Thanks Bill,
You have put my mind at rest at little now. I think I was getting a case
of Triumph Hyperchondria! I drove to work this morning and didn't take
as much notice of the noises (put the radio on) and she seemed fine! I
think I have got so paranoid of late that I automatically assume that any
little noise is very serious! It may take a while till I trust Saskia to
be reliable. I just keep thinking that all the pain and aggravation will
seem so worthwhile in summer, cruising the beautiful English countryside
with the top down, the wind in my hair and a beautiful girl by my side...
The jets have thin red ends to them and not discs so that sounds like I
have the non-waxstat type. Probably wear elsewhere in the carbs then.
I think I'll get a carb overhaul kit and may do them myself, and a new
steering rack, tie rod ends and knuckle joint to sort the steering out if
their is nothing badly wrong with the engine that can't wait till next
month's pay check
cheers all,
John
