I recently acquired a Wossner Piston Kit with a second hand KLR650, in NSW Australia. As my year model didn't seem to align with the applicable models the Kit was designed for, and not being able to find answers in any of the KLR Forums, I penned an email to Wossner, and didn't really expect an answer, as the product is discontinued, and I wasn't the person who purchased the piston kit. Not only did I get a detailed, positive reply, but despite it being 10pm on a Saturday night in Australia, the response was in my inbox before I checked my emails on Sunday morning. Hoping I'll be able to return to sing the praises of the product, after I get it installed over the next few days. Thanks Wossner.
