Looks another project for next winter!

Looking good there Monte,

The Wrap really looks the part , any change in the exhaust sound that you could notice ?

Thanks, rubi76. I had the original LS mufflers on the scooter when "Dino Butt" did his thing. This entire exhaust system project began when Soldier Son -presently 7 kilometers ESE of Kabul International- said the R65 was too quiet. He wanted it to sound like the '81 R65 with its EPCO stainless rorty muffs. I'll have to wait until this time next year to see what he thinks.

The new Norton Peashooters are on a UPS delivery truck somewhere in town and not expected until late this afternoon. They will have a healthier sound than the stockers. Hope to get them installed tomorrow.

Beginning Saturday and for the next eight days, the only motorcycle activity for me will be the occasional ride given to the grandkids. The Austin munchkins will take over our house and energies.

Mufflers arrived on Wednesday about 1530 hours local. I had the boxes opened and the new, beautifully chromed and blingy Norton Peashooter repops temporarily plugged onto the header pipes within fifteen minutes. Sweet looking.

Thursday morning, I was all over this deal by 0930 and completed by 1245 hours.



Some notes regarding the mufflers:

1) As advertised, the muffler stubs are 38mm / 1.375". The fit onto the R65 header pipes is perfect. No beer can or brass strip shims needed.

2) Two tapped mounting lugs are positioned for the Norton motorcycle. As good fortune would have it, one lug lined up perfectly with the R65's  aft muffler attach bracket.

3) It's a clear shot straight through these mufflers! There is an interior pipe about the diameter of the attach stub having three rows of many small louvers punched to catch some of the sound and circulate it through interior chambers. In your dreams, lads. These rascals will be rorty.

All that was required for attachment was to position both muffler's exhaust tips at the same height off the ground, scribe the location on the R65's bracket, centerpunch and drill one hole. Done.



Plenty of meat for the muffler attach with just one bolt. The OEM muffler mount hardware is untouched and will be available if ever needed.

I found it simplified installing the mufflers by first  slightly loosening the aft header pipe clamps and the exhaust nuts. After fitting the new mufflers, everything was snugged up a little at a time and then final torque.

During today's work, the weather went from Spring-like temps of low 70s to a sudden shift to north winds gusting to 40mph, rain and a 20+ degree drop in temps. So, I have not yet had an opportunity to ride with the new modified exhaust system nor score any full bike photos. Soon though.

All seems to be working out with the new wrap and exhaust [smiley=bmw_smiley.gif] I hope the weather down there warms up quickly because we need the ride/audio report with the pictures. Cheers to you and the family. D2

Whoa up. Did I miss the memo? Since when does a hobby have to make sense?  

Amen to that!  Can I get a witness?  I see a lot of mods done to classic bikes, most of which I would never consider doing.  But hey, it's a hobby/passion for most of us, and who are we do say it's wrong.  Keep doing what you're doing Monte.  Besides, it's a labor of love for your son who at this very moment is in harms way for all of us.

May not be the right forum but Dad, you are the best father I could ever wish for.  All this started from a quick sidebar conversation about mods.  Can't say thank you enough for all you do for our family.  Love ya old man.

Can't say thank you enough for all you do

We can't thank {{YOU}} enough for what you do for us and our Country. You're the reason we get to putter around with these bikes without the bad guys on our shores!!

Thanks again

As they might say in Follywood, "That's an exhaust wrap!" And so it is for my latest R65 adventure.

Rains went away and right now it's 80+ degrees, clear and calm. Grand kids can fend for themselves. Time to ride.

After the x-overectomy of the exhaust header crossover tubes, pitiful me can't tell any difference in the '83s operational performance. Nada. The bike starts right up, idles as it should, excellent mid-range ops, pulls like a miniature freight train and still hits the ton without strain. Did it just now...

The header wrap material maybe reduces a little noise at the front end but the rorty Norton peashooters make up for it. Unoffensive exhaust note when puttering through the neighborhoods at 4K revs and below. But twist the loud handle and run it up toward 7K and the music plays. Certainly sounds healthy.

This is what the '83 looked like when I brought it home. Hair-lipped front fender, dented tank, cracked side panels, torn seat cover, dented aft tail piece and thick, orange peel paint. A homely step-child but a good runner.



Today, her body enhancements and skin treatments have her all buffed up and purty, in a good way. I think the Sergeant will approve.

Ya done good, Monte! She is coming right along!

Now all you need is a second disc up front...

[Rob Valdez 79 R65]

That is great, Monte.  You are a wonderful person.  Your son is one lucky guy.

Are those Fiamms under there?   8-)

... Now all you need is a second disc up front...

The two disc vs single disc topic has been well thrashed on this forum.

... Are those Fiamms under there?

And they are freakin' loud, brudda! Both R65s get the cage drivers attention in a BIG way. I did add a new relay circuit to both scooters to handle the additional load.

I sourced the honkers from the same outfit in Arizona where I buy my Cabriolet bits. If anyone drives a German car, this is a good parts resource; often 30% of retail. Been shopping with 'em for over twelve years. http://www.autohausaz.com/
