Upper and Lower Yoke Bolt Torque?
Hello all.
I've just had a bloody awful thought that I've over tightened my yoke bolts.
I've been using a GSF400 Bandit manual as a guide for all my torque settings, but I've just realised that the forks are fitted the usual way round on that bike rather than the USD forks on my GK76A.
Does anyone know what the exact torque range settings should be for the 4 bolts on the lower yoke and the two on the upper?
Cheers,
Hubbskiboy.

I take it they are 8mm screws? if they are the torque range is usually between 20 and 25nm.

Thanks Moforockband.
The good news is that the Crisis is over.
I found the recommended torque settings in the official Japanese GK76A manual I had lying around.
I just couldn't find the right section before and it's all mumbo jumbo anyway apart from the torque ratings.
I'll post them now for everyone to use as I couldn't find them anywhere on this forum -
Surpringly the bolts on the upper and lower yokes have the same torque rating -
180 - 280kg-cm.
Which in ft-lb's equates to - 13 - 20 ft lb's.
And if you want Newton Metres - 17.65 - 27.5Nm.
Luckily I only tightened up my lower bolts and they were still within this spec. Just!!!!

Anthing on the threads? Any kind of thread lubricant will throw off the torque readings...

Just the usual - A bit of bearing grease or impact grease, depending on what I have lying around.
A greased thread isn't going to make much difference.

That depends on what "much difference" means... Is 25% too much?
Ordinarily, torque readings are given for "dry" threads.
