(Your experience may differ)
i bought a set of these from Mikes xs
for my 81 xs 650 and installed em.
no mufflers, no baffles, no re-jetting of carbs
nothing!
Boy did they sound loud!
Since i didn't re-jet the carbs
I had a smell of unspent gas
and I noticed the top end of my motor was getting Hot,
by the air hitting my legs when I rode.
after riding and letting the bike cool down
I checked the plugs
and they were black and "sooty"
I also noticed top end for me was 45-48 mph
did I mention they were loud..LOL
Lastly,
I was scared i was going to cause internal engine damage to the valves running this way
IE "wide open straight pipes"
SO
I broke down, and purchased and installed slip ons,
which increased the pipe's overall length
which in turn, cooled down the bike considerably!
Then I re-jetted the carbs
and now, everything seem to be Back to normal!
(**Top curve heading into engine has turned BLUE though)
again,
Your experience may vary!
Best of luck!
Mine turned gold as well, doesn't bother me. If your looking for a set that wont blue find a set of OEM double wall pipes, almost all aftermarket single wall pipes will discolor.
Man, thanks for the heads up. Just got some 1.75" pipes to go with the EPO's I have. Should look great in stainless
stainless needs polishing to keep its shine, otherwise it will go a brownish burnish

Let's do this!
I really dig the stainless pipes when they discolor.
I installed one of Yamahaxs650`s 2 into 1 headers and reverse megaphone mufflers. With a little bending, tweaking, prying and minor swearing it finally fit. Kickstart lever and brake lever sorta even clear.
I was impressed with the quality of the head pipes and flanges.

How many hours did you spend on that side cover? Look like mirrors.I installed one of Yamahaxs650`s 2 into 1 headers and reverse megaphone mufflers. With a little bending, tweaking, prying and minor swearing it finally fit. Kickstart lever and brake lever sorta even clear.

The rear shocks are RFY part # QR-2B-305. 320mm eye to eye. The upper bushing has to be changed and I don`t think they offer chrome springs anymore.
thank you for the shock information
Wonder how much shipping would be to the states? That's awful kind of you.
The 2 onto 1 exhaust I just used was under $150. With the other small part I ordered it qualified for free shipping. I just ordered the 1 3/4" stainless head pipes. Hell of a deal if their as good as the 2 onto 1 I bought last week.
Stainless head pipes came today. These deserve more than a two thumbs up. Outstanding quality and fitment for sure. I did install a removable baffle. That`s as close to having a muffler as I`ll ever get.

Halfmile, where did you snag the stainless headpipes from? They look amazing. Are they the Stainless Steel ” 1.75″ OD Headpipes from yamahaxs650.com?
