This is the most advanced piston available for the KLR! Gas ports for the top ring, piston lighter than others, broached slots in the wrist pin hole for improved oiling, updated second ring design for oil control. Tightened up tolerances on the ring grooves and accumulator groove to eliminate ring flutter and wear. Premium ring set. The stock ring, piston, wrist pin and circlips weigh 640 grams. This exclusive piston kit weighs 490 grams. This engine setup is much smoother than stock. The next batch with come with spiral type retainers for the wrist pin, since some people are having trouble installing the stronger aftermarket circlips. Probe Industries has done a nice video here showing how to install the spiral lock.
Oversize piston kit, fits 1996 and later KLR650. Forged, lightweight, 3mm over stock. Premium rings and wrist pin. Requires cylinder machining. This kit includes required gaskets : head gasket, base gasket, exhaust headpipe crush copper gasket, cam chan tensioner gasket. Lighter and smoother than the factory setup. If you have an oil user this is a good way to go.
Improved performance and smoother engine. Much greater difference than expected for a 41cc increase.
This kit was originally designed to be used when you wear out your 685. You can also go straight to the 692! This is a big as you should take the stock liner.
Note: We are supplying Kawasaki OEM gaskets. The head gasket is cut for the oversize bore.
IMPORTANT - these are considered racing parts, and there is no warranty. The performance and function is entirely dependent on the quality of the bore and honing, and install process.
I was extremely satisfied with the high quality products and services you provided. Each item was precisely what I expected. When I had questions, they were answered quickly and thoroughly. 3D Cycle parts is the kind of company that reminds me of a time when the customer mattered and the company went out of their way to earn their business. I have and will continue to recommend 3D Cycle Parts to others in the ADV and motorcycle community based on this experience.
