Was filling the bike up today with the jerry can that i had full of fuel (5L) was putting my silkolene premix stuff into it when my mate said hang on :confused:

My mate said im doing it all wrong im premixing to much with the 5L fuel i was putting in

5L fuel + 100ML silkolene premix, Correct?

I was also told this was the correct level of mixing from the guy i got the bike from.

Could someone confirm that im correct? :)
 
When I bought my LTR jet kit Les advised me to run 32:1. Against his advice I have ran 40:1 since the bike was new. Same in the kids bike.
 
I run 45:1. Used to run 40:1 which always left a small amount of spooge at the end of the silencer. 45:1 has always left my silencer clean.
 
I run 38:1.

Why? More oil = better ring sealing and less wear.

My 2 data points...

Top ring end gap increased 0.006" in 91 hours at 50:1

Top ring end gap increased 0.001" in 49 hours at 38:1

This data was with AmsOil Interceptor. Your mileage may vary.

See premix tables here:
http://www.gasgasrider.org/forum/showthread.php?t=182
It lists the amount of gas in first columns, then the amount of oil in the last columns.

5 liters is approx. 1.25 gallons... so 100 milliliters is right as mentioned previously.

The link above gives premix for a variety of ratios.
 
I run 44:1 amsoil interceptor. why 44:1 and not 50:1 like gasgas says? 50:1 seems like too high of a ratio, and that extra oil keeps me from thinking whether or not this thing is going to blow up if I hold it wide open going up a long, steep hill.:D
 
Easiest, no-brainer is 43:1. This equates to three oz. of oil per gallon of gas. Couldn't be simpler. But then again, i am quite simple.
 
Interceptor is formulated to keep power valves clean which seems to work. In all honesty I just trail ride and I could probably get by with the same ratio I use in my trials bike which is 80:1 without causing harm.

Dominator supposedly is for more severe use like racing.

Same here. I'm a trail rider and turkey run guy. I'll pick up some Interceptor.

Thanks

32 to 1 here. I would rather buy more oil than buy more engine parts.

Just wondering what you mean Steve?
I have gone from 32:1 in MTX (castrol), to 50:1 Motul 800.... jetted accordingly .
I did this as I thought the fuel air mixture was out due to there being more oil , less fuel etc etc.
The bike runs great and is recommended to run at 50:1.
My question is" who is right"?
I know it comes back to jetting correctly in the long run but as I found out twice, more oil does not necessarliy mean less heartache.
Correct me if I am wrong.
Cheers Mark:confused: :confused:
