Expert X stiffness

[yamahaboy701]

I have an Expert X 136" that was way to soft last year so I sent the shocks to Aaron at Excell motosports to have them rebuilt and re-valved stiffer. I also put the torsion springs in the stiffest setting and turn the shock springs all the way up. This year I am still bottoming it out, not as much as last year but still enough where I need to do something about it. I am thing the guy I bought the expert from might have put different spring in it since he was just over 100 pounds on a RX-1.
I am 240 with gear on and on a viper.

Does anybody know if Ad-Bovin offered different spring rates for the suspension? Has anybody put different springs on the shocks?

Thanks,
Luke

I just checked the parts schematic I received from AD Boivin and they only list one spring option:

C-375-2650-10650 - DUAL RATE SPRING 185/460

It is possible that the stock spring has worn out and needs to be replaced?

The torsion springs only have one setting?? It should be in the hole with the pressed in bushing..

Last year I was bottoming my skid with the springs cranked up. This summer I had my shocks rebuilt and told the guy I wanted them STIFF since I jump a lot. I'm about 210 all geared up and even with the springs backed all the way off they're still very stiff. I did tell him to re-valve them as stiff as he could though.

VanAmburg use to have dual rate titanium springs for the Expert-X. Spendy but I bet they're nice.
