2 stroke question?

Question

how much oil do i have to put in the petrol for it to not be rich and not stuff up the plugs in a 85cc

Answer 1

You may want to find a manual or contact the manufacturer. Different engines call for different ratios. It could be 16:1 20:1 25:1 50:1 etc.... If it is under warranty and you premix the wrong ratio they won't cover fixing.

Answer 2

use the search engine and look for an owners manual online.

just type the model of your engine

Answer 3

which 85ccm bike?

not all bikes are created alike

best is to refer to MOM

manufacturers owners manual

or

ask your friendly local dealer

or

check for your specific bike [make, model + year] online

Answer 4

50:1 is the normal ratio, that is 50 parts petrol to one part oil. Check the engine for a label or tag, it might be different depending on the service of the engine. But normal motorcycle/outboard type engines use 50:1.

Answer 5

your 85 it is recommended to be going about 35 to 40 to 1, on fully synthetic but if your still fouling plugs you may have to come up to  50 to1 . depending on how you ride it an what oil you are using.

Answer 6

it depends on your altitude but as a 2stroke rider i find 40:1 to be the best all around but my lil brothers Honda cr85 owners manual says to use 32:1 but i would still stick with 40:1
