If I had a dollar for every time I was
asked about torque specifications on
XS650's I'd be a wealthy man. So here
are a couple of tables of specs copied
from the workshop manual. As you can see
all of the specs given are in Metres per
Kilogram force (m/kgs), foot pounds
(ft/lbs) or Inch pounds (in/lbs) Of
course here in Australia we talk in
Newton/metres (N/m) so to do the
conversion from those old ft/lbs to N/m just
multiply by 1.35582 and for in/lbs to N/m multiply
by 0.112984775

Eg. if you have a 10mm
bolt (dimension B) from Table 1. the
correct tension would be :-

25 - 29 ft/lbs

25 ft/lbs X 1.35582 = 33.8955 N/m

29 ft/lbs X 1.35582 = 39.31878 N/m

So the correct tension would be 34 - 39
N/m (rounded)

Tables
on this page were scanned from a Yamaha
XS650B workshop manual and reworked for
ft/lbs and N/m which are more commonly
used than m/kgs here in Australia.

*Standard torque
setting guide by nut & bolt size*

Table 1. is used
where the nuts and bolts are used
together or are screwed onto or into
steel.

Table 1.

**Special
torque settings for various XS650 nuts
& bolts**

Table 2. is used
where these nuts and bolts are used in
alloy or require a special torque
setting.

(Usually less than the standard guide)

Table 2.

**Convert.exe **is
a small program that does conversions
download it and place it on your
desktop, I found it very useful.
