Hi Jim I live approx 4 miles from St James Street in Glos. I know exactly where it is because ANTIG have their workshops there. Have you heard of those guys? Also, why do you ask about St James Street?? The 400F parts I am seeking are the main swingarm bolt (1W4-22141-00-00) and the engine mount spacer (2X5-21459-00-00). If you have these lurking about I would be most appreciative. I am trying to get the old bolt out and its proving to be a real swine. I am going to (reluctantly) try heat on it tomorrow and failiing that sticking the grinder through it. Why Yamaha did not put a grease nipple in this area baffles me. Thanks for the carb info. I will buy a new one I think. cheers for now Ruairi |

Hey Jim Got the pictures of your Antig. Needs a bit of work eh?? Its a classic though. How many of those are there in OZ I wonder. What help do you need from me regarding visiting them. They are a traditional style proper engineers that produce what I can only state are the finest standards. They resleeved a BSA C15 for me and what a superb job. If you need me to do anything just ask and I will see what I can do. cheers Ruairi |
