I have read on other posts. You have suggested jetting down to 142.5 across the board and moving down to 2.5 on the needles safely on the 700SXR's and 700MM's. I have an 02'7MM,stock pipe w/bender can, also have removed 1 layer from head gasket. will this run safely between 0-1500 ft., temps -10 to +35 deg. . I have stock 145-143.5-143.5 jets in now. Sorry for the repeat question, just had to make sure before I do it. Thanks, Soc
 

You got lotsa room at those specs..even with a layer removed from the head gasket!
 
Turk,Forgot to ask about....

Is this jetting safe with oxygenated fuel ?? Also, what is the reasoning for Yamaha running one size larger on #1 cylinder verses #2 and #3. Thanks, SOC

ps.water super, it affects your mid range. use search and type in needles!
 
SockeyeRun,

Just went to the same setup on my 99 MM. Guys at Anch Yamaha said that setup is good to about -10 at Big Lake area, good to about -20 at Petersville. Much colder than that and they said don't use full throttle much. I forgot to ask about oxy-fuel though.
