Grip diameters

Here's a quick comparison of grip sizes for the 1300, starting from
the smallest to largest...

Stock grip: 4 1/2"
Flame grip: 5 3/8"
Iso grip: 5 1/2"

Cable Lube

Just do it!

This is one of the most frequently overlooked aspects of preventative
maintenance, yet is key to prolonging cable life and ease of use.

Simple shot of graphite lubricant into the cable opening (pull clutch
lever in to expose cable) and viola! Done!

Stay away from evaporative lubes like WD-40, because they will dry and
leave you with little to no lubrication after a short period of time.
White lithium is another option to reduce wire friction, but because
of its weight, it is difficult to travel through the entire length of
cable. Moly lube (graphite) seems to be the best option. However, if
you have Teflon cables (usually only found on aftermarket cables), do
NOT apply any lubricant other than what is recommended by the cable
manufacturer.

Your cables will reward you with miles upon miles of worry-free use,
and you will find the cables move more freely and are easier to pull.
This is great, especially for us riders with small hands. We need all
the assistance we can get for heavy clutches anyway! ;)
