Well, I took it out but the vid was rubbish...different camera, poor res..
I won't get a chance for a few days now.


I did have lots of exhaust popping on overrun, which was something I had last time too, but it seems more now. The only difference is the 2.68 needle jets and new needles, verses the old 2.66 and well used & worn needles. Second spot for the needles.

The system is as tight as I can get it.

Thanx, I'd just like to hear it idle and rev while warm.


RE, the burbles
My experience with EFI is that burbling and what not are from being rich on over run.

Carbs not so simple maybe. There may be some back feeding of air from the tailpipe end when the throttle is closed due to reversion from the opening.

When you slam the butterfly shut, you cut the air, so the natural initial reaction would be rich.

On an EFI system, you make a setting in the computer to turn the injectors off when the throttle body closes.

My Porsche 930 burbles and coughs flames about 3 feet long on over run. Then I just click and say shut off injectors on over run and it's dead quiet, /Flame off

Are your plugs a little dark or black? How do they look?

I haven't looked at the plugs recently, but they were carbon coated on the outer collar. The firing electrode area seemed ok, not white, more a light grey.

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.

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...

I put my new keihan "Jim Cray specials" up for sale. The bike feels and sounds like a hot rod when on but too loud for me. See this link in flea market:
