osiris Posted May 28, 2013 Report Share Posted May 28, 2013 (edited) Dear members and riders! I'm happy to join your comunity. I bought the Sherko 2.9 2011 in GB and delivered to Russia. It looks unbelievable and took just 3 weeks. I assebled the bike and started it simply. Firstly, i washed it by hi pressure and some water has poured in to the stator through the cables. The spark was disappeared. Two weeks the bike was tested in order to find out where the problem was. Initially we suspected that the Leonelli CDI broken and i bought a new one. Suddenly, the seller returned money. All mechanics, including Splatshop's, claimed it is hardly related to CDI. However, we begun to test the stator plate and coils. We disassambled it detaching the trigger. The trigger consists of 2 magnet sensors. One of them uses for engine start (when we have less than 1000 rpm) and this sensor is located +20 degree. It is appropriate idea 'coz the CDI can't determain precise rpm and doesn't have the map up to 1000 rpm. The second one uses just for normal motor work. We tested both sensors and found the first was broken. There are applied 2*SS543AT unipolar magnet sensors by 2$ each. I bought the same sensor here in Samara, Russia - SS511AT - and attached it instead. The bike has started perfectly. I sincerely hope the desicion will afford you to save a lot of spare money and time, because the problem mostly happens with the hall sensors. I could have buy a new stator (aproximately 150 pounds) and a CDI unit (270 pounds) and wait delivery up to 1 month. Finally, the problem had been solved investing 2$ on the place. I could advise to test the stator (pins) at first. Hardly the problem is related to CDI. Thanks! Edited May 28, 2013 by osiris 2 Quote Link to comment Share on other sites More sharing options...

copemech Posted June 3, 2013 Report Share Posted June 3, 2013 (edited) That is good information. Where did you find the part? What is the difference between the two part numbers? Edited June 3, 2013 by copemech Quote Link to comment Share on other sites More sharing options...
osiris Posted June 6, 2013 Author Report Share Posted June 6, 2013 copemech, SS543AT and SS511AT are magnet sensors which used in the hall sensor on Sherco 2011. We just opened the stator and these small sensors were placed on the plate. Even the 511 is not a unipolar sensor, it is suitable anyway.

Holster Posted August 25, 2018 Report Share Posted August 25, 2018 Thank you so much osiris for posting this. I have just made the (exact) same repair on my 2011 300 Cabestany. I had to get someone else to do the soldering but I still got away with a $50 repair instead of a $300 replacement stator. My bike became a bit temperamental and was getting harder to start when cold then eventually wouldn't start at all but would sometimes kick back and nearly break my foot! The stator tested OK but I had read that it wasn't necessarily a guarantee of a good stator so I figured changing the hall sensors was the cheapest option to start with. SO happy to be back on my bike. If you are ever in Brisbane I will buy you a beer!! Cheers Holy 1 Quote Link to comment Share on other sites More sharing options...
