British Bikes / T140 needle setting
« on: August 02, 2007, 09:23:42 PM »
Can anyone help with verifying the correct needle position on my 1976 T140V US export. Workshop manual says correct needle position is 1 but I don't know if this means top or bottom notch - there are 3 notches in the needles. Bike is fitted with original twin Amal MkI carbs. I am using in UK so no altitude adjustments required ( well at least I don't think the Peak District qualifies as high altitude!)
Also the spring clips that hold the needles in place are split. Should they be or do I need to replace them? This might explain why they moved in the first place but I seem to remember buying them new a few years ago and think they came like that.

Regards,

Dave

Thanks again. That's the way I figured it too and it's running a lot better than it was.  I have just read your correspondance with ChrisT140 which seems to answer all these carb related matters.

Regards,

Dave.

Thanks TBS. I found a problem with the needles in the carburattors which may explain some of my problems. The spring clips that hold the needles in position had come adrift. Do you know what is the correct position? My workshop manual says position 1 but I don't know if this means locate the clip in the top notch or bottom notch? Also the clips appear to be broken - do you know if they should be in one piece or is there supposed to be a split in them where they grip the needle?

Regards,

Dave.

Does anyone have any advice on using lead free in T140's? I have been running my '76 Bonneville on lead-free for some years now although at very low mileage. I can't decide whether the performance has suffered or whether it is due to comparing it with my TT600! I wondered whether I should have altered the timing for the change in fuel.
