Hello all, Bill Blue here B&B Cycle Restoration… I am wondering how many of you would be interested in a 350 cc big bore kit for the KLX250 I am working on. I’ve already designed and ordered (4) a wet sleeve that will be made by Advanced Sleeve. The head gasket will be made out of copper, the base gasket will be the same as the one used on the 331 kit, the gaskets will be made by Cometic. The piston will have the same compression ratio as the 331 piston, 12.5:1; it will be made by JE, same that makes the the 331 piston. It will have the same static balance as the KLX 300 piston which will stop some of the buzz in the handlebars. I hope to have the (4) prototype kits in my shop in the next 4 weeks. I will put a couple months’ testing, as well as dyno testing on the kit before I will offer it for sale. At this time, I don’t know what the price will be. I will keep you posted on the progress of the kit. If any of you are interested in this kit, please contact me at B_jblue@sbcglobal.net Edit by pilot: Remove color coding by request of poster.
