i'm definately no guru but the 1200's do take shims, no adjustments.The 1200 gurus should confirm this.. but I do believe the 1200 has hydraulic lifters.. probably hearing one with air in it from time to time..
Here is one possibility, check for any loose bolts/nuts around the lower left side of the engine/exhaust area. One of my riding friends was absolutely convinced that his tapping sound was valve problems. Then by accident one day while cleaning his bike, he happened to notice the nuts on the studs that connect the exhaust pipe to the header were loose. He tightened those nuts and it fixed his valve problem........My 1500 started tapping on the left side today. I just noticed it today. Heard it after changing fuel filter and cleaning air filter. Any ideas?
Yea, I'm paying over 8 bucks a can for it now when last year it was around 6.50.I concur with the Seafoam....May have some partial blocked oil passageways. Add it to the crankcase and change out after about 200 miles. If it still drains dirty after filling with fresh oil, do it again. The stuff does wonders. No wonder, they jacked the price up. I'm sure, we had an effect on that.
A cheap and easy fix to try first. I'm all about cheap and easy......
