Hi, I'm new to the forum.

It's a 1995 F2 done 27k miles, runs perfect otherwise.

Problem starts when the bike has not been started for a week or two and is more acute in winter temps.
Put on full choke, press starter, engine spins but not a peep, doesn't even try. Solution is to warm up the engine with a fan heater for a couple of hours then she will start in an instant.

So, it's either fuel or spark. I know the battery is not perfect but I trickle charge it on a regular basis. Usually reads 12.5/6v. When ignition is on this falls to 11.6 after 10 secs. I'm not sure how susceptible these models are to slightly lower voltages as regards starting.

Fuel- maybe it's the e10 fuel that is in the tank that's not helping?
 
Durango i am in chesterfield and have to give my 1979 750 FZ some warm hairdryer in the air box , once started she is fine the next day if i leave her for a week i get the same problem, i think they they have to be perfectly set up 100% with everything
