TBparts 64mm Big Bore Kit: Once you already have the a V1 or V2 race head there is no replacement for displacement! This 64mm big bore kit increases your KLX110 engine to 165cc (If you have a TBparts stroker crank even better – 177cc). The kit also includes an all aluminum ceramic coated cylinder. 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). Top end gaskets are also included. High compression domed 64mm piston comes with rings, pin, & clips (will safely run on pump gas, 90-93 octane). Mikuni VM26 with TBparts manifold/carb kit: It is hard to beat the consistency and performance of the VM26. Paired with our larger intake manifold for the race heads. 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. **Includes:** - TBW1250 - 64mm Cylinder - TBW0503 - 64mm Gasket set - TBW0590 - 64mm Piston kit - TBW0321 - Throttle cable - TBW0362 - Intake Manifold - TBW1354 - Main Jet Kit Sizes 195, 200, 205, 210, 220, 230, 240 - TBW0399 - VM26 606 Carb 190 Main 22.5 Pilot Included - TBW1430 - Air Filter - TBW0305 - Ignition Cover Gasket **Case boring required:** Cylinder skirt L x W is 15 x 66mm. 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. Case boring creates a ton of metal shavings and precision. Its best to completely disassemble the engine when you bore a set of cases. That way you can ensure the cases are 100% clean for reassembly. **Install NoteS:** See TECH DATA section where you can download the shop manual. 2010 and newer KLX110: You will need cam sprocket TBW0645. If you have a V1 or V2 head you should already have this installed. Use Supplied 1mm thick base gasket for 64mm bore kits on all KLX110. ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
