250-500cc Another premix question

so i know this topic has been beat to death and ive read alot on here, but i just bought a 2014 wr300 and cant decide if i should run 40:1 or 32:1. i would like to figure this out before i tune my lectron. thanks for any input.

-pat

I run 40:1. I broke mine in with a tank of 32:1 and had so much spooge after a short ride, oil was running out the silencer and dripping on to the swing arm!
Even at 40:1 with the keihin there seemed to be more spooge than I would expect. I run my left kickers at 24:1 with virtually no spooge.
I was supposed to be trying my new Lectron out today but it's raining here so it will have to wait until tomorrow.

Who makes that skid plate? I like the pipe protector built on to the front!

i bought the bike used with 30 hours so i dont know who makes the skid plate but i will take pics and see who makes it and let you know. I think ill stick with 40:1 and be plenty safe after i adjust my lectron correctly ...

The dealer I got it from had no idea thats why I'm worried about all of this. by the way I run klotz supertechniplate in my two strokes ( idk if that's how it's spelled)

The engine will definitely last longer at 32:1, but it must be jetted to do so. Many riders down here use 36:1.

hmmm you have a good point

Ty and I argue about this all the time. He runs 40-50:1, however, he has already had to fully rebuild both of his 2015 250 and 350's this year.

wow that a little excesive, i guess i cant go wrong to run 32:1 if im already going to mess with the carb

i also run super techniplate klotz, have forever. have also run 40:1 forever. i get good engine life out of stuff, but i dont race, just play ride but i dont take it all that easy on stuff. do you race? if i raced all season i would likely run 32:1...
dont forget ty davis is a mega fast racer.
on the other end of the spectrum i have a 88 xc250 that still has 215 psi compression that i bought as NOS. it has over 200 hours on the original bore. all its life has been 40:1, mostly klotz super tecniplate. before that golden spectro before i discovered castor.
if you have huge amounts of spooge, it likely isnt the premix, as the klotz i run has a very very high flashpoint of 460f, and i have little spooge issues, long as the exhaust isnt leaking. very little smoke, none once warm

good luck and ask around here if you need help with the lectron. they are great, love mine!

you made me change my mind. Im like you , I don't race but I'm not easy on it. I have 40:1 in here now so I'll stick with it. I'll tune my lectron tommrow tommrow since the idle screw is only a half turn out.

Thanks, It looks just like the one he made for the left kickers in the late 80's

hmm, half turn out from fully seated sounds like its rich, just guessing..
may the power of the castor be with you

I have always run some where between 32 to 35 to 1 BUT with straight 110 leaded race gas I have a 2006 Cr 125 that has more race miles then I believe any other 125 out there and it is still on the same stock cylinder and only 1 crank bearing and rod kit since 2006.
My current 2010 Husky 300 race bike went 4 years on the stock crank and is also on the same original cylinder
With race gas and the stock carb it does not spooge ever no matter where I ride it

spooge is jetting and engine condition more than anything, i believe

I mix what the owner manual says, 2% synthetic (that is 50:1) and used 3% (32:1) for the brake-in period.
Most of the guys I ride with that have 2 strokes are using far less oil than me, some 1,5% (65:1), others even 1% (100:1), the guys that runs 1% are competing in the local and national enduros and they don't have problems as it seems...

I do like going that lean with the oil and prefer to stick with 2%. But my bike is smoking a lot and sometimes I'm thinking of lowering the premix a bit.
The problem is that we do some slow enduro over here, I rarely get over 1/3 throttle and the engine gets loaded up with oil and starts to smoke... I some open sections I do twist the throttle and the smoking get better after a few accelerations.

Well, thinking it, I think I'll let it as it is and continue smoking up the guys that goes behind me hehe

Regards.

My mind is pretty much made up now, ill stay 40:1. Ill tune my lectron today since we finally have some nice weather here in jersey. Thanks for the input everyone it was much appreciated
