## Description (the store's own text)

TBparts 143cc big bore kit, performance camshaft, Mikuni VM26, and carb kit for 2010-2016 KLX110s together in the best package deal! Starting with our 143cc big bore kit the performance gains are HUGE! It includes our all aluminum ceramic coated cylinder that is lighter than the OEM steel sleeved aluminum cylinder, reduces friction while improving sealing (increasing power), and provides better heat transfer (runs and cools down quicker). Paired with our 60mm high compression lightweight piston (7mm larger than the stock 53mm piston) and you have a great base for big power gains of over 50 percent. The cam in this kit is the best cam on the market in our opinion for a stock head 143cc setup. This cam works perfect with this setup making more power everywhere. Top all of that off with the +8mm VM26 carb kit that is port matched to the stock head and you cannot make more power for less! The larger carb kit cuts down big on intake restrictions and will make more power everywhere. This kit also includes all the necessary top end gasket. This affordable setup will really make your KLX110 fly! High quality parts and requires no machining to the cases or other modifications – bolt on and go!

**Note:** The cam is not a decompression cam like OEM, we have not had any starter issues from this.

Jetting Info – With the stock exhaust #20 pilot and 165 main jet are a good starting point.
If you have an aftermarket performance exhaust a 175 main jet is recommended.
If you are using anything over #22.5 for the pilot jet that is too large, additionally we have never used less than a 20 pilot on this setup.

**Key Features:**

- All aluminum ceramic coated cylinder, lighter than the OEM steel sleeved aluminum cylinder (reduces friction and improves sealing, increasing power), and provides better heat transfer (runs and cools down quicker).

- Head gasket kit, includes the cylinder head o-ring set and an exhaust gasket.
