Adjusting DR650 Valve Tutorial PDF with pictures

Great post. Just what these sites are for.

Ah yes, BigBoy's very cool pictorial from Thumpertalk. I forgot all about it..... it is linked on the DR650 Wiki as well.

This site rocks! What a useful link. Knowledge is king.

This site rocks because of the input from all it's members!

I used this tutorial myself a couple months ago. I highly recommend getting the tappet wrench with the round knob on top and the bent feeler gauges from Jeff at Procycle.us.
I don't think that I could have managed it without the right tools.

How to know when (and why) the valves are in the correct position for adjusting:
Bring the "T" to the Top Dead Center mark, try moving (rattling up and down) the pair of valves you want to adjust. If they are tight and won't move at all, they have spring pressure against them and are not to be adjusted in this position/condition. Rotate the crank around until the "T" comes up to the TDC line again. Repeat the procedure of moving/rattling the valves again. If you can move them/rattle them slightly, they are in the correct position for adjusting. That "play" you feel, is the gap in which you will place the feeler gauge. If anyone wants to elaborate, feel free.

Thanks for the second method to tell the correct TDC. It is always good to have multiple ways to do things.
This is what is in the tutorial listed at the beginning of the thread.
"A way to find the TDC compression position (where adjustment should be made) is to remove the rocker covers and watch the rocker arms as you turn the engine over by turning counterclockwise or turning the wheel. When the TDC mark on the crank comes to the hole, continue turning the engine slowly while watching the rocker arms. If they DO NOT MOVE at all as you continue turning, this was the position where adjustment needs to be made. The other TDC is when the valves are in the overlap position. You will see the exhaust rocker arm just closing and the inlet rocker arm just opening and no valve clearance at all. So keep turning the engine until you get to the desired TDC. If you see the wrong one, then the next one will be the right one. If you just missed the right one, then keep turning through the next one and stop at the second."

Or to simplify: with the valve covers removed turn over the engine watching the intake rockers as soon as you see them open and then just begin to close shift your focus to the timing view port. The next T mark you see will be the correct TDC for adjusting all of the valves.

One more trick that may save someone some time or money. I tried the long, square drive wrench sold for valve adjustment and didn't like it. It's too long and doesn't fit in the confined space well, and it doesn't give any "feel". A trick I've learned before on Yamahas...a square drive wood (deck) screw has the same size hole as the adjuster screw. It makes a good, cheap "wrench" and gives good feel when you drag on the feelers. BTW, Procycles little, bent feeler gauges are awesome!

Are you talking about the tool or wrench?
I used the tool and it worked well.
One is right above the other on this page.
