[QUOTE="WWR, post: 674978, member: 19191"] Well, for some reason, I cant seem to get through on the phone, but keep getting this recording to leave my phone number (getting charged every time I try). So here it is: 011-81-3117-57-4774 (Japan), or email me at p-d-herr@yta.attmil.ne.jp . I have a few questions about plating. Looking on the site, there is a section for shifter karts. Having problems with my previous welded/replated cylinders recracking at the welded port bridges, I want to know if the special harder Platinized Ti plating would be better. I want these cylinders to be extremely reliable and long-lasting. And what is special about the Kart porting? Something about reliefs in the cylinder walls? What are the advantages? Also have a question about piston choice. Eric offers the RS style pistons for the CR. Do these pistons offer a power advantage since they dont have the pockets in the sides like the stock CR pistons? My stock NSR pistons have no pockets in them, and I will be going with overbore Wiseco pistons. I want the best pistons that will offer the best longevity and power advantages. Is there a Wiseco overbore RS piston that will fit that has that special coating on the top? Basically, I am building a new engine for my bike with Erics' overbore and pipes tuned for an 11,300 rpm power peak. What porting option of Erics' would be best for overall best performance? I am stuck with the stock 34mm carbs. I will be returning to the US next year (finally). Hopefully, I can attend Dirtweek this next year and bring it with me... :) [/QUOTE]
