Kickeroo Posted April 20, 2013 Share Posted April 20, 2013 Lost power at about 70 mph the other day. Ominous knocking coming from the engine, like one piston was along for the ride and nothing more. Oh no. Had it towed and am now awaiting the diagnosis. This is gonna hurt. Link to comment Share on other sites More sharing options...

GuzziMoto Posted April 20, 2013 Share Posted April 20, 2013 Where did you have it towed to? As mentioned, it can almost always be repaired (just a question of how much $$$) and major issues can be an opportunity for improvements. Sorry to hear, good luck.

fotoguzzi Posted April 21, 2013 Share Posted April 21, 2013 No Roper plate, not enough oil pumped at launch. Link to comment Share on other sites More sharing options...
pete roper Posted April 21, 2013 Share Posted April 21, 2013 Do a search. Its well documented. Poor pick up placement and design leads to oil starvation under hard launches. Pete 1 Link to comment Share on other sites More sharing options...

GuzziMoto Posted April 22, 2013 Share Posted April 22, 2013 If you run an internal combustion engine, Guzzi or other, without oil pressure (when that oil light is on it means you do not have oil pressure) it can toast the bearings. The big end bearing are probably the most suspect-able to lack of oil, they are plain bearings on a Guzzi and without oil pressure a plain bearing is not a bearing.

You will learn lot$ after this baby gets back together. When you are getting it fixed get a Roper plate from Pete Roper . Your tuition is going to get expensive for your education. If you dont know how things work, get come service manuals, Google & Youtube or ask the person fixing your bike to explain what goes on inside your engine..... p.s. information is going to be true,false or a combination.....it is up to you to decide what is real.
