Alan Vega said:Your slow jet looks like the right kind. I measured the one I have and dimensions are identical.
The original one is indeed a 3 piece one and the new one is 1 piece and smaller, but it fits in the thread (when screwed directly in the carb).
What is your carb ? PZ26 ?
Here is a picture of both original (upper) and ooracing one (lower) for you to see difference. The one you have should be like the lower one.
Fantastic , thanks Alan just what I needed - and seems I do have the right one - was just having a crisis of confidence late last night ! Yep , mines still on the standard PZ26 with original airbox but with a homemade down pipe (not finished yet) and a short mega .
