Title: Not another Valve question thread.
Post by sawkuh on 02/10/18 at 11:39:34

So I apologize before hand but I'm in a bit of a pickle with this one. I never did valves before and never saw them done (grew up in a harley family) and I tried it the first time (video one) and had the clearance way off. Read around and searched this forum and got loads of pointers like bending the feeler and what not. Did it the second time and found the intakes were way over (.009 and .010) which explains the clatter. Jump to this morning where I tried again, did it the whole nine yards, removed the plug and put in a screw driver (crank lined up in the same spot i did it before) put it all together and it was a bit loud yet. I know I had it on the compression stroke both times and I rotated the crank CCW.

My question is, I never had the bike when the valves were in spec. every arm was tight when I went in the first time. Bike has just under 9000 miles from 2002 and I'm assuming that was its first adjustment. What are the valves supposed to sound like. They did have a tick back when I first got the bike and I figured that was what they were to sound like but checked the valves to be safe.

The second video is where its at now, all the clearances measured .004 and a .005 wouldnt go in but a .004 was snug. Checked them all 2-3 times Is this too loud? I dont have a reference to compare it to. If there was a video around I apologize but any video I found on youtube had a loud exhuast and I couldnt hear anything from the valves.

Sorry, Dallas. I was thinking about going to a dealer but I havent gotten that far into the problem solving yet. by all counts the valves should be in the right place but that noise is a bit much I feel.

Could be a number of things. If the bike has been run with the oil level too low, that can cause enough rocker arm wear that the rocker will thingy while adjusting one valve and throw off your measurement. The same if the oil was of the little or no zinc variety, but that takes longer to wear that much. If the bearing journals in the head are worn that will affect your measurement also. But given the mileage yours has, I am leaning more towards just a error when adjusting the valves, eg. something slipped and you didn't notice it.

Freaking word filter.... "thingy" was the four letter word beginning with "c" that means "it tilted to one side" or another word for a rooster... :-/

Im just hoping its a small error but it was more so that I never got to hear the bike with the valves right. From the start they were tight but who knows what the owners before me did.

The Motion Pro feeler gauge makes life much easier, buy two.

Make sure your rotating the motor to TDC in the right direction ,the motor turns the same direction as the wheels . If your following the Clymer book it's wrong !

Yeah, I went over the write up verslagen1 did about 6 times. CCW, each time, never rotated it backwards if I missed it. Stopped the crank on the mark right after the intake valves closed.

You might try checking the decompression solenoid adjustment ,if the cable is too tight the rocker arm could be hitting it.

This has been the subject of my friend and I as of late. Between us we own 4 of them. Three of them we have done the valves and it is a major improvement on the two we have ridden both in sound and performance. The thing we have discussed is that ALL of them were extremely tight when we went in. They must come that way from the factory is what we are determining. EPA maybe? We know that at least two of them were done by us the first time because of the mileage they had on them when we bought bike. On ALL of them we had to backoff the adjuster to even be able to get any feeler gauges in.

Perfect, it's the things like this that have really been racking my brain. With how it sounds after the second adjustment doesnt sound like its going to explode but it also isnt like it was when i took it apart. This thread was more so looking for a confirmation that the sound in the second video is infact too loud. Because it's kind of hard if youve never for sure heard the right valve tick.

Just reading things like this helps me to realize that I wasnt as far off the mark. If everyone said "mine were hella loose" then Id be worried if mine were tight.

I think your second video sounds about right. Two of the bikes that were ridden were set at .004 all the way around. The third is at .005 tuned but not yet ridden. I am mechanically inclined but my friend is a very experienced diesel mechanic. I think you will be just fine.

Thanks for the response, you're basically my angel. If you're ever in Dallas you have a beer waiting for you. It doesn't sound bad at all, just didn't sound like it did. Dad was a diesel mechanic and he just said that loose valves are happy valves. Said the sound didn't seem out of the ordinary so here's to hoping.
