gas will come out of the bigger vent fitting you just have to put it on the other side but i like the idea of not disconnecting tank i have not yet got filter back to were it was first time on side note drove the zong 1tenth of a mile to buddy's garage to adj. valves it was by no means hot took everything off to get it ready checked valves three hours later all good next day found one tight best let it sit overnight IMHO

I would like to try your method, but I don't understand the placement of the 2x4 lumber. The next time you check the valve lash, would you please take a photograph and post it here?

Last time I checked my valves I didn't move the tank at all. Just took off the side plastic body pieces. There is enough room to remove the intake valve cover and check valve clearance with tank still in place. Admittedly if you need to adjust an intake valve, a bit more clearance would be nice, although not necessary. Sounds like fjmartin's suggestion to use a scrap of wood to prop the front of the tank up would do the trick. For first timers, probably best to remove the tank to see more clearly what you are doing.

Spud, my plan is to do the valves either tomorrow or next week so I'll post an actual picture of what i'm doing with it but here is a crappy hand drawing of what it sorta looks like. I am NOT an artist :-)

Thank you, Joe.
I imagined you were raising the rear of the fuel tank, so I am eager to see where you place the wooden block to support the front of the fuel tank.

Tilting Tanks
Here are the pic's of how I tilt the tank to make valve adjustments easier. The 2x4 is 11" long. I place it under the forward tank bracket and the steerer tube. It holds nice and steady.

Oh, and it had been about 3000 miles since I did my last valve check/adjust and the intakes were again exactly where they've been since about mile 2000 but the exhaust valves were just a little bit tight. They are now adjusted. I'm at just a bit under 7200 miles now on the bike. Take care!

Why is it that when I set all four valves to 0.06mm and I crank he engine a couple of times then I go back to TDC. I check my clearance and like clock work, the exhaust valves are so tight that I can't fit a 0.06mm filler gauge. Then I check intake valves and its way over 0.08mm.
This is very frustrating. Here's how I did it and see if anyone can find a flaw in the way I did it. (This is my second time and I didn't have this problem the first time!!) 1. Set TDC. 2. Set all four valves to 0.06mm. 3. Turn the engine two times and re-check. 4. I get same results as above!!!!! WTF!!! |

Is there a different TDC for each valve (intake vs. exhaust?)

Here is a foolproof method for finding TDC on the compression stroke. Remove the two inspection ports at the top of the engine, and rotate the crankshaft in the counter-clockwise direction. Look for the "L" mark on the cam sprocket. After you see the "L" mark, carefully rotate the crankshaft until the "L" mark is aligned with the left inspection port, and the "R" mark is aligned with the right inspection port. When the cam sprocket is in this position, you are always aligned with TDC on the compression stroke. You don't even need to open the inspection port on the flywheel. Using this method, you will never make a mistake by adjusting the valves on the exhaust stroke, instead of the compression stroke.

Location of inspection ports?
Where exactly are the two inspection ports located?

Valves no load??
How come the valves are not loaded. They freely go up and down when I line up the TDC using the inspection ports?
Is this how it's supposed to be ? The valves freely go up and down? |

Yes, you must have space between the rocker arms and the valve tappets when the crankshaft is at TDC on the compression stroke. All is well. Set the proper valve lash, and you have completed the job.

Been doing it wrong. Thanks Spud!
So after three tries I couldn't get the valve clearance right.
Thanks to SPUD, it made all sense to me--I was doing it wrong on my first valve clearance check. It took me 4 tries and two days to get it right the second time. Thanks Again SPUD!! At least now I know how to tear down my bike for th next valve check. She's up and running!! |
