We have had some experience sleeving the EBR cylinders. We cannot comment on the motor as a package, as were not experienced with the internal motor components or drive train. But, we have had the opportunity to both re-sleeve the 1190’s to its original standard bore, and we were tasked to create a big bore sleeve design for the cylinders.
We had removed the original cylinder liner for our more performance based MOLY2000 centrifugally spun-cast ductile iron cylinder sleeve liners. Our MOLY2000 is made with greater lubricity, tensile strength, and elongation than is found is production based cylinder sleeve liners. The sleeves are laced with chromium, and molybdenum providing a better surface finish. That will also give you assurance of a better seated ring for the longevity. The ductile will also stay rounder, also acting as a added assurance to combat blow-by.
Ultimately, our goal was simply to provide a better running cylinder for our customer. This was specifically for the standard bore 1190. There is very little history to point to on these cylinder sleeve jobs as those bike are rarity or boutique type ride. We haven’t seen the numbers anywhere close to what we’ve seen in the Japanese street bikes, or Harley’s requiring the same assurance. We’ve had great success in simple street builds, or drag bikes like Eddie Kraiwec or Larry McBride have succeeded on. We’re confident our MOLY2000 material will provide the confidence you want on your power plant. Cost on a re-sleeve is usually $350 per hole or $700 for the twin. If there are repeatable type jobs, the numbers will easily drive down the costs per unit.
The big bore was asked by a EBR patron. The bigger bore was in the design process but the customer backed off the big bore prior to completion. His hope was to take the 1190 out to a 1340. But, project stalled. Based on our findings, we think it could’ve been done. At his point, all we have is theory, and no concrete evidence. Should you consider the big bore, we’d approximate the cost at around $900 to start. Again, if the numbers grow, the cost would reduce. Let me know if you have any other questions.
