Trail Bikes / TB Parts 143cc/60mm Race Head V2 Upgrade Kit - GPX/YX150/160 - TBW9028
Description:
- Race Head V2 - Roller rockers, 30mm intake valve, 24.5mm exhaust valve, 27mm intake port, 23mm exhaust port (valves installed).- Race Camshaft V2-2 for Race Head V2 (TBW0577)- Lightweight high compression domed 60mm piston with rings, pin, & clips- 60mm Head gasket kit - includes the cylinder head o-ring set and an exhaust gasket.
This kit is to upgrade the cylinder head on stock YX/GPX 150 or 160 engines to our new Race Head V2. The addition of this new head will dramatically increase the performance of your stock engine!! This kit includes our new Race Head V2 and while the new head may appear to be the same on the outside as our other KLX110 type race head, internally it has gone through numerous changes. The addition of roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve is now stainless as well (21-4N material). This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable for the privateer rider. Also, included is a piston with bigger reliefs to match the larger valves of the new race head. Additionally, our head gasket kit includes a head o-ring set and exhaust gasket so you don't have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and require no machining to the cases or other modifications - bolt on and go!
Add a stroker crankshaft for even more power!
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 in this section or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.
