Yep you got it.......pain to change, and a pain to find a replacement. Actually with a long enough screwdriver it isnt too bad. Brian Link to comment Share on other sites More sharing options...
Yammer Dan Posted May 21, 2012 Share #3 Posted May 21, 2012 Sounds like you need to clean connections. Link to comment Share on other sites More sharing options...

Brian I got one from my local Yamaha dealer for less than the cost from PartShark after factoring in the shipping costs. Don't forget to get a new cover gasket. I think Yammer Dan's suggestion is more likely though. Probably a good idea to check all your electrical connections before spending your money.

I tried local stealer, partshark and all the usual suspects before I finally found one. Brian Link to comment Share on other sites More sharing options...
Venturous Randy Posted May 21, 2012 Share #6 Posted May 21, 2012 I don't think it is the neutral sensor as pulling in the clutch should over ride it. At least that is the way I am thinking this morning. RandyA Link to comment Share on other sites More sharing options...
flyingyaks Posted May 21, 2012 Author Share #7 Posted May 21, 2012 OK...I will try cleaning the connections first....do I have to take the plastic cover off and clean behind it or just the outside (was fairly oily)...cleaned it this morning and will try it later today...but this time the bike will be home when hot!....I tried the clutch lever idea but forgot to raise the kickstand too....Thanks guys......also if this needs changed,do I have to drain the oil first?

mbrood Posted May 21, 2012 Share #8 Posted May 21, 2012 As was mentioned... the neutral switch won't keep the bike from starting... it just changes the requirements... using the clutch when hot should bypass the kickstand/neutral switch combo. If she still has a problem then it's outside that path... either solenoid or starter... did you hear any clicking of the starter solenoid ?

flyingyaks Posted May 21, 2012 Author Share #9 Posted May 21, 2012 Thank you for the replys...when hot the neutral light is off and it won't start...it's like there isn't a battery installed...as soon as it cools the neutral light comes on and it starts right up...pulling the clutch with the kickstand up does nothing either....starter seems ok...no clicking..possibly a little slow,but this bike starts immediately(maybe 1/2 -1 crank)...I did notice while waiting for it to cool,,the bike is on the sidestand and when the neutral light comes on if I straighten it up to go,the light goes out until I put it on the sidestand again,eventually (15-20 min.) it will stay on when the bike is vertical and I can drive away...seems to me there must be an expansion on something to ground out?

dingy Posted May 21, 2012 Share #10 Posted May 21, 2012 Possible problem with the side stand switch, due to change in symptoms when weight is off side stand. You will have to pull the neutral switch to clean contacts. On the few I have seen, the brass tip that is on the gear shift cam is also been worn down a lot. Attached a couple of pictures of places you may visit in this journey. 1st is switch towards bottom center of picture. 2nd is view of location on mostly bare block, left center. 3rd is pin that contacts pads on switch on shift cam out of block. 4th is business side of switch, there is one unused contact, maybe there was a six speed on the drawing board at one time. 5th is a view of switch as it will look when middle drive cover removed. I put RTV on it to protect it, your cable will be black. Gary Link to comment Share on other sites More sharing options...

Loose battery connection, even though it 'feels' tight. Take plus and neg apart, sand battery lugs and wire terminals until shiny, reattach and retighten Link to comment Share on other sites More sharing options...

That's what mine did too. Replacing the switch fixed the problem. When I did the job I laid the bike over onto the crash guards, had to prop the front up a bit so it would sit level. Did not have to drain the oil. Followed the directions Dingy gave, thanks Dingy. Link to comment Share on other sites More sharing options...
flyingyaks Posted June 5, 2012 Author Share #13 Posted June 5, 2012 OK folks...I installed a new solenoid,cleaned every connection I could find,applied dialectric grease to all the connections...dicovered the clutch switch was sticking and resolved that issue...it will now start hot if I use the clutch... when hot the N disappears,a few minutes later, the green light will go off (until it cools down)...when then green indicator light goes off it will not start unless I pull in the clutch...something is getting hot and causing this problem(neutral indicator switch?) it seems I've ruled out the starter and solenoid...thanks for all the help Link to comment Share on other sites More sharing options...
gscbertrand Posted June 5, 2012 Share #14 Posted June 5, 2012 What shape is your fuse holder in? When you say "like no battery" have you tried the horn or brake lights? Link to comment Share on other sites More sharing options...
flyingyaks Posted June 5, 2012 Author Share #15 Posted June 5, 2012 lights are on...just dim when I hit the starter....don't remember trying the horn Link to comment Share on other sites More sharing options...
friesman Posted June 5, 2012 Share #16 Posted June 5, 2012 MY 85 Has the weirdest issue, about twice a year it will not start when hot. the rest of the time its got lots of juice and fires right away. But those rare times it just does a click and the dash lights dim and the headlight goes off like its sposed to. Well, one time i got frustrated and just started pushing buttons while i was holding the start button and when the horn sounded it must have completed a circuit somewhere and the bike fired instantly. I dont know why the horn thing works on my bike, but it does...Ive checked grounds and everything I can think of. It happens so rarely that I will just deal with it until it gets worse. So try your horn when holding the starter....see if it completes your circuit or makes a ground work for you....who knows? Brian Link to comment Share on other sites More sharing options...
jiobst Posted June 25, 2012 Share #17 Posted June 25, 2012 I just got an 89 Royal and the Neutral light and Gear Indicator all work when the bike is cold and a short ride. HOWEVER… one it gets hot I see the gear indicator for 3 – 4 – 5 but not for 1 or 2 I can select those gears but the gear indicator on the dash is blank. Also when hot I cannot get neutral and as a result the light never comes on. The starter will not engage unless the bike thinks it is in neutral hot or cold so I assume I also have an issue with the cutch engaged switch. As a result I need to either never turn it off or bump start it when it is hot. This is a challenge to get gas since I don’t want to leave it running or wait for it to cool off at every gas stop. Never had these problems with my previous 83 venture. Link to comment Share on other sites More sharing options...
camos Posted June 26, 2012 Share #18 Posted June 26, 2012 This is a classic example of a faulty neutral switch. There may also be issues with the clutch switch and side stand switch. If it will start in gear with the side stand up and the clutch pulled in then likely it is only the neutral switch has a problem. Unless the neutral switch is actually borken you will need the contact pin and spring, an o-ring that goes around the switch and a middle gear gasket. Not very expensive, probably about $10.

jiobst Posted June 27, 2012 Share #19 Posted June 27, 2012 I checked and both hot and cold the starter only works if the neutral light is on. If in gear no started clutch in or out side stand up or down, how do I check the clutch and side stand switches? Link to comment Share on other sites More sharing options...
flyingyaks Posted July 16, 2012 Author Share #20 Posted July 16, 2012 Found the probem!!! saved the neutral indicator switch for last..the problem was the spring and brass pin....with gasket a $10 fix...the spring was pretty sacked out maybe 30% of the new one ,pin was fair but showed wear...I cleaned the switch as Mike B. suggested and put it all together....no more issues when hot....less than 2 hrs work,but I took my time and cleaned the area thoroughly so there was no grease or oil to mess up the connections........THANKS GUYS.....really not too bad of a job:322: Link to comment Share on other sites More sharing options...
