Good grief on that job.
Brothers sled was running on one cylinder.
Sent him up the hill on my sled since he was out from Arizona for a one day ride.
Watched part of a B.R. video on getting top panel off.
Good thing doo did not make it tough with their tuned plugs changes. Enough screws to make cover part of the frame structure.

That would be fun on the hill!

1950km on Boost and zero plug changes.

900km on the doo and its let's scrape some knuckles and beer time to get it past the trailer.
It's out of break in, should be good now......lol

Best trick I have found for 850 plugs is to use a flex head ratcheting wrench on the hex part of the socket. Usually a 19mm or 3/4".

Doo's seem to be susceptible to fouling a plug when they are cold started and shut before warming up. (such as a quick load up) XM's in particular. You can usually clear it up by running wfo down the trail for a little bit.

I haven't done the turbo but the 850na can be done easily without removing the hood and no special tools. imo can be done faster than removing hood.
