rl153 Serious Thumper Offline S40 Just right! Posts: 906 Bloomfield,CT Gender:	Prime function 03/12/10 at 17:22:12 I just started my bike for the first time in 4 months. I put it on choke to start but it took quite a few tries before it started . Is this a situation where I should have put the petcock on prime? Thanks.

Just to clarify a touch,....there is no difference tween prime, run, or reserve, as far as the running of the bike.

Run = gas will flow from the tank only when the engine is being cranked and/or running, but will drain the tank only down to the reserve amount

Prime = gas will flow from tank and have gravity pressure to the carb all the time, but will drain the tank only down to the reserve amount ??

Reserve = gas will flow till the tank is completely empty as long as the engine is being cranked or running

ps: Did I say that right I hope ? Shocked

On edit,.....I stand corrected,
"prime" will drain the tank dry

Actually from what I understand Prime will drain past reserve. I am not certain on this but I believe it has been posted before about that issue.

Posts: 28663 Tucson Az Gender:	Re: Prime function Reply #10 - 03/14/10 at 08:15:05 When the bike has been sitting more than a week, or to drain the tank to work on the bike, or when you have done carb work and need to refill the float bowls... That's it...

Run has a taller pickup, so, it runs out of gas while thers still some in the tank. The difference between prime & reserve is that reserve is running thru the vac operated part of the petcock. Prime delivers fuel to the carb, even if the engine isnt running.

You only need to use prime if the bikes been sitting long enough that you wonder if fuel had evaportaed out of the bowl. Prime, well, it Primes the carb.
