The OBSERVED Valve Clearance thread

[dave]

Dave,

I am curious as to what was challenging? I'll be removing my stock cams and installing new ones soon.

I've had my valve cover off before to swap from black to brushed. Wasn't horrible, but I know that is only the beginning.

Hi Josh. Removing the valve cover was a lot of work, at least I believe it is. I am used to working on older bikes where everything is much easier. Just removing the gas tank on the CB1100 is a real PITA. There is about 3 inches clearance to gain access to the fuel line disconnect valve and you can barely get your hands in there. I compressed the plastic tabs as far as they would go, using a needle nose pliers, and the joint would still not come apart. I resorting to using pliers and a screwdriver to force the joint apart and I cracked the plastic connector, which cost $80.00 to replace. I can remove the gas tank on my CB750F in about 60 seconds, and it doesn't require any tools. Removing all of the items on top of the valve cover was very time-consuming. That metallic clip, with the two nuts welded to the ends, is a really bad design also. It is nearly impossible to even see, and even more difficult to even touch, and it will fall out. I epoxied mine to the plastic heat shield before reinstalling it. I am sure the job gets much easier after you have done it once, but I believe that it would take about tens times as long to adjust the valves on this bike than it does for my old CB750. Even my VFR800 is much easier, and with the gear-driven cams on the VFR it makes cam removal much easier and quicker. Did you have any difficulty disconnecting the fuel line? How did you deal with the metal clip with the nuts welded to the ends?

Well snap, this is in direct contrast to all those in my swapping tank thread who said it was easy peasy. So which is it??

Everyone has their own comfort levels mechanically.

I had no issues with any of it but I’m used to taking apart the most complicated car ever built.

I would not say that taking the gas tank off to swap it as you want to do is difficult, but there are some fidly bits.

You want to pay attention to things such as not over tightening the fuel pump flange and being careful when transferring the fuel pump because of the level sensor arm. Make sure the gasket surface is clean etc.

So I suppose I would not just throw someone who is new at working on motorcycles, cars etc. at this job unsupervised.

It helps to have a prehensile tail
But! I did it once and lived to tell, so you almost certainly can, too. I find it always helps in stressful situations to have a friend on hand to cheer you on and hold your beer. But mostly, patience will pay off.
Go for it. Anything you do wrong can be easily fixed for not much money and the pride in a job well done will be worth it.

A healthy fear is a good thing- go slow, be careful, triple check everything- and don't use pliers or screwdivers on soft plastic bits.

If the thought of going up in flames due to your own screw up scares you- pay a shop.

And for the record- I don't trust any shop. Doesn't matter it a car or motorcycle.

Pickle eh?

Hi,
Did you pull the black rubber plug away from the blue green clip?
It fits into the slots in the clip to keep it secured.
It is impossible to release the fuel clip without removing it

Yes, I pulled the black, rubber plug back first. I squeezed the plastic tangs as far inward as they could possibly go (until they contacted the metallic nipple on the fuel tank), and still the hooks would not disconnect from the connector. I was forced to use a screwdriver to bend the plastic hooks outward to release clips and I cracked the plastic housing. Am I the only one who experienced difficultly disconnecting the fuel line?

PowerDubs: What is the most complicated car ever built? You evidently have a lot more experience working on newer vehicles than I do, and a lot more patience. I can do three or four top-ends on my YZ250 (2-stroke) quicker than I can just inspect the valves on my CB1100.

Other than warranty work (which was extremely limited) I have never taken any of my vehicles to the shop for repair (I have owned 33 motorcycles in my lifetime). I do not trust anybody to work on my vehicles.

VW Phaeton.

We have had 4 so far in my family. I've owned 2, my father in law has owned 2 of his own, and he has since moved on to a Bentley Continental GT which is basically the same car + 2 turbos.

The Phaeton is actually substantially more complicated than the Bentley in many ways- it's climate control system for example.

As long as you got the bike apart and back together with no lingering issues- what happens in the middle doesn't matter to anyone other than you, your time and wallet. We've all had stuff break.


Totally off topic, but here is a taste. Amusingly this picture does not contain all the options available- such as refrigerator, solar panel sunroof, retractable power desks for the rear seats, reclining rear seats, etc. Really an incredible car once you delve into the details.
