JL - Excuse my ignorance (but I've yet to get my hands on a RZ/RD350), by "hop up spool" are you referring to the cable operated drum that opens & closes the power valve (& presumably there's only one per engine)
With regard to power valves, are these in production yet, & if so, what's the cost?

Hi Jim I made one set for my own bike thats it.
Right now everything is on hold till I finish and ship out the RZ CDIs.
Its also slowlly dawning on me that all these products are no high volume sale products and Im just wasting my time developing them.
