well after some issues with my head studs, ive decided to take out the 975 top end and put on the stock 900 cylinders/pistons/head/ECU. FOR NOW...will work on my issue and try the 975 again when i am in Alaska...I REALLY LOVE THE POWER!
long story short, i have headstuds installed in the cylnders to head keep the head down under the increased compression and HP. But after the first ride, 1 stud came loose, fixed it, came loose again, had to get threaded inserts installed cause the threading on these 900 cyl SUCK, a different head stud came loose and pulled the instert out...
so, that clyinder (MAG) is basically junk cause the jacked up thread holes. got another cylinder from Z-Man to use, so will work with that in the meantime and go from there. (HUGE THANKS)
got 350 miles on the motor and when i wasnt have head stud issues, it was SICK, loved the power.
got a SMOKIN deal on a set of used 05 900 cylinders from Jerseyrider on the forum (HUGE THANKS) so i will use these for the stock 900 motor until i work something else.
PLUS...we 975 owners are having issues getting the 975 pistons as well, Carls kicked us to the curb and will not help anymore, so have to get 12 pistons at a time from Weisco ($225 each BTW)...so that is also a factor for me right now.
but overall, this sled looks, and rides SICK!
