On a recent trip to Sydney I was lucky enough to meet a guy who really knows his way around a Yamaha XJR1300. Harley Borkowski is a mechanic at the performance workshop of RB Racing. He’s a no bull kind of guy that sneers at custom builds without purpose, and he has every right to. His extensive knowledge of race engineering means he can put together a better engine than most and when it comes to customisation he’s not about to sacrifice any aspect of performance just to look good. Despite this attitude he is a strong supporter of the custom scene, lending his knowledge and advice to members of the Sydney custom scene whenever it’s required. His own heavily modified XJR1300 was on display at the Throttle Roll show this year and it was one of the stand outs for me. Having such a solid reputation means that Harley has become the go to guy for many XJR owners so when local rider Jamie Blake Crozier decided to invest in a 2006 version of Yamaha’s 1300cc ‘Sport Heritage’ muscle bike, he headed straight to Harley.
