Today (Feb 23,2016) I should get my NEW OEM decompression solenoid and then I will know how far it should stick out when at rest and when energized.
The Clymers' Yamaha workshop manual is very useless on information on this part.
Someone made a back room deal.
Any way I will find out and report back to the forum members.
The solenoid is 10 years old on my 2006 model.
The new decompression solenoid arrived!!!
The solenoid push rod only sticks out about 1/32 of an inch. On the new OEM solenoid.
If you pull lightly on the solenoid it does resist immediately.
The solenoid spoon is right against the solenoid push rod.
Getting the screws loose was a little difficult because they had been installed with red locktite?
I put the new solenoid on and it tried to start on the first attempt with no help.
It was very low on gas and I think I gave it too much throttle it backfired.
I waited a few minutes then it started with the choke off.
It was about 65ºF today.
So it looks like it it was ridden a little it will be ok.
Brand new battery too with 320 cranking amps.
What I wonder is why the battery gets so low so fast.
I have a new starter too.
I have worked on motorcycles since I was 16 years old.
I am 66 now and this Yamaha Roadstar is very weak on starting.
The only thing I have not done is to change the negative battery cable.
I think I will remove it and test its resistance.
The positive battery cable is brand new 4GA> wire.
The positive battery cable is not any longer than most other motorcycle battery cables.
One more thing.....There are two plastic washers on the solenoid mount and it looks like it would be easy to put slightly thicker washers on and space the solenoid out just a little bit.
When you attempt to start the bike the decompression solenoid is being activated at the same time as the starter. A big drain. So when you pull the spoon /lever thing the battery gets some help.
Brand new decompression solenoid.
