Nibbi racing is very good at packaging and shipping their carbs; My carb was running too rich for the given use and according to the instructions that came with the carb; their is a solution, which is to buy a slightly larger needle but it is impossible to get support from Nibbi! Unfortunately I am going to have to throw out the carburetor because they will not release the secret as to who makes the needles and they will not sell me a slightly larger needle since they will not respond to my requests for support. Major FAIL with Nibbi!!

Nibbi is a great company with a great product I bought my carburetor I bit my needle they sent me a pack of needles makes my bike run great thank you Nibbi

The quality of these needles is good as expected. I would not call this a kit though. All four of the needles are the same. I expected that as a Kit the needles would have varied in size for fine tuning your carburetor.
