired with our larger intake manifold for the V2 race head. This will give you some of the best throttle response and consistent reliable power on the market! We also include a low profile air filter and extended throttle cable for the KLX110.

55mm Stroker Crankshaft Kit: There is no replacement for displacement! Increase your displacement, torque, and power by replacing your stock crankshaft with this one. The kit also includes a new cam sprocket and DID Cam Chain. No modifications are needed. All necessary gaskets included.

Note: 
TBW0473 cam is stronger through the low and mid range with a little less on the very top.
TBW0577 cam is a little stronger on the very top with less through the low and mid range.

Case splitting required: If you don’t have experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki or Suzuki dealer. Installing a crankshaft requires delicate technique.

Note 1 – If you have an 07 or older model with the original OEM Output Shaft we highly recommend also purchasing our strengthened Output Shaft available in this section. The 02 thru 07 Output Shafts were very weak and would often snap. They have a oil hole drilled straight through the shaft at the opposite end of the sprocket, so best to update while you have the engine apart.

Note 2 – We also recommend our heavy duty clutch plate kit TBW1035, for best results convert to full manual.

There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki or Suzuki dealer. We also have a link on our website in the INFO section under KLX110 where you can download the shop manual. The parts are installed in the same manner as the OEM parts.
