Nibbi PEZ28 on 2024 CSC TT250

Hello

I can now confirm the Nibbi PEZ28 is a direct fit for the 2024 TT250. I did not have any issues with fitment. This carburetor sits almost exactly where the stock Keima sits. The throttle cable is just long enough to work. I did not have to modify anything to make it fit.

Tuning on the other hand, this is where I'm at.

Fully stock bike with emissions removed and a Nibbi PEZ28 carburetor fitted. I am in Maine and live at the beach. My elevation is less than 50' and it is summertime. Sunny day and about 85 degrees air temp.

Idle jet - 38 (factory was a 40 and too much for my stock setup)
Air screw 1 and 1/4 turn out ( factory is 1 and 1/2 )
Needle - position 3
Maine jet - 110

Idle is beautiful and strong. WOT is ok. Midrange needs adjustment.

I still can't quick throttle without it dying. I can roll on and it is fine. Only had like 45 mins to tune before having to go to work.

The max jet the carb came with is a 110. I think I either need to mess with the needle or change to a 112.

The air screw on the side is awesome.
