WISECO KAWASAKI KX327 PROJECT: TWO-STROKE TUESDAY

On this week’s Two-Stroke Tuesday we give you the first look at our completed 2003 KX327 with Kevin Bailey and the crew over at Race Winning Brands. Kevin had lots of help from industry leading companies on the build but was the main person doing the garage work.  We keep the Kawasaki theme going in our 2-Stroke Behind The Build section with the complete story on our 1996 KX250 build with Western Powersports.

This 2003 KX250 started out looking like your typical Craigslist ad, in need of a “little” TLC. It was originally built as a project bike in the early 2000s, when these machines were still rolling off Kawasaki’s manufacturing line and onto showroom floors. Even though it was in rough shape when we found it, we knew we could bring it back to its former glory and uniqueness with the help of some key companies that are just as dedicated to 2-stroke heritage as we are.

The heart of this KX is what sets it apart and is not to be underestimated, as it received a complete rebuild and modification service from Tom Morgan Racing (https://www.morganracingengines.com/). Tom’s experience shines with this package, consisting of a +4mm stroke crank modification utilizing a ProX connecting rod kit, cylinder and head modifications, and a custom spec, big bore Wiseco piston. This premix-fueled beast boasts a final displacement of 327cc and is fed through Boyesen reeds and a Lectron carburetor built around the recommended jetting specs Tom supplied with this engine package. The IMS shifter will help us grab gears while the IMS Core footpegs simultaneously help us try to hang on.

What good would all that 2-stroke power be without a good drivetrain? A Japan-made ProX gold MX chain rides on a pair of ProX sprockets and is guided by a TM Designworks Factory Edition chain guide. A set of chain adjuster blocks from Bolt Motorcycle Hardware made adjusting the new chain a breeze.

The stock rims on the ’03 Kawasaki had an odd, rounded-off shape. Faster USA built a complete, new wheel set to bring some strength and a trick look to the bike. These new wheels were wrapped in fresh rubber from Maxxis, combining an ST front with an IT rear to help attack the tracks of So Cal. A set of ProX brake rotors and pads fed by a Ride Engineering front brake line were also equipped to help match braking performance with engine performance.

The frame was powder coated a cement gray color by Specialized Coatings with the goal of obtaining a different but clean look. The classic anodized bronze Pro Circuit triple clamps provide front end handling as good as they look, and a set of ODI CFT Podium bars, lock-on grips, and a clutch perch and levers from Works Connection complete the controls on this KX.

Complementing the classic Pro Circuit clamps, we even got lucky enough to come across a set of original PC pull rods during one of their cleaning sales. Matched up with all new ProX linkage and swingarm bearings and freshly rebuilt Race Tech suspension, things should be operating quite smoothly.

Decal Works did an awesome job bringing the look of this 327 build together with a custom, matte finish graphics kit mounted on a complete set of UFO plastics. Seat Concepts rebuilt the seat with new foam and custom seat cover, a major improvement over the sunbaked, crumbling piece we sent them. Literally holding everything together, Bolt Motorcycle Hardware was a lifesaver with their fastener kits pre-labeled for each specific section of the bike and engine.

A Boyesen SuperCooler water pump carries Maxima Coolanol through a set of Samco Sport radiator hoses and clamps to keep the fire-breathing 2-stroke cool. A Pro Circuit Works Pipe paired with an R-304 silencer round out the performance of this 327 build, sure to bring plenty of arm pump and nonstop smiles.

2-STROKE BEHIND THE BUILD

We didn’t want to go overboard, but we also didn’t want to cut any necessary corners, either. The crew at  Moto One did most of the wrench turning on this project, with some assistance from Pete Treadwell and the Western Powersports crew. The engine was in working order but in dire need of a rebuild, so it was completely disassembled.  CLICK THE IMAGE BELOW FOR THE COMPLETE STORY!
