Whats the fuel-oil mix ratio on a 1994 Honda CR125?

Answer 1

I usually work it at about 50:1 ratio. That's 50 parts petrol to one part 2 stroke oil. You might find it useful to purchase a small mixing cup (like a Ratio Rite). It'll let you mix easily no matter how much fuel you have.

if you were smart you would run 40:1 and have your bike last longer.

-Most manufacturers recommend 32:1 ratio as this provides the best lubrication and will prolong the life of your piston and cylinder. If you run too lean (ie-50:1, you will go through pistons and cylinders much quicker) The only problem with running too much oil is you can foul plugs, so it will take a little trial and error as each bike is a little different.

I personally run about 38:1 (according to the ratio rite cup) on my Suzuki RM 125. Keep in mind, if you run less oil, you are also making your bike run richer, so you may have to adjust your carburetor jet settings to compensate for it. Your best bet is to call your local Honda dealer and ask them the correct ratio for the bike, better yet, get the repair manual. (and definitely don't run 50:1 unless you like frying your piston)
