I ran an SHR860 this year. super strong engine and had 0 issues all year. Actually I had two but non-engine related. My fuel pump quit (while I was climbing Swenson street which really sucked) and the stock secondary was very inconsistent causing bogging (that one took a me while to really figure out), so I replaced it with a Team secondary and now the sled just plain rocks.
Jetting is at 460 mains, stock needle clip position with no shims. I run the 14:1 head and add 2 gallons Av gas per tank just to be safe...
I've owned a TNytro last year and this sled is way more fun, not near as much power but will get you pretty much anywhere if you push it to the max!!
running a linderman kit on mine. Love it, always impressive. Pump gas setup for jetting i am running a 540 with .30 shims under the needles. Last ride out i had a bit of a lean showing, might have to up another. I would definately recommend this kit to anyone doing one. Plus you are supporting the canadian economy
yes and no... yes if your gunnin on it all the time, no because i use a crap load less throttle everywhere i go. to me it doesnt matter, bottom line is that it takes fuel to make power. Lol if i gatta pack a jerry to kick the crap outta my buddies, so be it:d
