This jetting seem right?

[Quinc]

Picked up a non-running blaster and finally got around to looking at the jetting:
Mod bpipe
R&D head
62t/61x bored to 84mm
stock porting
dual OEM 44's
R&D intake
Carbon Reeds
stock ignition.

The jetting is:
115 Pilot
117.5 Main
29psi Pop off

Compared to the FP manual it seems off by a lot?
70 Pilot
140 Main
55psi pop off

FP jetting is for stock 38mm carbs

Look through the carb database and find a similar setup

that sounds about right but usually the main is a bit smaller than the pilot. does not running mean blown up or what...........

original owner, told me the start switch stopped working 6 years ago so he bought a couch.. Minus the rust the engine was in good shape.

if it was tuned when it was put away, its probably still tuned/close

There are so many jetting configurations that can be run.......... It is all about the combo of jet size and N.S. size.

Its close but you are losing torque by running a small low and such a high pop off
