Just tested my top speed with my motorcycle carburetor swap and I got between 120-130 KM/H. The carburetor I used was a NIBBI clone 34mm 250cc. The jets used were (main jet #150 and pilot jet #40). With these jets I don't have any issues with the idling and the acceleration. Here are the parts, videos of the installation and speed test: Caburetor Motorcycle 250cc https://a.co/d/eNHAygz Choke Cable https://a.co/d/4iJoteV WIX Filter https://a.co/d/f7RHX97 Flange https://www.ebay.com/itm/1444671853...KuXgxu1SXu&var=&widget_ver=artemis&media=COPY 20 Pieces Carburetor Main Jet Kit https://a.co/d/dnzupsD Bike Shifter Cable Housing https://a.co/d/4zYMxSc Dorman 03336 https://a.co/d/4vSqjDO Installation video I hope this post could help SOMEONE!!!!
