There is nothing in this for me, just wanted to highlight a bit of success that I had with some coils and caps that I found on eBay. I went for NSR125 coils and NGK silcone caps. The whole lot came to about £35 and the bike is now running sweet without a hint of missfire. If you think you need new coils this may be the way to go. The coil needs the mounting lug cutting off with a junior hacksaw, but after that they fit perfectly in the standard rubbers.
Good luck.
