Title: Norge 8V - 1st gear notchy
Post by: Cool Runnings on May 08, 2016, 12:55:49 PM
Do I need a custom exhaust with beetle's map in order to correct 1st gear horrors?

NO.. you need properly tuned bike, with the correct factory map. "Adjust" the EPA canister minimize its effects AND make sure the throttle cables have the proper tension. Balance the TB's and it will be fine!

So, sounds like I need to get after my dealer as it's under warranty through 2017 (about 1,400 miles now).

So, the stock FI mapping on the Norge should not be notchy?

When you say "notchy," do you mean that your Norge bucks and lurches at low throttle settings in first gear? If so, then Beetle's map largely cured my current Norge of that. I believe the bucking and lurching is due to the stock map being overly lean. (My Ducati was far worse!) Also, my previous Norge had an Agostini can with the DB killer removed. The ECU trimmed around the more open silencer, causing the engine to run richer, largely eliminating the bucking and lurching (and making the Norge sound glorious in the process!).

Maybe just a loose throttle cable.

Thanks Jeff, Beetle's map along with a new can are in the works. I want to hear some grunt. Besides, loud pipes DO SAVE LIVES.  :thumb:

Maybe just a loose throttle cable.

I was thinking a overly tight throttle cable. The smallest movement of the throttle and it lurches forward, backing off and it bucks. Not a lot of fun in stop and go traffic.

I have not tried a Throttle Tamer, but on e of those might help, too (if they make one that will fit the Norge):

Jeff, was thinking about that solution yesterday, may look into installing one?

If they make one that fits, I may give it a try, too. Beetle's map has been very helpful at eliminating low-speed bucking and lurching, but not entirely.

Who did the last throttle body sync and TPS reset. Maybe it just need cleaned up a bit.

On my first Norge, Moto Guzzi Portland. On my second Norge, Moto International. For both PDIs and first services. However, the snatchiness/bucking/lurching has always been there to some degree, at low speeds, in first gear.
