had the 700 m10 out today after getting the rear shock assembly back fron team fast.they said that they would rebuild it and it would be better than polaris valving.WRONG.same old crap,after about 2 miles of whoops the damn thing is like a pogo stick.nearly launches ya off the seat.have to sit and wait about 30-40 minutes and it tightened up some.then when the trail got back to just choppy stuff it regained its shock ability.anybode else have this problem with a m10 shock.ive had it rebuilt by 4 different guys and its still the same.seems like it gets hot and then cools.the resivoir was completely covered in snow.as was the whole underneath. [had this posted in the wrong section]

Boy that doesn't make much sense. How big are your whoops? Have you talked to Fast? Have you tried another M-10 on this same trail or riding area?

8-12 inches but fairly close together.5 sleds ahead of me with edge left me behind no problem.this suspention has always done this.wish it had a chain under the seat to keep it from extending so much.

Here is a good article on tuning the M-10 suspension. Maybe it will help you.
