Factory Yamaha " computer scanning tool " does one

I know where the starter relay is, never even thought of that I will check it today.
After buying the sled new for two years never really did a deep clean...the spring prior to putting it away I pressure washed it for the first time....could be the prob....
And I did Do all the checks from speedo.....all things responded correctly from the hand warmer toggle with zero code generating....
 

Checked starter relay " no corosion " now the sled started today and idled lot better but not 100% but won't rev up and out....it's like a switch. One time rev out and no idle only starts giving it throttle...next time turn the key and poof " idle with out throttle but no rev out.... Hard to believe no one has had same problem.....guess I gota wait for manual to see what's next

Scott - I cannot find the post I put in the General Talk area. If you want a free copy I can burn it onto a CD and send it to you. PM me if you want one.
If several others want it, I would prefer to put it on this site somehow. anyone know how to put a 50+ MB file on this site?
I downloaded it from your post but also cant find it now. If you google Yamaha nytro service manual it comes up as the first search item and it's a pdf you can save to your computer
 
for those of you following this post I did find the website were I was able to download the 2008 - 2010 service/tech manuals. I put a new thread in the Nytro General Talk section with the address listed in it.
 
For those people following this, i down loaded the Yamaha manual with the help of a great fellow member. well after many checks and double checks I concluded that the igniter / CDI box is bad.... Yamaha wants like $750. at a discount
Ordered a good used one from a dealer in NH that had just started parting out sleds.
$213.00 shipped to the door, got the package today opened the box checked it out no damage. installed it and WOW.... started and went to fast cold idle 2500-2800 steady RPMs less than a minute later 2400-2300-2150-1900-1850-1700-1650 ish perfecto ! just like the day I brought it home with zero miles.....
thanks for all the help from everyone !!!!! I will help and pass on what ever I can in the future... :Rockon: :rocks:
 
I don't understand why Yamaha snowmobile devision does not have a DLC connector. Every EFI Yamaha outboard and PWC does. We have all the software to read and troubleshoot systems. Plus being able to take a 30 second snap shot of loads while running from idle to WOT. Plus the ECM stores a history of rpm, trouble odes, hrs ect. Crazy to not have this available.
 
Sure it did. I was merrily expressing a displeasure about the Yamaha devision with me DLC connection or ability to store history like the outboard and pwc devisions.
