Thanks Docc for renaming this properly. Do Guzzi's have hydraulic lifters? I assumed they were solid since the valves require adjustment.

This is a 99 Cali EV. I have discovered that I mis-identified the noise as exhaust related. I did a compression check and found that the left cylinder was lower (140psi) than the right (170psi). I pulled the valve cover off again and discovered that the left intake pushrod had come out from under the tappet adjustment screw on the rocker arm. I re-adjusted the valves (.10 / .15) and ran a compression check and had good compression (170psi) on both sides. I buttoned everything back up and put the plugs back in to start. Within a few seconds the noise returned and while I was out of time to dig back in I am confident a have a pushrod out of place again. While I am new to Guzzi's I have maintained my own BMW Airheads and Oilheads for over 30 years and have done many valve adjustments. I have never seen anything like this. Short of reducing the valve clearance what should I look at?

New owner (first Guzzi) of a very nice, running '99 V11e with 38k miles on it. Long BMW background with Airheads and Oilheads, all maintenance by me. No maintenance history from previous owner (estate purchase). Immediately discovered very tight valve clearances (none, valves not likely closing completely) which indicated to me that the valves had not been done in a long time and receded as on a BMW. Did a valve adjustment (.10 / .15) and starting and running behaviour improved immediately. However, a new issue manisted itself. At idle or low rpm (< 1500 rpm) it will "pop" intermittently inside the exhaust system, a funny, almost metallic "ping". It is not preignition / detonation. At 2000 rpm or better, the noise does not occur. It is not the heat shields as I removed them to eliminate that possibility after reading a posting here. My next step will be a compression check to see if I have a burnt exhaust valve from the lack of valve clearance. If ok, I will look at injectors. What is the collective opinion on this and is there any trick to removing the injectors from the throttle bodies. Thanks in advance for any input or guidance.
