Haven’t done that one yet.
Hello Access Norton members. I've owned a 2013 961 SE, #10 of 50, built 5/14, for almost a month now. It was purchased from the original owner with 1240 miles on it. I used this site before purchasing the bike and received invaluable info from the members. I have literally done everything to this bike with the parts I received from the previous owner and my own purchases. Head bolt torque, coil, plugs,sensors,wires,Shorai battery,flush all fluids and adjust the "idle screw" with install of a stainless steel locking nut. The bike also had warranty work done 10/16 with new starter, crankcase oil breather, replacement of cush drives and inspection of clutch primary. At this time an "updated fuel map" was installed. This brings me to my question/request. This work was done by Munroe Motors. I spoke with someone yesterday in Service. They were not able to tell me what Map was installed. Huh? Does anyone out there have any idea or an educated guess as to which map a dealer would be installing from Norton on a 2013 SE with stock pipes during the 10/16 time frame?
Thank you and HAPPY THANKSGIVING!!!
The map will be 076 but its the revision that makes the difference. I believe 0116 (jan 2016) was the latest revision so you may be fine.
Thank you Richard.
One of the "extras" I received from the previous owner was a set of brand new SBN mufflers. They have now been installed. Can't seem to feel much difference in performance, but it sure does sound better. Do you think the present map that is installed should be good enough or would it be worthwhile to send the ECU off to Jonathan Reece as you had previously recommended?
Send to Jonathan. You will need the ecu remapped for new mufflers.
Thank you very much for taking the time to answer my questions. It is much appreciated!
What seems to be the consensus as far as map number for the SBN pipes? #77 or #91? Or, does Jonathan do something different with the ECU than the Factory settings? Also, pardon my lack of knowledge , but what is a re BIN file?
Thank you again!
Are the SBN silencers Dominator, or Torquer units?
Are you using the standard Xpipe with cats?
My 2013 CR with full SBN system never ran properly until I had the 090 map installed.
Previously used the 077 map that was better than the stock map but produced several flat spots, and surging.
If you are using stock Xpipe with cats and Torquer silencers, you may be able to get good results with map 077
If you have decatted xpipe and Dominators silencers, maps 090 or 091 will work best.
The 090 and 091 maps were designed for the Norton Dominator motorcycle not the Commando, but work well on a Commando with the full SBN exhaust.
All of the Norton maps are designed to work on Norton supplied exhausts, not for other aftermarket exhaust systems.
So if you remap your 961 with the SBN exhaust be aware that it will run better, but will probably still have other minor issues.
My CR still has cold starting issues, and slight cold running issues.
To really zero in on the proper fueling I'm planning to have a Power Commander installed shortly.
Thank you for your nicely detailed response!
I have the standard Xpipe with cats. The label on the side of the box the mufflers (silencers) came in says: SBN-916SM (yes, it says 916 not 961) and then below it says: Bright Polish 0515. I'm guessing 0515 refers to the production date? It's looking like #77 is right for my set-up.
Check the side of the SBN muffler facing away from the bike in the area just before the reverse cone section.
It should have a stamping in the steel tube that says either DS or DT.
DS is the Dominator Sport (very loud), DT Dominator Torquer (not as loud).
The only stampings are the letters SBN in a stepped pattern. The letter S being the highest with the next 2 letters being a 1/2 step below the previous one. This is stamped on both sides in the same place.
Your silencers must be a newer design than the original ones that SBN sold.
Did the previous owner provide any info on the SBN exhaust like an invoice, or correspondence with SBN?
No paperwork, but he did refer to them at one point (in an offer to help someone out and sell them) on this site as 2nd Generation SBN mufflers.
Get 90 or 91 if you can, Norton poo pooed these for US road use after the VW multi billion $ fines. the After market 016 map would be my next choice!
I had the generation 1 SBN DT pipes with map 91 until I went down and put a little rash on them. I bought a second hand set of SBN with the SBN logo on them, which are more upswept and have separate hangers instead of the welded on ones. The bike started and ran flawlessly with the original pipes. Now it idles a little higher when hot (14-1600) and has a few other minor niggles. I think 90 and 91 was developed by SBN to go with the pipes and Norton more than once did not want to deal with my running issues unless I was using map 77. Map 77 was HORRIBLE with the SBN pipes. Starting took multiple tries and having to give it some gas, flat spots and vibes all over and would idle at 2400 rpm at the lights. Since you have no warranty issues, go with the 90 or 91.
Thank you Gentlemen for all the good input. I'm counting 1 vote for "good results" with #77 and 2 votes for #90 or #91. Please keep the advice coming.
I have the upswept SBN's that Britfan60 refers to. They look great to me and the chain clearance issues (as compared with stock) are no more. I now have the stock ECU settings with revisions that were done in 2016. Starting normally requires a little help from the throttle. It used to stall 100% of the time coming up to stops until I adjusted the "set screw". Now it doesn't stall 100% of the time. Nice change. However, I do have some pretty significant "surging" at times. This is usually at lower rpm's and slower speeds. One time it was so extreme it was like riding a buckin' bronco! I couldn't control the surging with light throttle manipulation and had to shift to the next gear.
All the " issues" with the 961 are, in my opinion, interesting challenges. I have a slightly different perspective on things as I was wiped out last Nov. after being hit nearly head on by a driver not paying attention. My 2007 BMW GS Adv., that had nearly 90,000 miles on it, is in bike heaven and I darned near joined it! I have spent the last year not being sure if I would ride again.
The Norton 961 is the perfect medicine. An "old school" bike with modern features that the owner can still work on. That is very rare with today's motorcycles.
... and in addition ground clearance is perfect with these pipes!
I'm not really sure how many folks East of California have the SBN pipes. It seem more have the Motads which are now manufactured by the factory.
I have them because it was the only offer my dealership offered me at the time. I had no idea where the pipes were coming from. Norton or otherwise. All I know is I wanted louder pipes. Mine is one of the first boatload of Nortons and there was literally no further info. The bikes came first, the service and info came later. Thanks in part to this forum and so much to Richard7 and his dad.
I have them (2nd Generation SBN), if you count Switzerland as East of CA...
No more issues with chain or ground clearance, great sound, but had to get used to the look with the upswept angle of the pipes!
These are SBN pipes which touch on bends ( lots of scrape marks) but do not touch chain.
If you zoom in to bottom corner of upsweep you can see the scrapes.
