Jetting question

[wolffo]

Hey guys happy new year!

I found the jetting tables in the clymer manual
But what adjustments do I make for:

2002 mm700
Drilled air box
Dynoport bender silencer with stock pipe

2000 mm600
Drilled airbox
Drilled stock can with stock pipe


Do I go +1 on both the pilot and the main?
Or is it +1 on both for each mod?

I ride at 8,000' to 10,000'
I was looking at the 20 degree temp column

You guys ok with babbits for oem parts?

Looks like the tm31 and tm33 carbs share the same jets, am I reading that right?

I see the #1 cyclinder jetted different from #2 & #3
Are we sticking with this?

Thanks!
Oliver

Do you mean if the jets are interchangeable or that they have the same size pilot and main jets ? Cause they run very different jet sizes.

Yes, babbits shows same part numbers

standard jetting change for a drilled airbox is +1 jet size from what you are currently running.

Pilot and main?

What about the exhaust mod?

My experience here in MN with the 700 motor was that drilling the airbox, peeling the head gasket, and drilling the can required no jetting changes from the original factory jetting. Did need to toss more weight at the clutching. Only change to the jetting was to swap the air jet to a .8 from the factory 1.0 to eliminate a lean bog when snapping the throttle open. Ran the same set up numerous times in WY and MT with normal jetting/clutching changes for the altitude and it ran like a top there too.

I don't think I have heard of an air jet

Looks like l'll be flying with one eye on this
