so i recently got a CLYMER manual from ebay(yeah)
for my bike an 81 honda cr80, it says that i should use a 20/1 fuel mix, im using a 32/1 fuel mix right now i got from the forum, what should i go by.
CLYMER manual are wrong it should be 32:1 fuel even frist CR80 that come out in 1979 was 32:1 if I recall rigth on tank sticker.
How ever if this is a new motor rebuild I would do the frist tank of gas at 20:1 and change out the spark plug with new one after first tank.
20:1 is was best use in some much old stuff like chain saw, weed eater, boat motor and older scooters.
