Steve Patrickson has re-vamped his website, and is now selling tuning parts such as Jha kits, HRC ignitions etc, along with a huge range of fairings to match your budget. He also has a huge stock of standard parts, e-mail him with your requirements. If you live outside the UK the prices are as shown plus shipping (i.e. no UK tax to add) http://www.sp125racing.pwp.blueyonder.co.uk/ There is also a list of second-hand parts that his customers are selling.
