valve adjust problem (Not really)

Re: valve adjust problem

Scott - I will give bump starting it a try. It will have to wait until the ice melts though and I can't think of any hills within 50 miles. It would take some doing to get enough guys together to push that bike and my fat but fast enough in flat Va. Beach to give it a try.


Bender- I'll get that info soon.


Guess next is to pour the teaspon of gas in each intake? I'd have to have the airbox plugged in right?
Open the airbox and pour it into the TBs through the airbox?

Re: valve adjust problem

Just a question about the photo's you took of the cam timing chain and crank timing. The photo shows the timing on the number 2 cylinder not number one, was that mean to be?

Just following the manual, it has you check the clearance on number 1 first and then number 2. It then has you begin the adjustment process. We didn't necassarily decide to put it there, it is just where it was. Is there a potential problem with that?

Re: valve adjust problem

Well, normally you mark chains and such off number 1, then turn number 2. Installation shows you put the engine on number 1. I would put it on number1 top dead center, you should have clearance on all number 1 valves. Then turn to 2 do the same. Usually when something we work on doesn't start, that's where I focus.

That's a good catch, but as long as the cams were timed with cyl 2, it shouldnt be a problem. I could see how that could be confusing during reassembly though. I would typically get no. 1 cylinder at TDC and all the marks line up before tearing it down. That would be after making all the valve clearance measurements.

Did you ever align the marks against no.1 cylinder at TDC and it's associated cam timing marks after you got the shim issue straightened out?

hmmmm? Not sure but I double checked the manual and it does begin the procedure right after checking the clearance on #2.


This is a photo from Greg The Pole's write up, it seems to be the same.

I don't think I ever paid attention to that. You have to turn the motor a few times to get the marks to line up. Are you saying those marks should line up at TDC on cyl 1 and 2?

AC, Don't know if you watched his video or not, but the bike starts for about 1 second and sounds normal. (Not flooded, not mis timed)

I once had an SV650 that we mis-timed the rear cylinder on. It was a vtwin. Guess what? IT RAN! We rode it around the block and everything. It just didn't make any power and sounded weird.

I'm not saying it is certainly the case here...but at this point I think we are all just throwing darts at the board hoping someone gets a bullseye.

If you have the manual, take a look at page 5-16. It provides a tip to align the cams with marks on the crank. I'm not looking at your painted marks because I don't know your point of reference.

Not necessarily, he turned the crank several times, he can be 360 out

Holy crap, could it have actually been the sidestand switch all along? Registers on in both up and down position.

Re: valve adjust problem

Well on should be ok to run though?

In neutral the bike cranks with the sidestand up or down.

In first it won't crank with the side stand up or down with the clutch in. That isn't right? Right?

Should be able to start in gear right? As long as you have the clutch in?

Re: valve adjust problem

...and the sidestand is "up".

I don't think the bike would even crank, let alone fire, if one of the safety switches wasn't happy.

Do you have any new codes tripped?

Re: valve adjust problem

Yes, 1st gear, sidestand up, clutch in. It does not crank.

 

[snakebitten]

Re: valve adjust problem

Pretty sure it cranks and starts with clutch in, stand up, in gear.

Time to get the multimeter out. Check the function of the sidestand switch.

Re: valve adjust problem

Something no one has thought about yet...any chance you got the cam timing completely off? Any chance you are "180 out"? If that were the case, your valves wouldn't hit your pistons, but you ignition would be timed all sorts of whacky compared to the piston/valve conditions.

This doesn't appear to be the problem but it is something I have wondered about on reassembly if the cams and cam chain have been removed.....and I think the purpose of the cam position sensor is to synchronize the ignition with the crankshaft so you will never be "180" out. However, if the cam sensor is faulty then the timing could be way off.

Re: valve adjust problem

Will have to check it out in the morning.

I checked in the manual and the bike has to be in gear when you check the sidestand switch in diagnostic mode. It does read on-off when it is in gear.

Still strange that it doesn't crank when in gear, sidestand up, clutch in. My FJR would start that way.

Stall the bike on a steep hill and you have to put it in nuetral before starting it? This might still be a clue.

Re: valve adjust problem

Check your clutch switch. If it is disconnected, it will not crank unless it is in neutral!!
