FWIW- I put ~ 75 miles on my bone stock 82 R100 after I installed the JC's.
I am at 5000" and it runs perfect. Some pop on overrun but nothing I don't like.
The more miles I put on it the quieter it gets...
Definate SOTP power improvement. I feel like a 62 year old hoodlem when I ride it...

With the JC pipes back on, initially I had the new 2.68 NJ's and new needles at the second notch. I had removed the old 2.66's and needles.
The overrun noise was too much however, so I replaced the 2.68's with new 2.66's and slightly tweaked the mixture screw a little leaner. That helped quite a bit.
So now the setup with the JC's is K&N air filter, 2.66 NJ's and new needles @ the 2nd notch.
Now I just need to get the cables synched just a tad better and I'll be happy.
