Cold Blooded 95

My 95 is particularly difficult to get started when it is cold, under 50 degrees or so. I sometimes have to hold in the starter button for 30 seconds to a minute before it will keep running. This is with the choke on full. I saw a mention on another thread about starting with the petcock in the PRIME position. Does this work, and do you still keep the choke on?

Unless your carbs are dry for some reason, you should not have to run from the prime position.

30 - 60 seconds is a long time to run the starter. If your engine is cold, use the full choke. Do you give it a little gas while cranking it?

You'll overheat your starter motor if you hold it more than 10-15 seconds. It should start in the first second or two unless something's wrong. Obviously that's why you're asking.
If you're getting fuel to the chamber and enough spark, unless you have a compression problem it should fire off. Check your coil voltage at the red wires on each coil and compare that to the voltage of the battery with ignition on but engine not running. If the coil red wire is much lower than battery voltage, you might need to check connections for corosion. If that voltage is good, and you're getting good spark, then you might need to replace your plugs. When I replaced mine with iridiums, my cold starting woes went away. Iridiums have a hotter spark so they fire off on a cold engine better. Plus they can create that spark with less voltage. Anyway, check some things out and let us know.

A 95 won't have the Pri(me) position on the petcock. It will have off, on, res.
Do you have a maint free battery? With more cold cranking amps, it will help your hard starting problems as well.
Way too long on the starter. Remember, if it burns out, they're about $400 new. Not cheap. You may be able to find a used on on Ebay or similar but for all you know, it could have been abused as well.

I am going to try new plugs. Mine does have a PRI, no OFF. It is really only a problem when it's cold. On warm days it fires right up.

Thanks

my vote is either plugs/wires or the battery isnt holding under load. Plugs should prolly be replaced anyway. Check wires for continuity, and battery can be load tested at about any auto parts house

Batteries certainly can be temperature sensitive. Make sure you got a good charge on it.

Someone must have switched your petcock as the 90s series bikes had the "newer" petcock without the Pri position.
As long as it functions correctly, it is not an issue though.
I tend to believe you have a battery problem or a dirty connection somewhere.
