Nibbi PEZ28 on 2024 CSC TT250

Bill Hilly · 08-28-2024, 06:05 PM

This is a follow up to my post earlier today. The Nibbi PEZ is not a PZ30 clone, but it is made as a slightly more direct replacement for the PZ30. Basically the PE28FL, and the PEZ look the same, but the PEZ has about 45-46 mm O.D. breather side, and the PE28FL has about a 49mm. I think, (but don't know for sure) the PEZ has a different needle. I don't have a PE28FL around anymore to compare with, BUT I have noticed the needle on my PEZ is very sharp, and thin , and has no taper for about the first 3/4" or so. Any jet bigger than a 115 slides way down the needle. A 120 slides right down it . I realize that's probably why I had to lower the needle so far when I had my hotter motor , and was running a larger main. I don't think the needle in the PEZ is going to be ideal with larger jetting. These are pictures of the needle, and the needle with a 120 main on it. A 115 will not slide over it.http://
