OK so i fired the bike up its a 421 cub that i converted to alky, and i am getting liquid out of the pipes.. every time i rev the engine up it blows out some oily liquid,, i am pretty sure that its not coolant because when i was running the alky it came out the color of the pre mix and when i purged the line to store it it came out black from the gas any ideas?

Happens to the best of us. When you switch to alcohol carbs. You will need to "clear" out the fuel system before you run it. When you pull up to pre-stage, drop it into neutral and give it 4-5 good revs. This is when you will see a lot of excess fuel coming out of the pipes. You'll be able to hear the difference in sound that the engine makes once the system is clear.

 

This is of course assuming that it is a drag bike.

 

When you purge, same thing will happen. Your purge gas should not hold enough octane to make the motor run. That is why most people have to keep revving on the throttle to keep the motor running while purging. A LOT of unburned purge gas will come out of the pipes.

 

Note; Do not purge near anything of value. Hahaha.
