[oneroom42]

does anybody run 40:1 ratio. i was told the blaster will run better and cooler but i dont want to try unless i get some other opinions.I:I

 

[ron89]

i run 40:1 in my rm and blaster, they are jetted a little rich so it dont really make a diff lol.. if your stock then just stick with 32:1..

 

[oneroom42]

what size jet do you have in the blaster?

 

[ron89]

i have a 280 main with the air box lid on,

 

[oneroom42]

do you know what size jet is stock

 

[stephen12091985]

i also run 40:1

 

[blasterman87]

230 main is stock

 

[Mrbrocco]

correct ^ so if you remove your airbox lid and run a 40:1 you should be fine if not bump to the next 2

 

[blasterman87]

Removing the airbox lid you should put in a bigger main jet

i run 32:1 Too, 40:1 is a little Lean for me.

 

[blasterman87]

yeah i agree... with 32:1 your crank bearings will last a little longer

what does the oil injector mix at?, because mine still works. im just waiting for that to go so i have an excuse to do a complete engine rebuild

 

[blasterman87]

30:1 I believe

 

[tjsdaname]

[stnditup2]

32:1 for me and i would get rid of that oil injection

I run 42:1 with Golden Spectro Synthetic/Petroleum Blend and VP fuel with no problems. Spectro is designed to run up to 64:1. Basically its one 12oz bottle to 4 gallons of fuel.

so with my list of mods would it be better to run 32 or 40

50:1 on stock engine with K&N filter closed moded airbox. Amsoil interceptor.

Running anything richer than 40:1 with a good fully synthetic oil is just wasting oil.

Jet size doesnt really effect your oil/fuel mixture. Your main jet controls your air/fuel mixture.
