engine pop

[unspace]

This saturday I took my rosso to bear mountain, it's about 160 mile ride round trip. As soon as I got out of traffic and was on Palisade parkway doing about 75 mph, I hear pop from engine. the poping continued for an hour, approximatly 10 times in all and it grdually stopped popping. on the way back it didn't pop at all. is this normal? was it over heated from traffic?

 

anyhow, I had so much fun on this trip, rosso loves curvey moutain roads

My Tenni will pop when stuck in city traffic.

 

Out in the country it runs fine.

Check that you don't have an exhaust leak at the header.

It could be that your throttle bodies are out of sync. Thats what mine does when the tb's are a little off.

Mine too, on roll ons at 2600rpm only , perhaps this has to do with injector synch and the little screws for air under the TD's.Mapping (A/F) is measured and is unlikelly.I will have check out.

Same here, I'm hoping after I get it balanced and dyno tuned they will be all but gone. knowing what I know about guzzi, or what I hear at least. Nothing is ever 'gone' or really fixed its just bodged up for now kinda program.

how do you find exhause leak at the header? I did find fine black dust at the tip of exhaust, it must be running rich.

You should find some of this black dust near the leak.
