ON A 700 SX MOTOR FOR 660 ICE DRAGS MAIN JETS ?. I BELIEVE IT HAS 152.5 ACROSS BOARD. GUYS BRINGING SLED OVER TONIGHT. GO UP SLIGHTLY, STAY, OR DROP. THIS IS FULL RACE MOTOR ON 110 RACE GAS. 3:16 (yammie tony)

Does it have a High compression head, or shaved heads? If so, I'd say stay around 152.5 to 155 at 20*F. Then go leaner if needed after the initial run. Rather see it run a lil rich then to have to put pistons in it.

tony:
that's a loaded question. what is comp. ratio/cranking pressure/squish? does it have case porting, reeds, stock trail pipes or cut?
for 660' w/ normal bender trail porting & bender pipes & fresh 110 octane fuel 152.5 would be too rich. probably closer to 145's.

BOB, I BELIEVE THIS SLED WAS BUILT BY JUSTIN. SO ITS HAS ALL THE GOODIES. I DON,T BELIEVE COMPRESSION THROUGH THE ROOF BUTS ITS EASY 160. IT ALSO HAS THE PIPES WE TALKED ABOUT THIS FALL. I LIKE TO DROP IT ALSO BUT SOMEBODY ALREADY HAD '' SAFE '' JETS IN IT. THIS SLED REALLY NEEDS TO BE FAT AND HAPPY, OWNER REAL HARD ON IT. THANKS. 3:16 (yammie tony)
