CHECK them every 12,000, but you don't "adjust" them until they measure out of tolerance. I had to adjust a couple at 24K. Not every 12K check after that needed adjustment, but by 85K all of them had been adjusted once.hoodoodrum said:What...I have valves???? Yep almost forgot as my LT is super smooth at 18k and my last Guzzi had LOUD valves. Anyhow with the engine running like a sewing machine on steroids, when "IS" the best time to adjust the valves?
Put the transmission in FIFTH gear, you can bump the engine around very easily by rocking the rear wheel. It will not work easily in first gear, ratio too high.hoodoodrum said:Thanks guys.... are there more detailed steps to follow other than the ones in the LT service manual? For instance, it says rotate the back wheel to spin the engine and cams. I assume in first gear of course, but what about releasing compression in order to spin the engine?
I do one cylinder at a time, positioning the cams so that both lobes are pointing out at the same angle (approx. TDC for that cylinder)hoodoodrum said:Thanks David
Do you work from the forward cylinder intake (top) and exhaust (bottom) to the rear OR run the intake valves front to back and then do the exhaust front to back?
I did a check/adjust as you suggest and found it took considerable effort to rotate the rear wheel in 5th gear. Got her done but I had to really muscle the wheel around.dshealey said:Put the transmission in FIFTH gear, you can bump the engine around very easily by rocking the rear wheel.
Don't try to just muscle the engine through compression. Grab the wheel and using the slack in the drive train just move it back and forth, "bumping" the engine through. Takes very little effort.oldschool78 said:I did a check/adjust as you suggest and found it took considerable effort to rotate the rear wheel in 5th gear.

It would be very unusual to hear valve noise increase on the "Brick" engine. The valves invariably get tighter, thus less noise than when valve clearance is correct. It is exceedingly rare that valve clearance will open up, and if it does, there is something nasty going on, like cam lobe wear, or worse, cam bearing bore wear.niobium said:Bruce,
You're not all that special; I just had a 12K done on my 05 and BMW of Miami told me that seven of the valves needed adjustment. I kinda suspected I might be hearing some valve noise during the last 2-3k miles before the service.
It is not at all unusual to have to adjust TIGHT valves, but the comment about them sounding louder would mean LOOSE ones, which is extremely rare.niobium said:Thanks, David. I'm gonna find out which way they adjusted them. Having read that the LT does not ususally require valve adjustment at the 12k, I'm hoping this is not an omen of BAD THINGS.
