The part number should be 8000B3207 and it is the same for the 675/800 range too.

Does the bike have the latest ECU map loaded? It was released in service bulletin 166 issued in December 2015. That upgrade did include some changes to the starting sequence which improved starting on my F4RR. The map version for USA/Canada is 0515FF38. (My bike is a euro version so has a different map).

Have you tested the air temp sensor and found it is out of spec?

going to check air temp sensor next week , its so chaep to buy a new one it just makes sence to replace it at the same time seeing as how the front of the bike has to come off to get at it

thanks ! and yes i checked across the board on all 2013 MV models and they all came back with same part # and same part !

there are a few on ebay so i might go that route

is there any why to replace it without removal of the front of the bike ?? i looked at the manual and it looks like alot of work to get at ?

will check battery conections again but i think its fine there , the bike was haveing issues starting before the valve work so i thought it just needed new plugs and air filter , but still has cold start issue ! once started it runs perfect and will start no problem when hot or warm ,
I do belive the MAP was updated 2 years ago my mechanic is very good at keeping my bike in perfect running condition but this cold start is something i am trying to trouble shoot a bit first before i take it in

First things first...you obviously have not tested your current unit otherwise the bike would already be disassembled. This could be as simple as a dirty connector.

Before you source a new component, why don't you ensure that the current component is bad?

absolutely i will check air temp sensor , and i was able to locate it and access it without removing front of bike , just the right hand side air inlet cover needed to be removed was a bit tricky to get out but i managed, and located the ATS unfortunately thats about as far as i can get as i am not good checking things electrical , i did disconnect the wire and inspected it for corrosion or and breaks non found !

reason i was sourcing the part was i figured i would start looking for one now and cross referenced part #s from several 2013 mv bikes to have the same part # and readily available on ebay, because i have things on order direct from MV for over 3 months now and still no part ,

and honestly now i can take the bike to any shop and have ATS checked and replace it myself , My regular mechanic would have charged me a easy hour to inspect and test it and he is not very close to me so what ever i can do myself i usually do.

but much appreciated on the confirmation of part # !!

Thumbs up ?

rulookin;
To test a temperature sensor you need an Ohm meter, water, a thermometer and a heat source
It's simple and in the Manual
