Title: SBK Forks - Triple Tree Clamping torques
Post by: baz on May 07, 2015, 09:25:32 AM
I am in the middle of installing my 748 forks I got from Eric@clubhouseautosport and the upper triple I got bored out from Monsterlover (thanks guys!) and have 2 questions:

1) Should I be expecting the clamping torques on the upper and lower triple bolts to change due to the shim or fork body?  I see stock monster triple clamp (upper and lower) torque target at 20Nm 1-2-1, but 748/996 looks to be 20Nm upper / 14Nm lower.  Is fork clamping bolt torque a function of the forks or the triple tree clamps itself?  Should I be targeting a little less clamping torque on the lower now that I have SBK forks installed?

2) With the upper, bored, stock triple tree, should I be expecting the clamp spacing (gap where you can see the fork through the clamp) to change a little from stock?  My gap when torqued to 15 ftlbs/20Nm on the upper is much smaller than I remember.  Any problems with this?  I only worry about overclamping the upper triple since it has less material, I don't want to crack the clamp. (yes I did regrease the bolts before clamping, and the triple was machined with the bolts screwed in to clamp)

Ok, I guess I'll go with that.

I'm still worried the upper triple clamp is too tight, but I guess I'll just run stock specs of 20nm and keep an eye on cracking.

Yep, definitely screwed up.

I'll do you a favor and take them off your hands.  [evil]
