We’ve been fabricating brake hoses (“lines”) in braided stainless steel covered teflon for more than twenty years, mostly for BMW motorcycles. 

These beautiful forged pistons are machined to my specification.  They are lighter than stock, and are available in various compression ratios.   They use dual tru-arc snap-rings for wristpin retention and easy installation

I’ve beeen doing cylinder head work for over forty years.  BMW heads have given us some “interesting” problems, frequently wearing faster than they should.  Lengthy experimentation led me to finding someone who would provide a valve guide that would meet my specifications.  These guides are a special bronze alloy that resists wear and seizure.
