When I am riding hard and hit 80-90mph I get a bad vibration through the foot wells and handlebars and this also happens when I hit the throttle hard in the powder then smooths out after.What is the rate on the rear spring because I need a stiifer one as I bottom out quit a bit.

It sounds like you have something wrong with your track or wheels.

Yeah I was thinking something like that also but am new to Yammi and never felt this on any sled I have ever ridden.Again this only happens for a few seconds at these speeds then it is gone.If it was a wheel or my track you would think that this vibration would be happening more than it does. 
Sled only has 433 miles.

What size track do u run? also I had the same kinda problem, The track was loose for hookup and it would slap the end of the slides in the front. Mostly at topend or in powder working hard. I made a few ajustments and gained 8-10 mph topend
I am running the stock 1.25 ripsaw junk until jan 14 when I get the 1.5 intense.I will check the track tension tomorrow.How tight should I be running the track?Thanks

Check the bushing in the secondary. As for the bottoming, you might want to check into getting your shock revalved.
What should I be looking for with the bushing?

Check to see if it is worn or cracked on the clutch and or the helix.

Not shure, I was @ longest setting on limiter strap and tightend it fully and tightened the transfer rod sum, I do get a lil less hookup, Its kinda a guess n test thing. id try 1 hole from Shortest setting and put sum transfer on. Also check the tightness of ur track, Ice buildup & busted bearings.
