Thanx all for the info/help.

Ian,

Thanx for pointing out that MG Cycle has those frame to header pipe
clamps, just saw them on the website and they are the exact ones I was
going to bid on on e-bay. Glad I didn't bid because they sold for $21,
and the chrome looked bad, will gladly pay $3 more for brand new ones.
Will take Mark's advice also and tighten up the exhaust nuts when hot,
and also install these clamps, think that will give me some piece of
mind that they won't work loose.

Thanx Again All, what a great board this is!

Hi Keith,

I went with the locking ones on my 70 Ambo but have the standard ones on
my
69 Ambo. So far both have held fast. What I do is smear the threads with

high temp Permatex sealant. Seems to work well. What I really need is a
decent wrench that will fit the ring notches. I plan on making one but
would
prefer to buy one if the price was reasonable.

One problem I have had is that the header gets loose. The nut is tight
but I
guess not tight enough so the header can move a bit. There is a long
distance from the header to the muffler so I went with getting a set of
the
header to frame brackets. I bought mine from MG Cycle for $12 each and I
am
sure the other shops like MG Classics has them as well.

Hope this helps...Ian

 
Greetings Fellow Loopers,

Wanted to get y'alls thoughts on exhaust header locknuts. I have read
and heard about the problems the Loopframes had with the header pipes
vibrating the exhaust nuts loose, resulting in stripped cylinder head
threads. I have seen the locking nut assy at I think Harpers, $37
each!! OUCH!! I was going to bid on some sort of header pipe to frame
bracket that was just on e-bay, but I missed the boat, forgot about the
auction until 15 minutes after it ended. What are y'all doing with your
bikes? Does pretty much everyone have some sort of protection against
the header nut coming loose, and if so, what is the recommended device
to cure it (locking nut, header-to-frame bracket)? I have also heard of
people drilling a hole in a cylinder fin and screwing a chain to it and
the header nut. Should I worry about this or not?

Thanx,
