I'm working on tuning my Mikuni VM-36 on my '86 Savage.
Experiencing a lot of popping and inconsistency in the 1/3 throttle range and it decelerates hard when I close the throttle. Can't keep it happy when coasting as it seems to want to speed up all the time. Snappy, but sketchy.
Since buying it, I put in the VM-36, new throttle cable from Lancer, turned the air box into a tool box and put in a pod filter, changed the petcock for the raptor, cleaned the tank and put in all new line, added a fuel filter. I also put on a new battery, igniter, coil, and solenoid.
The previous owner put a straight pipe on it, which looks good, but makes it difficult for me to know what I need for proper jetting.
After reading Lancer's "Mikuni Jets for VM and CV carbs + Tuning Info" post, I believe I need a smaller Main Jet and a larger Pilot Jet, but the question is: by how much? I've spent a lot getting it to this point, and I'd hate to buy a bunch of jets I don't need.
Currently running:
Main Jet: 310
Pilot Jet: 35
From researching, I think I may need a 144-152.5 Main and a 50-55 Pilot, but I'm not sure.
Anyone know what size
pilot and
main I should be using? (elevation 2188 ft)
