(E8) Hellcat Raptor 125cc Nibbi Carb side by side comparison Keihin Mikuni. Tuning jetting

4 years ago

26mm Nibbi carb comparison and tuning on the Grom clone Hellcat 125. It is way lager all the way around for performance, but is it needed on what I have now? Seems the Nibbi is a bit too much for my configuration but did as good as the Mikuni. I also test which jets will fit in the Nibbi carb

I ended up with a 120 main! After multiple test drives and adjustments.

Keihin jets will fit the Nibi

It goes pretty good for a 125cc bike (55 mph after tune), suspension is nice, braking is good. 0-50 mph in 19 seconds

Frame bolts: The ones on a bike or metric but 5/16-18 or 24 (preferred) 5" long will work. I'd get grade 8, Grade 5 minimum. (https://ebay.to/2zdtG8a Grade 8) (https://ebay.to/2L5sCWq Grade 5)

I think it would be an awesome around town or city bike. Just like the clone it is not very fast
