Have the flat tappets been replaced with rollers ? Dusty
If your dealer isn't too good, the early Norge 8V had a bad map besides the tappet issue. If they can't figure out what is going on they can call the Regional Tech Rep from Guzzi. This is what they are for and not to use them is plain stupid.If you hit a deer it could have damaged a wiring plug, relay or the ECU is right under steering head.
A flat spot between 40 and 4200 RPM seems strange to me. I understand you to mean that the flat feeling goes away at 4300 RPM, right? Is the problem purely RPM-related or does it also depend on the load, that is, whether you are getting to that RPM range in a high or low gear or on the highway versus around town?Was your bike damaged anywhere around the engine when you hit the deer? What sort of damage did it receive in general?Edit: Looking back, I see that the flat spot developed sometime after the deer hit. Maybe the two are completely unrelated.Moto
Excellent advise. How would one find the regional rep?
Where are you at? All tech Reps are on the inside of book you get when you go to Guzzi Tech training. If they have not sent anyone out to CostaMesa then it's inside their dealer book. OR they could call the warranty dept.If your warranty says Flat tappets were replaced but you don't see rollers then you still need it fixed.
If you've owned the bike since new, should have got a notice about roller tappets.
