Ive found a few diff recc. when its comes to jetting for these pipes but nothing mentioned about what temps there good up to. I would like to be able to run in -20F temps without having to change jetting.
Sled Now:
Stock Head Gasket(No Layers Removed)
152.5 Mains
52.5 Pilots
3 1/2 on needles
1 3/4 turns on fuel screws
Sleds lacks crisp throttle response and loads the clutchs after 70-75mph. I bought the sled last season and this is the way it was set up.
1:
150 Mains
47.5 Pilots
Raise 1/2 on the needles
1 3/4 turns out on fuel screws
2:
147.5 Mains
50 Pilots
Raise 1/2 on the needle
1 1/2 turns out on fuels screws
Friends 98 SX700 PSI Modblasters good to -40F
Middle Gasket Removed
1-150 2/3-147.5 Mains
45 Pilots
1-2 Clip Position 2/3-1 1/2 Clip Position
2 turns on fuels screws
Running stock primary and secondary springs, rollers(16mm), weights(4.5gm in each hole), RX1(51/43) helix wrapped 60deg. is the current clutch set-up.

I run 148.8 mains, 45 pilots, stock needles, and fuel screws at 2 turns out in the frigid MN winters. But I do baby it when it is way cold like -20-25
