Default premix

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

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?

That would be 50 to 1 or 2% so you're doing it right.

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.
