what ratio should i run?

[honda man]

Ive got a 1986 trx 250r bored .30 over with a k&n filter, paulturner pipe and fmf Q series silencer. my main jet is a 158. everybody around here tells me to run 32:1 but I think thats too fat. any suggestions. I ride mostly at sea level.

The ratio has really nothing to do with it running fat, what makes it run fat or lean is the air/fuel mixture witch is in your jetting. I'd run 32-1, it's safe and i have been running it for over 10 yrs with no problems.

right on, thanks, thats what ive been running, just seems to smoke alot.

As far as it smoken alot, does the bike run good?, does it get loaded up if you let it sit and idle for a while? do you foul plugs often? if you have any of these problems your jetting could be a little on the rich side...if you dont have any of these problems then let it be...it's a 2 stroke...it's supposed to smoke...

40:1 is fine also. thats what I run in my R with klots R50 or benol.

im as sea level as it gets...
i reccomend that you run 32:1

i recomend 32:1, ive never use any other ratio than that, its more safe.

i would say us any ratio as long as you are burning blue and dont mind going throw plugs. i do 40-1 works

I run 32:1 on my steel sleeves and 20:1 on anything nickaseled

I run 110 octane 20:1 with amsoil dominator in my 300r and my 250r.
