250-500cc WR 300 gas mix ???

[PJBlank916]

Hey guys! I have a 2009 wr 300 and have heard many people complain and have problems with hard starting I run about 36:1 which people recommend around 50 :1 I have no trouble starting starts 3rd kick cold and first kivk warm its jetted perfect and smoke just the tight amount just a suggestion on jetting!

if it aint broke don't try to fix it
mix is a big one here, I run 50:1 but a lot of people run fatter
if it starts and runs well what are you attempting to fix
50:1 is 2% oil 32:1 is 3% oil, you add 1% more to your fuel than I do, where is that an issue

 

[PJBlank916]

I'm not trying yonfixy bike lol just giving you guys some tips on what runs good for me

IMHO thats to much oil[ if your using some good stuff] but if its already dialed to that mix and you have personal issues with it run it just remember if you switch to a leaner mix you may have to go leaner on your jetting people seem to for get jetting is an fuel/ air thing not a fuel/oil thing

Personally, I think it's technique. I've had a few friends try to start my bike and couldn't do it and then I jump on it and start it in one kick.

nothing wrong with more oil if you are set up for it. how much oil you run is directly related to how many rpms you turn how long. trail and tials bikes get away with much less oil while fast racers run no less than 40:1, usually 32:1.
40 or 50 to 1 is a good compromise with good oil. i have run 40:1 for years and have been very happy with how my engine interiors have looked and performed..
jetting is more important than anything

 

[justintendo]

way too much emphasis is put on jetting changing with oil ratio....if you do the math its quite small.

I run 35:1 Half Av gas half race gas 110 octane.

I run klotz r50 at 40:1 in all my bikes, no issues

This is going to make you crazy;- 3% oil is 50% more oil than 2%....

I run 60:1 in my 2011 WR300, Motorex Crosspower.

3 of the people I ride with do that

Right, and it would seem to me the more oil the better within reason. I'm more interested in oil injection than fuel injection on 2t. Variable injection will be sweet, lean on the bottom and rich on top.
Klotz used to be a secret of snowmobile country when I first started mixing fuel. Great stuff, I mix their SuperTech at 40:1

You run a certain premix or the type of riding you are doing, tight slow single tracks run 40/50:1 and above as you are more prone to fouling due to low speed riding with a rich oil mix, ride fast open trails and desert then run at 30-40:1 where your are riding majority at 1/2 throttle and above and the motor requires more lubrication - essentially if you ride on the stops then run a rich mixture.

With the quality of even the cheapest synthetic premixes these days, running at a baseline of 40 or 50:1 is the norm.

More oil=more power over the rpm range. That should stir the pot

 

[shawbagga]

32:1 everywhere!

 

[454x]

64:1 every where. 2 ounces per gallon is easy to remember.

-to a point- 18/1 provides max horsepower-best ring seal-
it is significant if you need every pony

 

[shawbagga]

18:1 the greenies would have kittens!

Ya rite 454x being easy to remember helps. Bring back the old days of 20:1 castrol super TT. Jus pour a whole 1L bottle in 20L jerry can
