1st time valve adjustment

bdfinally · May 01, 2012, 05:02:13 PM

Speeddog, I think I'm confused, but we'll come back to that.

I pulled the intake shims off the vertical this evening before dark. I think I might have another problem. Like I said I bought an EMS closer tool over a year ago and finally tried to try it out but think I was sent the wrong one. Their website shows it as looking like this in use.

This is my closer with the tool they sent me.

and inside the shim

which only lets me measure the tool size. The only other orientation that doesn't just measure the tool gives me a measurement less than the .393" (10mm) they say needs to be subtracted for the tool size. Am I missing something obvious...wouldn't be the first time.

Anyone confirm this is the proper tool for a '00 M750?

BD, my M800 uses 8mm valves, I think like your 750. The EMS tool I got from them and used on my valve jobs looks like the pic on their website. I think you may have the tool for the 7mm valves.

Thanks Battlecry, I sent Mike @ EMS an email to confirm and arrange an exchange

Well I've really got egg on my face, got a quick reply from Mike saying that's not his tool

Now I'm racking my brain trying to remember where I got this thing. Funny cause the polybag has my name written on it, in someone else's hand and is marked 2v shim tool. Anyone recognize it?

Anyway, I'll be getting the proper tool from EMS shortly.

Got my openers measured and figured sizes for new shims. Waiting on my closer tool which should be here Saturday. My question now is is there any relative advantage in shim calculations for both openers and closers at the same time other than the "run out to the ducati shim store" again? Could I go ahead and buy my openers today, put the closers back on and do the fine tuning on the openers to get them to .004 & .005 and then do the closers this weekend?

Yes, but don't get them mixed up!

I'm using one of these to keep everything labels and separate

Ok, sat down and measured my openers and figured the size of new ones. The VIO is measuring at <.0015, my target is .004. Current opener is .1357 so I need a new shim .0025 smaller than current which would be .1332 converted to 3.38mm, so I need a 3.4mm shim and fine tune it by sanding. My VEO is measuring at <.0015 also and my target on that is .005. Current opener is .1449, new shim needs to be .0035 smaller which gives me .1414 converted to 3.59mm so I get a 3.60 and fine tune that. Does that make sense?

It does, but you shouldn't sand anything until you install and measure the new shims on the bike.

Also get a bubble level on the ground where you plan on sanding. You probably know you need a flat piece of glass but if your ground isnt level you'll end up having uneven forces when you sand.

My coffee table has never been leveled...it may become accustomed to it.

Mike @ EMS got my 8mm shim tool here in record time and I measured my closers. The VIC came in at .2518 (.6455-.3937 {10mm tool size}.) Add the .007 to close the gap to .001 and I got .2588" converted to 6.57 mm and I'll purchase a new 6.6 closer shim. The VEC was .2422 (.6379-.3937.)
Add the .005 to close the gap and I have .2472" converted to 6.27mm and I'll get a new 6.30mm shim for that side. Does that make sense?
