Riempies has become so used to the perfectly designed power delivery of PZ490 thanks to Neels the 2T magic wizard specifications for the Roof that Riempies craves more “excitement” from the already amazing bike he’s got! In Afrikaans we’d say “wat ‘n vraat!” Translated it means Riempies is a glutton….
In any case, we have spare barrel castings and had one machined ready for Nikasil application to use in the square engine we’re building to develop the external starter for PZ500. What if we were to whisper some of Neel’s magic into the PZ490 ports, make a new expansion box (thanks Neels) and build a new spec engine for Riempies and let’s call it PZ495! Yup, that’s just what we’re going to do, build a 2nd version of PZ490 because we can!
PZ490 goes on the dyno in the next days (thanks Con Burger from Hyper Dyno who’s a staunch member of this group for offering the dyno opportunity!) to make sure we get the figures Neels intended. The next step is Neels will generate new porting and expansion box design with his Vannik software and next weekend when I’m in Pretoria to pack my crate, I will port the new barrel to Neels’ specification before it goes for Nikasil coating, yeah baby! Don’t you just love a plan!
