So I started a restomod of a CL90 that I swapped in a YX140 (Piranha) with a VM26 carb.
Im trying to get the bike running right and there is some serious jetting issues.
My current setting:
P: 30
M: 165
AS: 2.5 - 3.5 out
N: middle
I have tried the following jetting and im running out of ideas on what direction to go.
1. Setting the VM26 with 2 - 2.5 turns out the bike runs but hunts for idle.
2. Raising the needle up the bike idles a little better but smokes once the bike is shut the exhaust smokes
3. Lowering the needle 1 clip the carb back fires, same thing happens with the stock mid needle location 2.25 turns out for the air screw starting with 1/4 choke.
4. Holding the throttle open a bit and trying to get going in 1st the bike bucks and then surges over and over.
Any help would be great
