Thanks again, I've already found a new air box lid, I hope it comes with the seal, but probably not.
the JT in JTX are the initials of some guy who developed it, apparently, it's unbelievable how much irrelevant crap you have to wade through to find just the right parts for the right year,
I have over 8000 meters of mainly terraced land and a friend with farm land that can't be farmed in places, lots of gullys from flash floods it's also all dirt roads around me. It's a very very long time since I have been on a proper trials bike, Yamaha TY125 (tiny)definitely before 1980, I did have a striped down modified DT175 that I absolutely loved and used every week, unfortunately they built houses on the farm I used to play on so I got rid.
oh, another thing, I'm considering having to forks re chromed, I used a place in England over the summer, they said three weeks and the took 7, I don't mind 7 but please people if it's going to be 7 for gods sake say so, they were for a customer, I'm going to have a chat with a Spanish mechanic I know and see if I can get them done in Spain, by the way I'm semi retired and work over the summer in England as a motorbike machanic in a small town, so I'm used to working on crap. Thanks muchly, it's been interesting and informative chatting with you. Rob
