Anyone try FCP Engine Mounts on RMZ250?

Wouldn't bother, most seem to break before too long anyway, which is pretty disappointing giving the price....

I haven't tried them. I wonder how much of a difference the kawi torque specs make. Tried that?

Works chassis labs ones are great

I also have the works chassis labs on my 20' RMZ 250, no issues but didn't think the difference was that notable. I'm quite happy with my chassis/suspension after a fair amount of changes. I'm down three rates on the fork springs, two on the shock. After FC had two cracks at re-valving my forks I finally did them myself with the help of the Thumpertalk suspension forum. The valving is probably more like a cross country race setup now. FC also did my RM forks and they were fine as delivered so they did understand me and where I ride. On the back I'm running a Ride link to help stiffen the initial part of the stroke because I run the high speed compression full out with the low speed a little soft to take even more high speed out. In my opinion the forks being so far off as delivered makes the chassis and back suspension feel worse than they really are. I weigh around 175, was a moto vet expert when last I raced in my early 40's but now late 60s lapping a couple times a week on a seventies style natural terrain track (ie no big jumps).
