1995 Magna Trouble

[Darrin]

Hello Everyone,
 I have some kinda wierd problem with my 1995 Magna, I have already replaced the Ignition Pickup, and the ICM, i went with the Dyna Performance ICM module. Anyway back to topic the bikes runs great for
short distance rideing.. I drive it to work almost everyday with the gas prices the way they are, anyway every since i have had the Bike the same
thing has happened. When i ride for an hour solid or more depending on how long the gas lasts, i stop and gas up .. then when i start rideing again
it just quits, unless i give it more than half throttle. Today i spent some time while i was in north Carolina rideing back into east tennessee to try and figure it out .... here is what i know .. then vent hose is not pinched or stopped up,ICM good, Plugs Good.. i have vacum going to the shut off and it seems to work..., and here is the funny part .. as long as the bike is in sum kinda pull ( going uphill, or accelerateing it runs .. but while coasting it does not run ) .. man this bike is driveing me crazy .. any ideas would be greatly appreciated....

Darrin sounds like you are loosing vacuum to the auto fuel shut off diaphragm or at least limited vacuum at idle.  
Try pulling the air-box and cleaning thoroughly and checking the vacuum lines.  If this does not help then I would suggest using a miti-mini vac to put a vacuum on the auto shut off diaphragm to see if it has a hole or such in it.
Sounds like that it maybe the culprit.

Thanks, I will try that tomorrow the cleaning begins ...

Then Bypass that diaphram and happy riding. Expensive part and really isnt needed. Just make sure you shut the fuel valve off when not riding, I did this to my 1983 honda cb1000C and my bike runs great. The part cost is over a hundred dollars. go down to the auto parts store and get some fuel hose and by-pass then just plug off the vacuum source.
