143cc Race Head V2, Upgrade Kit:

  • Race Head V2 – Roller rockers, 30mm intake valve, 24.5mm exhaust valve,
  • 27mm intake port, 23mm exhaust port (valves installed).
  • Race Camshaft V2-1 for Race Head V2
  • Lightweight high compression domed 60mm piston with rings, pin, & clips
  • Head gasket kit – includes the cylinder head o-ring set and an exhaust gasket.
  • Race Head V2 Intake Kit

This kit is to upgrade the cylinder head on KLX110s with a 143 kit installed to our new Race Head V2.  While the 143 bore kit provides a nice power gain over stock, wait until you try this upgrade!! The new head may appear to be the same on the outside as our other race head but internally, it has gone through numerous changes.  The addition of forged aluminum roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. Both valves are 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. Unlike other kits, our head gasket kit also 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!

Important Note 1: If you have a 2010 or newer KLX110, you will also need our TBW0645 cam sprocket.

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 from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.

Decent for the price. Instructions suck but most people should be able to figure it out. More below.
Color: Black, Size: 6 Panel, Color: Black, Size: 6 Panel
SUMMARY: 3 stars from me because it's firmly average. It's fine for the price. Assembly and materials are alright but I can see some caveats depending on your circumstances. Assembly instructions do a subpar job of pointing out some details. ASSEMBLY INSTRUCTIONS: Maybe it's because I'm autistic and/or building model kits and assembling stuff is my jam, but I honestly thought people were exaggerating when they were complaining about the instructions and I'd be able to flex my ~superior assembly skills.~ I was wrong! These instructions genuinely suck, and whoever is responsible for making them should be ashamed. The instructions do a poor job of calling out some details regarding orientation of parts, and some of the images do not actually match the physical parts. For example, it does not really outline the assembly of the end panels clearly, and I can see someone accidentally using the wrong poles. I've drawn over a photo to show what you should do to try and make it clearer. Additionally, the manual shows a flathead screw for bolting the feet into position, but the actual screw is not a flathead. It also does not point out the counterbore, so if you aren't paying attention you may put the foot pads onto the wrong side of the foot. It's also missing the fact that you need to use another one of the plastic pieces when you finish assembling a panel. ACTUAL ASSEMBLY & MATERIALS: To their credit, all of my bags were clearly labeled. The assembly process wasn't difficult. It's mostly just tedious and requires a fair amount of space. I was able to assemble it by myself without any real difficulty. However, the way it's assembled means two things. One, the fabric parts aren't removable without disassembly. So if you want to use this in an environment where they would require cleaning, I would seriously recommend looking for another option. Or, you could buy this just to use the frame pieces and then somehow buy or make your own fabric pieces designed to be removable with velcro or something. Two, because of the materials I really don't have a lot of faith in this thing surviving disassembly and reassembly. Like a lot of sorta-cheap-but-convenient furniture, it uses those spring-button connections and plastic inserts with self-tapping screws. Those things are not really meant to be disassembled and rethreaded. It also relies a lot on the tension of the poles and the fabric to keep everything rigid and squared, which I think puts a lot of pressure on the aforementioned buttons, plastic inserts, and the hollow metal rods. So I feel like that will also cause issues with disassembly and reassembly. Basically once this thing is assembled, it's not really meant to be disassembled. The best you can do is spot-clean the fabric if you need to. Speaking of the fabric, I didn't see any labels on them or anything in the manual that says what they are, but they feel like some kind of polyester. They generate static electricity pretty easily, and pet hair and debris sticks easily. So that's another downside of them not being easily removable. For the most part it does seem pretty stable. The poles seem to be pretty uniform in length so they're all making contact with my floor. Obviously this isn't structural so it shouldn't be supporting anything, but the two main feet seem to be doing fine with keeping this thing upright. CLOSING THOUGHTS: Really, it's fine for what it is, but it could be better in a lot of little ways and the substandard quality of the instructions just seems unprofessional to me, which is why I'm being so harsh with my rating. Depending on your needs and environment you may want to consider a different option. Preferably one that is made to be disassembled with better materials, and/or one with fabric pieces made to be removed easily.

Not as it seems
Color: Black, Size: 6 Panel
these are awful... Each individual panel is fine, but when you put it together it can barely stand up, and the clips that hold it together keep popping off. Steer clear of this item.
