i never wind spring more than 80 or less than 60 ......but to run those helix will need something with alots more pressure than the stock one
 
we got the motor all back together and did some test with the new o2 sensor in a pipe .....sled is running wayyyyyyyyyyy to lean for midrange .....who think we should put back all the air box original not empty .....
 
for sure it didnt help .....midrange suppose to be around 13.5 to 14 cruising speed ..it was over 18 and guage turn n/a so need to cured that mid trouble and then will see for the main jet
 
were the needles updated when the motor switch was done? 800 carbs take different needles than 750's. What size pilots are in it?
 
pilot size are 50 ..carb came from 800 and the correct needle is there ....iddle sled running good at 14 on the air fuel ratio ..till u hit the needle setting pushing on gaz
