fuel ratio mix info

hi guys running my bike on 32-1 but ssems to smoke little not so bad when hot but puffs bit when i blip the throttle just wondering what oils ect you guys are using fully synthetic ect and what mix ratios.and 95 octane fuel

Jetting is the KEY no matter what ratio you use. I still use 25:1 in my 250's , 20:1 in the 77 RM125. 32:1 works just fine, just remember to Jet for Success
Their is lot's of good reading out there on the subject so you might want to start here.

I am running 24:1 Echo two stroke oil in my 86 400 XCE. No big smoke issues. This is the recomended mix.

What jetting are you currently running in your bike? I assume you have a 38 mm round slide Mikuni fitted?

This is also a good article on castor oil from the same Super Hunky site
castor oil is "dirty"...but?.
Not sure about echo oil...

running

im running 360 main (not had good test of this yet )1.5 on air screw,
6f15 neddle and 40 pilot with 3.0 slide mod done,starts a dream 3rd fourth kick sweet but smokes a little when i blip throttle wich gets better when hot,but havent had a good chance to give it some real welly and high speed runs to try main jet properly.

Thanks, that is interesting. I will be running a 38 mm flat slide Mikuni originally from an '84 Husky CR250 on my 390. I have not had it running yet (still a few weeks away).

I have got 460 main and 45 pilot jets in the carb. The 460 was in the carb when I got it, and I have gone up from the original 40 to a 45. I beleive Pro Circuit made recommendations for the jetting on the 390 back in the day and they suggested a 480 main and 50 pilot, so I figured my starting points are pretty close. I will update you when I (hopefully) get it running.

I used to have an '84 CR250 and remember that I ran a 400 main in it. It ran sweet as a nut, so this 460 jet seems pretty big to me for a 250. Anyone got any suggestions about this?

yep

i think those pro circuit settings are for a brand new bike in probally a lot hotter climate than ours,im pretty close as i say starts real easy and ticks over no bogging but only give few short fast runs- yet to realy open her out under load so not a million miles away.so you wont go far wrong with what im at just matter trial and error really,my pilot circuit should be pretty good as i have no starting issues wich is a bonus.
