If i would be in Your trousers, i would adjust both, as its easy job...  If You take half rings away, put some ear plugs to oil channels, that half rings cant go inside engine...  Btw, did You remember to drive engine with high RPMs before adjusting, as valves MUST be CLEAR from shit before You start make adjustments? Adjusting only with cold engine! |

[quote="Finnpaso"] If You take half rings away, put some ear plugs to oil channels, that half rings cant go inside engine... Ha ha , I learnt this the hard way. I was reduced to tying a small fragment of a magnet to a piece of dental floss and dangling it down the hole, to no avail . Eventually I kicked her in the guts , went for a short ride and removed the sump plug , and there it was stuck to the magnetic bit on the plug . I have found that if your closers are a bit loose ,it can pay to check those 1/2 rings as they do wear and replacing them can make the difference. I set my closers at zero clearance , so that I can just rotate the shim with oily fingers. ducatitech.com has a short vid on how to do this valve clearance thing ..... worth a look |

Hey Finn Yeah, it's definitely a cold engine. She hasn't been fired in about 2.5 years (which explain my absence from this forum). So I didn't get the high revs in, but believe me - the valve chambers are pretty clear.  I've done valves on my Monster (a couple years ago, now) , so I'm not unfamiliar with the process - but considering my measurements were only marginally out of spec, and the the sort of vague opinions around the internet, I just thought I'd ask the question here anyway. I had a length of solder attached to a 5mmx20 screw which I dropped into the oil return holes, but I think I like the ear plug idea better. The solder was handy because it was long enough to get looped over the side - so you couldn't put the valve cover back w/o first removing it. I don't think I'm likely to forget a brightly-colored ear plug though, and that would seal the hole much nicer. Good call. And makes sense to adjust both, yeah ... @McTool: that describes my closers pretty well. I can turn the closing shims when I load the closing arm. And the loaded gap on the opener is marginally higher than the unloaded gap, which confirms it. Guy Martin recommended to me the same thing w/ the closers, upon a discussion of the Monster (I bought his collet kit for the Monster; may do the same w/ the Paso, we'll see). Thanks all. Cheerio!Jake |

The ear plugs are a good idea , I plug the holes with a bit of grease , but yeah ' a bright coloured earplug would be hard to miss, and if your of a " thrifty " nature you could still use it as an earplug, certainly would slide in easily

Hi guys! That "earplug" is old "trick", what was one of first ones i learned from local guys here who have played very long time with Ducati engines, when they showed to me first times how to adjust Ducati valves...  Its little funny, that i put allways papernote before valve adjusting to fuel tank where reads: "Muista sitten ottaa korvatulpat pois!" = "Remember then to take ear plugs away" I have never forget ear plugs to oil channels and never dropped anything to inside engine, but i have heard one case from Finland, that such "used"(and very hard!) earplug have been found from that area just close that coarse oil filter(without any harm to engine), so remember to take them away after all is done before put valve covers on...

With my 2V Ducati engines, I shoot for 0.004"-0.006" (0.10mm-0.15mm) for the openers and 0.000"-0.002" (0.00mm-0.05mm) for the closers. I've heard of the clearances that you mention, but I just what I listed (I think I did my metric conversion correctly). |
