missed your call today, I'll catch you tommorrow, lost my cell in the snow this weekend --to many BL's maybe?
tested the solenoid (dpm manifold) with a 9volt batt and it was working ( blew air in end (no power-no air, power- air threw end)
took it to the dealer and checked for codes = no codes present
tested rave valve relay = clicked like it was fine
pulled rave valve caps = they move free
unplugged every electrical connection that could be found = same
had dealer check throttle position sensors = 5% to 95.5% in spec
pulled head of last night ( rule out something coming apart)= pistons and walls looked good
was riding at togwotee guage said 9000' at time of fouling -- 10400' was the high of the day 8850' the low
temp was around 20'
I can't remember the last time I have rode below 8400'
Theory---- was leading the gals back to the truck ( one had wet feet to her knees from first creek experience)
traveling at or around 6000 rpms for about 2miles --fouled plugs
changed to new plugs ---- 1/4 mile of trail -- started dumping a cylinder so I started romping on it-- didn't seem to help-- flipped the choke on while under full throttle(thought maybe plugged pilot) made it worse
do you think that there was enough fuel left from first foul that it killed second set -- I was close enough by this time that i just stuffed it in the trailer-- I hope all this is from puzzy footin around-- the girls are on their own from now on- lol

forgot to add that until plugs fouled-- machine idled around 2200 rpm
now Idles round 1400-1500
now Idles round 1400-1500
Thats excessive,More than just rich, I would start by checking to see if pilot and main jet is tight and also that needle clip/retainer was installed correctly.You need to eliminate these first
thanks byeatts
checked needles = they where correct
jetted down from 470's to 460's that night
tried it next morning = same
haven't checked pilots I'am headed out to the shop after supper

I have never fouled plugs on mine, but she does get a little blubbery if I stay below 6,000 rpm for too long. 470's and .030 shim @9,500-11,000 ft.
While your in there check the float needle and assure it shuts off flow and level looks correct
After a call with Bob (hes tuning a 2010 also)...the 2010'
s seem to run richer...so remove the .030" shim and put a .020" shim...the drop the mains to 450's...BJ

I suspect twin pipes has a lot to play in that....
Woop.s missed that part. I had twins once...... Ohhh wrong forum!
Has anyone tried the Team setup with the new secondary with their 860?

2008 summit x 163, 860 kit with jaws twins and minor porting, 13:1 head, bondi box, stock reeds, 540 jets, .30 shim, stock gearing, 130/260 primary 2mm oversize rollers, no pin weight, 413 ramp, 46/42 helix, purple sec spring. clicker 4 @ 7000ft all day. Out pulls any NA sled i have seen so far.
Full setup or just the secondary?
Running Toms Heavy arms,433,s,Oversized rollers,160/320 and the new Team Tied secondary on the SHR 860
SHR 860, 14.7:1 head, pur/pur primary spring, 15grams, 413 ramps, 43-47 helix, pur secondary spring on clicker 3 and 4 in the snowies. Seems to work pretty good. Only complaint, takes too long to get the revs up to 8200.

Getting rid of the reverse angle helix would be a step in the "better direction"....
