I have a cateye fs509. I bought it used. On the bike, there is a sticker that says to run an oil mixture of 25:1. I run 25:1 through the bike, and oil leaks out the exhaust pipe. A fairly large amount of oil has trickled out. My friend that I bought it from also ran one tank of 50:1 mixture through it, and it also leaked with that mixture. Am I running too much oil in this bike? What is the proper mixture for the cateye fs509?

25.1 is for break in, 40 to 50 to 1 is what most of us use.

My avatar A2 cag has a 16:1, FC crank, modded 4 port cyld, and more, it spits black stuff out the back, and a boost bottle makes it even worst,lol., can't walk behind it, have to wipe the rear of the bike down all the time, the more compression the more spit. The rings have not fully seated yet either.
