XL-5 & XL5-2 Frequently Asked Questions
M6 XL-5 & XL5-2
M6 appears to 'hang out' over the edge of the primary case.
Is that normal?
some cases, the M6 actually extends out past the primary case.
This is normal.
there a specifc primary fluid that needs to be used with the
M6 and it's components?
The M6 does not require any special pirmary fluid. The "shoe"
material is designed to be used with any "normal"
primary fluid. Not only do we follow Harley with their suggested
primary fluid, but we also recommend popular after market brands
and have had no instances of brittlness or premature wear when
other primary fluids are used.
"The primary fluid you are currently running will
work fine with the M6".
the SPRINGS ever wear out of get weak? What if I break a spring?
SPRINGS are custom made for us. You cannot buy them in a hardware
store. It is unusual that we ever have to replace springs but
they can always be purchased directly from us.
long will the M6 last?
of our first installations (over 13 years ago) now is approaching
600,000 miles on the M6. He has installed 3 primary chains during
that time, but figures when you can get over 100,000 miles on
a chain you are doing real darn good. AND, he's still on his
long can I expect the SHOE to last?
is not unusual to see well over 100K miles on an M6 shoe. As
long as the correct lubricate is used in the primary case and
the M6 is checked for wear every 20,000 miles, you should expect
to have a long shoe life. Replacement SHOES can always be purchased
directly from us. You do NOT need to purchase a 'complete' M6.
if I loose my extra SHIMS?
can always purchase any of the pieces of the M6 directly from
bike is making a WHIRLING sound. What is it?
M6 does not have any 'hooks' into your system. We are merely
providing a surface for the chain to glide over. In some cases,
we have had a 'whirling' sound reported to us. This sound is
simply the chain gliding over this shoe. It will generally subside
within the first 200-300 miles. Most installations don't hear
this at all. If you should, don't be alarmed. It is not causing
any pre-mature wear on your chain or our shoe.
often should I check the M6?
the unit for wear every 20,000 miles...always keep clean oil.
